2070 Atlantic Hurricane Season

The 2070 Atlantic hurricane season is the most active hurricane season on record, surpassing that of 2005. This season featured 45 depressions, 31 storms, 17 hurricanes, and 8 major hurricanes, which was more activity than the Western Pacific. It also held 5 Category 5's, surpassing the record held by 2005. Ryan had a minimal central pressure of 857 mbars and a wind speed of 220 mph, surpassing the record of 870 mbars held by 1979's Typhoon Tip and surpassing the record of 215 mph held by 2015's Hurricane Patricia. Lillian lasted from August 5-September 17, the longest living storm in the world, surpassing the record of Hurricane John of 1994. It was also the 1st season since 2007 to have a pre-season and a post-season storm

Seasonal Summary
The NHC predicted 18-22 named storms, 7-12 hurricanes, and 3-6 major hurricanes. These variables turned out to be too low. The season ofically began on June 1st and offically ended on November 30th, which limit the date of tropical cyclone development. However, as show with Alex, Brooke, Colin, Danielle, Iota, Thirtysix, and Kappa, tropical or subtropical development is possible outside the season's boundries.

Subtropical Storm Alex
Alex formed as a subtropical depression from an area of low pressure on February 12 at 1200 UTC. 18 hours later, it strengthened to a subtropical storm, recieving the name Alex. Alex continued north until it started to merge with a cold front and move northeast. At this time, it reached its peak of 1002 mbars and a wind speed of 45 mph. On February 14, Alex made landfall near Apalachicola, Florida at its peak. It then started to weaken over land. On February 15, Alex transitioned into a remnant low and was absorbed by the cold front later that day. Damage from Alex was minimal and caused no deaths. Alex is notable for being the earliest Atlantic cyclone to make landfall in the entire basin. It's also notable for being only the 2nd February cyclone in the Atlantic, the first being the 1952 Groundhog Day cyclone

Tropical Storm Brooke
Early on March 16, an extratropical storm fromed off the coast of Honduras and started to move really fast. Later that day, conditions improved and, at 1800 UTC, the system transitioned into a tropical storm and was named Brooke. Brooke continued to move northeast at around 50 mph and started to intensify. On March 17 at 0000 UTC, Brooke reached a peak strength of 50 mph and a pressure of 994 mbars whilst narrowly missing the Outer Banks. At the same time, it started to transition back into an extratropical cyclone. By 1200 UTC, Brooke had slowed to less than 10 mph and had transitioned back into an extratropical storm. It then reached hurricane-force winds and moved over Nova Scotia. It was then absorbed into a larger extratropical storm on March 19. Brooke caused $100 thousand throughout New York. It was also responsible for 2 feet of snow in New Hampshire. 32 people died in the storm. It's also only the 2nd known cyclone to exist in March, with the 1st being a hurricane in 1908

Tropical Storm Colin
An area of low pressure formed into a tropical deprssion at 0000 UTC on May 2. In the course of 24 hours, it strengthened into a tropical storm and was given the name Colin. Colin continued moving mostly northwest and strengthening along the way. At 1800 UTC, Colin reached its peak of 70 mph winds and a pressure of 994 mbars. At the same time, it made landfall south of Welmington, North Carolina. At 0300 UTC, it became extratropical and was absorbed by an approaching cold front. Colin caused $20 thousand in damages and killed 13 people

Hurricane Danielle
On May 30, a subtropical depression formed from a dissipating cold front. At 1800 UTC, it strengthened to a subtropical storm and recieving the name Danielle. At 0300 UTC the next day, it transitioned into a tropical storm and started strengthening. Around the same time, an area of high pressure forced Danielle to move west. At 0500 UTC on June 1st, the storm strengthened into a hurricane with winds of 75 mph and a pressure of 992 mbars. 6 hours later, Danielle made landfall along the Delmarva Peninsula. While making landfall, the area of high pressure started moving east, alowing Danielle to move east with it. It weakened to a 45 mph storm, and transitioned to an extratropical storm at 2100 UTC on June 2nd. It was absorbed into a larger extratropical storm the next day. When Danielle was named, it became the 4th named storm before June 1st, which was a new record in the Atlantic. Danielle caused $150 thousand in damages. No one was killed, but 50 people ended up in the hospital due to flooding

Hurricane Earl
On June 21, a tropical wave formed French Guyana while moving west. On June 22, it briefly enter the Eastern Pacific then reentered the Atlantic, where it stalled off the coast of Panama. At 1200 UTC on June 23, the wave started to move north-northeast and was then classified as Tropical Depression 5. It continued its northeast movement for 6 more hours and turned north. At 0000 UTC on June 24, the depression strengthened into a tropical storm and was named Earl. It continued north and entered a favorable environment where it strengthened into a hurricane. 2 hours later, It made landfall in Cuba with winds of 85 mph and a pressure of 990 mbars. Shear decreased and sea surface tempertatures were above-normal, meaning Earl could strengthen again. It strengthened into a Categroy 2 and later a Category 3, the first major storm of the season. At 1200 UTC, Earl made landfall in Georgia at peak strength with winds of 125 mph and a pressure of 949 mbars. It weakened quickly over land and eventually dissipated on June 26 over Florida. Earl caused $1 million in damages and killed an estimated 102 people. Atlanta saw 20 inches of rain due to the storm

Hurricane Frida
A tropical wave left the coast of Africa late on July 3. By 0600 UTC the next day, the wave organized into a depression, recieving the number 6. 06L continued moving west without intensifying due to wind shear. On July 6, wind shear decreased and by 0600 UTC, the depression strengthened into a tropical storm, recieving the name Frida. Frida gradually intensified is it continued moving westward. Late on July 8, sea surface temperatures started increasing, and on 0300 UTC July 9, Frida strengthened into a hurricane. The instensification continued, and by July 10, Frida became the second major hurricane of the season. Early on July 11, Frida strengthened into a Category 4 hurricane and made landfall in Martinique with winds of 135 mph and a pressure of 942 mbars at 0900 UTC that same day. Intensification continued, and by 0000 UTC on July 13, Frida reach Category 5 intensity. It was at this time that Frida started to slow down in forward motion. On July 15, Frida reached peak intensity with winds of 165 mph and a pressure of 931 mbars. By 0300 UTC on July 16, wind shear started taking its toll on Frida, weakening it back to a Category 4. At 1930 UTC the next day, Frida made landfall in Cuba with winds of 130 mph and a pressure of 947 mbars. Frida also started to weaken and was heading northeast, towards Bermuda. Bermuda prepared for the hurricane, and at 0600 UTC on July 19, Frida made a direct hit on Bermuda with winds of 115 mph and a pressure of 962 mbars. The system weakened to Category 2 intensity, and at 2100 UTC on July 19, Frida transitioned to an extratropical storm with Category 2 hurricane-force winds. The system moved over Newfoundland, and later Greenland, where it was absorbed into a larger extratropical cyclone on July 21. The system caused devastation in both Cuba and Martinique. Damages from both nations amounted to a total of $2 billion and a total 233 fatalities. The system is also notable for its long period of time as a Category 5, staying as one for 3 days.

Hurricane Giovanni
A tropical depression formed on July 9. At 0000 UTC the next day, it strengthened into a tropical storm, reciving the name Giovanni. The storm started moving west-southwest, making landfall(s) in the Cape Verde islands. On July 12, Giovanni became a Category 1 hurricane, and then became a Category 2 on July 13 at 0000 UTC. At 0600 UTC on July 14, Giovanni became a major hurricane, and further strengthened to a Category 4 at 2200 UTC later that day. Narrowly avoiding a landfall in Grenada and Trinidad and Tobago, Giovanni reached its peak wind speed of 155 mph. Due to land interaction with South America, Giovanni weakened to a Category 3 and fell below major hurricane intensity at 1200 UTC on July 17. At 1800 UTC the next day, Giovanni reached major hurricane status once again and reached Category 4 status 18 hours later. On July 20 at 0600 UTC, Giovanni reached its minimal central pressure of 938 mbars. At 2300 UTC later that day, Giovanni fell to Category 3 status again and later made landfall near Biloxi, Mississippi with winds of 115 mph and a pressure of 967 mbars. Giovanni weakened quickly over land and dissipated at 2100 UTC on July 22. Giovanni is responsible for $1 billion in damages and 20 deaths

Hurricane Heather
A tropical depression formed off the coast of Columbia on July 9. The depression turned north and later strengthened into Tropical Storm Heather at 1200 UTC on July 10. Heather then turned back to the west, strengthening into a hurricane along the way. Heather peaked with winds of 80 mph and a pressure of 986 mbars. At around 2130 UTC, Heather made landfall at peak intensity near the Mexico-Belize border. It then dissipated over the mountains of Mexico on July 12. No deaths or damage were reported from this storm

Tropical Depression Nine
At 1200 UTC on July 13, a depression formed off the coast of Nicaragua. It didn't strengthen at all and at 2100 on July 14, it was absorbed into the larger Hurricane Frida. No deaths or damage were reported from this storm

Tropical Storm Ian
An area of low pressure formed a tropical depression at 0000 UTC on July 25. 12 hours later, it became a tropical storm and was given the name Ian, and then made landfall on Bermuda. The next day, Ian made landfall on Nova Scotia and turned post-tropical. Ian was absorbed into a larger extratropical cyclone. Ian's peak was maintained throughout its entire existance as a tropical storm. Ian cause minimal damage and killed 2 people

Hurricane Jeynalynn
A tropical wave left the coast of Africa on July 25. At 1200 UTC on July 30, it became a tropical depression, and then a tropical storm 24 hous later, recieving the name Jeynalynn. At 1200 UTC on August 1, Jeynalynn started to rapidly intensify, reaching hurricane status and then major hurricane status 12 house later. At 1200 UTC on August 2, Jeynalynn reach Category 5 status with winds of 165 mph and a perssure of 934 mbars. 30 minutes later, Jeynalynn made landfall in Jamacia at said intensity and weakened to winds of 160 mph, but restrengthened and reached its peak of 175 mph winds and a pressure of 908 mbars at 0600 UTC on August 3. It then went through an eyewall replacement cycle, weakening it back to 160 mph winds before making landfall in Cuba at around 1900 UTC on August 3. Jeynalynn had then weakened to winds of 150 mph after exiting Cuba, but then went into an area of warm sea surface temperatures and low wind shear where it managed to regain Category 5 strength again. At 1800 UTC on August 4, Jeynalynn made landfall in Tampa, Florida with winds of 160 mph and a pressure of 935 mbars. Soon after, wind shear and land interaction caused it to weaken more than expected, having winds of 120 mph by the time it left Florida. It then strengthened again to winds of 130 mph and a pressure of 943 mbars and made landfall near Wilmington, North Carolina at around 1930 UTC on August 5. It reemerged into the Atlantic again and started to move faster. At 0600 UTC on August 6, Jeynalynn made a landfall on Long Island and a landfall in New Haven, Connecticut, both with winds of 115 mph and a pressure 957 mbars. Immediatly after the landfalls, Jeynalynn finally transitioned into an extratropical strom with Category 2 hurricane-force winds. On August 7, it was absorbed into a larger extratropical storm. In Tampa, the storm surge of Jeynalynn caused almost every minor infestructure to be underwater. In New York City, the top 10 stories fell off of the Empire State Building. Damages amounted $150 billion and killed 1,057 due to the heavy damage to infestructure

Tropical Depression Twelve
A depression formed from a western-moving wave on August 2 at 1800 UTC and started moving north. It never threatened or affected any land and at 1800 UTC on August 3, the depression was absorbed into Hurricane Jeynalynn

Hurricane Kevin
A tropical depression formed from a western moving wave at 0000 UTC on August 3. The depression moved northeast and then northwest, where at 1800 UTC on August 5, the depression strengthened into a tropical storm, recieving the name Kevin. Kevin was forecasted to reach Category 4 intensity and move west, but all of this was prevented due to the influence of nearby Hurricane Jeynalynn, causing it to start moving north. Wind shear died down and sea surface temperatures picked up, allowing Kevin to become a hurricane on August 7, and then a Category 2 on August 8. At 1800 UTC on August 9, Kevin reached its peak intensity of 110 mph and a pressure of 963 mbars while passing south of Bermuda. It then started to weaken and turn north. On August 10, it weakened to a Category 1 hurricane and transitioned into an extratropical cyclone at 1500 UTC while passing east of Newfoundland on August 11. The extratropical cyclone continued to Greenland, where it was absorbed into a larger extratropical cyclone on August 12. Kevin cause minimal damage and was responsible for 6 deaths

Tropical Depression Fourteen
A tropical depression formed from a northwestern moving wave at 1200 UTC on August 3. It never strengthened and never threatened or affected land. At 0600 UTC on August 5, the depression was absorbed into Hurricane Jeynalynn

Hurricane Lillian
A tropical wave eft the coast of Africa on August 4. The wave continued west into warm waters and low wind shear, which allowed it to become a tropical depression at 0600 UTC on August 5. The depression steadily strengthened, becoming a tropical storm at 0000 UTC on August 6 and recieving the name Lillian. Lillian continued west whilst steadily strengthening, and became a hurricane at 0000 UTC on August 7. Lillian tracked into above-average water temperatures, allowing it to rapidly intensify, becoming a Category 4 at 0600 UTC on August 8. Wind shear started to increase, and by August 9, Lillian was back to Category 1 intensity. On August 11, shear started to clear up, allowing gradual intensification, and by August 13, Lillian was back at Caegory 4 intensity. The next day, sea surface temperatures decreased, causiing Lillian to fall to Category 3 intensity, but they then warmed up and Lillian became a Category 4 again on August 15. At around 1900 UTC on August 16, Lillian made landfall near the Reserva de la Biosfera Sian Ka'an (Biosphere Reserve) in the Mexican state of Quinta Roo with winds of 150 mph and a pressure of 949 mbars. Lillian rapidly weakened over land, and when it was on open waters again, it was a tropical storm. It was at around this time the steering currents in the Gulf of Mexico almost stopped completely, causing Lillian to slow down tremendously in forward speed. On August 20, Lillian reached Category 1 status again, and then Category 2 status the next day, but didn't strengthen further due to land interaction.

At 2100 UTC on August 22, Lillian made landfall just south of the Laguna Madre y Delta del Río Bravo (Laguna Madre and Rio Bravo Delta), and was back in the Gulf of Mexico at tropical storm strength due to slightly stronger steering currents. On August 24, Lillian was back at hurricane status once again, and then reached major hurricane status on August 26. On August 27, Lillian reached Category 4 status again, and made landfall west of New Orleans, Louisiana at around 0230 UTC on August 29 with winds of 140 mph and a pressure of 947 mbars. The force of Lillian's landfall in Louisiana was so powerful that the banks of the Mississippi River overflowed and it flowed backwards for 10 days, but New Orleans was spared. A high pressure system from the northwest forced Lillian to move back into the open waters of the Gulf of Mexico, weakening the system due to land interaction. By 1800 UTC on August 30, Lillian had winds of 40 mph, but it then started to rapidly intensify again, and on September 3 at 0000 UTC, Lillian had aquired winds of 135 mph, equivelant to Category 4 intensity. Steering currents strengthened, causing the forward speed of Lillian to pick up and moving it towards Florida. Shortly after 1200 UTC on September 4, Lillian made landfall in Fort Myers, Florida with winds of 145 mph and a pressure of 946 mbars. Lillian emerged into the Atlantic Ocean at Category 1 intensity, but strengthened again and by 1800 UTC on September 6, Lillian had reached Category 4 status for a sixth time. Steering currents started weakening around this time until they crashed on September 9, causing Lillian to slow down again. Under the influence of an upper-level trough, Lillian was forced southwards. At 0300 on September 10, Lillian reached its peak intensity with winds of 155 mph and a pressure of 929 mbars. It was around this time the trough started moving north again, causing Lillian to go north with it.

Steering currents picked up again, causing Lillian to move eastward again. Lillian weakened to a Category 3 hurricane due to an eyewall replacement cycle, but reached Category 4 status for a seventh and final time. At 1630 UTC on September 12, Lillian made landfall over Bermuda with winds of 130 mph and a pressure of 950 mbars. On September 13, Lillian weakened to Category 2 strength, and turned post-tropical with Category 2 hurricane-foce winds at 1500 UTC that day. Forecasters began to believe a Fujiwhara interaction between Ex-Lillian and nearby Hurricane Ryan would begin. Even though Ryan turned to the northeast towards Lillian, the anticipated Fujiwhara interaction never fully started due to a small high pressure system forcing Lillian to the north and forcing Ryan to the west. Late on Septmber 15, Lillian started to show signs of redevelopment. The NHC gave Lillian a 70% chance of redeveloping into a tropical or subtopical cyclone. At 0000 UTC on September 16, Lillian regenrated into a subtropical depression and then a subtropical storm 6 hours later. At around 1700 UTC that day, Lillian made landfall near Bilbao, Spain with winds of 40 mph and a pressure of 1003 mbars. By 0300 UTC on September 17, Lillian ultimately dissipated over Spain. Lillian caused $75 billion in total damages and killed as many as 5 thousand people. Lillian became the longest-lived tropical/subtropical cyclone in the world, being considered tropical or subtropical for an all-time total of 42 days and 12 hours

Hurricane Mike
A tropical depression formed from a western-moving tropical wave on August 7. At 1200 UTC on August 8, it became a tropical storm, receiving the name Mike. Mike continued west and became a hurricane on August 9 and then a Category 2 on August 10. While passing in between Cuba and Haiti, Mike reached its peak intensity with winds of 105 mph and a pressure of 969 mbars at 0600 UTC on August 11. It then started to weaken due to increased wind shear and land interaction between the 2 nations, causing it to fall below Category 2 strength on August 12, and then below hurricane intensity that same day. On August 13, shear took its toll on Mike, weakening it to a tropical depression. At 0100 UTC on August 14, Mike dissipated under the influence of strong wind shear. Mike caused no deaths and only minimal damage. Mike is notable for going between Cuba and Haiti without making a single landfall

Hurricane Nicole
On August 10, a tropical depression formed from an area of low pressure. The depression moved into a pocket of warm water, becoming a tropical storm and receiving the name Nicole. Nicole became a hurricane at 1800 UTC on August 10, and landfall in the Azores at peak intensity with winds of 75 mph and a pressure of 981 mbars. The next day, Nicole became extratropical and was absorbed into a larger extratropical storm. Damage was minimal and 1 casualty was reported throughout the Azores

Tropical Storm Owen
An area of low pressure formed into a tropical depression north of Morocco on August 21. At 0000 UTC on August 22, the depression strengthened into a tropical storm, receiving the name Owen. Owen started to move northeast and ultimately ended up making landfall in Lisbon, Portugal at peak intensity with winds of 40 mph and a pressure of 1003 mbars. On August 23, Owen dissipated over Spain. Owen caused $20 thousand in damages due to rainfall in areas of Spain, Portugal, and Morocco that don't see rain very often. The flooding is responsible for 100 casualties

Hurricane Pacific
A tropical wave with 2 circulations left the coast of Africa on August 29. At 0000 UTC on August 30, the first circulation developed into a tropical depression, while the second circulation started moving northwest and developed into what would become Hurricane Ryan. 12 hours later, the depression strengthened into a tropical storm, receiving the name Pacific. Pacific continued moving westward, battling wind shear and cool sea surface temps. Every time Pacific reached winds as high as 70 mph winds, wind shear or cool ocean temperatures would knock the winds down to as low as 40 mph. Late on September 4, wind shear died down and ocean temperatures increased, causing Pacific to strengthen into a hurricane by 0000 UTC on September 5. Later that day, Pacific reached Category 2 intensity and then became a major hurricane on September 6. At 0000 UTC on September 7, Pacifc reached Category 4 intensity, and then Category 5 intensity 24 hours later. At 0000 UTC on September 9, Pacific reached its first peak with winds of 195 mph and a pressure of 894 mbars. Wind shear started to take its toll on the system, and at 0000 UTC on September 10 Pacific was downgraded to a Category 4 hurricane. It was originally forecasted to continue north and head for the United States, but an approaching ridge forced Pacific to turn southward towards Mexico. On September 11, wind shear caused the system to weaken to a Category 3 hurricane, but it managed to slightly restrengthen due to less wind shear in the area. At 0000 UTC on September 12, Pacific made landfall west of the Laguna de Términos with winds of 125 mph and a pressure of 955 mbars. It emerged into the Pacific Ocean (no pun intended) at 1800 UTC later that day, but due to the mountainous terrain, it had tremendously weakened to the point where it was a minimal tropical storm.

Rapid intensification insued, and soon it was at Category 5 intensity. At 0600 on September 16, Pacific reached its ultimate peak with winds of 215 mph and a pressure of 879 mbars and made landfall near the border between the Mexican states of Guerrero and Oaxaca about 2 hours later. It reemerged into the Gulf of Mexico on September 17 at 0000 UTC, but once again due to the mountainous terrian, it had weakened tremendously to the point where it was a minimal tropical storm again. It started to strengthen again, and by 0000 UTC on September 18, Pacific had reached Category 1 status once again and then made landfall in Tampa 30 hours later with winds of 95 mph and a pressure of 977 mbars. Pacific weakened due to the landfall and when it emerged into the Atlantic Ocean, it had winds of 60 mph. On September 21, Pacific entered an area of warm water and by 0000 UTC on September 22, Pacific reached hurricane status again and started to move south due to a ridge to its north. With the ridge forcing Pacific to the south towards the Bahamas, Pacific managed to reach major hurricane status late on September 22. At 1200 UTC, Pacific reached Category 4 status and could've reached Category 5 status, but land interaction with nearby Cuba prevented this strengthening. On September 24, Pacific started turniing to the north due to the ridge weakening, and then started to transition to an extratropical cyclone. It steadily weakened, and at 1230 UTC on September 27, Pacific made landfall in Newfoundland with winds of 75 mph and a pressure of 979 mbars. Immediatly after the landfall, Pacific fully transitioned into an extratropical cyclone, and was absorbed into a larger extratropical cyclone on September 28. Pacific was responsible for $15 billion in damages and 1,062 casualties. It was also one of the longest-lived cyclones in the world, being considered tropical for 28 days and 12 hours. It's also the only hurricane to cross into the Pacific from the Atlantic and then cross back into the Atlantic from the Pacific.

Hurricane Ryan
A tropical wave with 2 circulations left the coast of Africa on August 29. On August 30, the first circulation developed into what would become Hurricane Pacific, while the second circulation broke off from the newly formed tropical depression and started heading northeast. At 0000 UTC on September 1, the circulation formed into a tropical depression and started heading to the northeast. On September 4, Ryan strengthened into a hurricane and started moving north, intensifying along the way. On September 5, Ryan reached its initial peak with winds of 130 mph and a pressure of 945 mbars and then started to lose intensity due to coller ocean temperatures and higher wind shear. Early on September 7, Ryan weakened back to a tropical storm and weakened to winds of 40 mph early on September 8 and kept this intensity for 24 hours before it started intensifying again. Late on September 9, Ryan was back at hurricane intensity and started to move west and intensify along the way. At 0000 UTC on September 11, Ryan reach major hurricane intensity once again and reached Category 5 intensity at 0600 UTC on September 12, but then started to weaken due to cooler sea surface temperatures. By September 14, Ryan had weakened to Category 3 intensity and started to turn to the northeast again due to the influence of nearby Ex-Hurricane Lillian. Forcaster predicted a Fujiwhara interaction between Ex-Lillian and Hurricane Ryan, but an area of high pressure pushed Lillian to the north and pushed Ryan to the west, preventing a Fujiwhara interaction to fully begin. Because of its influence under Ex-Lillian and increasing wind shear, Ryan had weakened back down to tropical storm intensity by 1200 UTC on September 16. Under the influence of the high-pressure system, Ryan was pushed to the west, becoming extratropical at 1100 UTC on September 17.

Under the influence of heavier wind shear, Ryan turned to the south and degenerated into a remnant low at 0000 UTC on September 19. Forecasters argued that Ryan had dissipated under the heavy shear, but others argued that Ryan was still battling the shear and still had some tropical characteristics. Satellite imagery showed that Ryan was still a remnant low, so they overruled the dissipation theory and kept issuing advisories on Ryan. Late on September 20, wind shear started to greatly die down and Ryan was entering a hugh area of record-warm ocean temperatures, which allowed Ryan to regenerate back into a tropical depression at 0000 UTC on September 21. The NHC was astonished by the rare events taken place with Ryan, quoting that "this system is a system that forms once every 1000 years." Force 13 had ruled that Ryan had completely dissipated, so when Ryan regenerated into a depression they nicknamed it 'Ryan 2'. Early on September 22, Ryan was back at tropical storm intensity and was showing signs of rapid intensification and strengthened into a hurricane at 2330 UTC later that day. On September 23, Ryan underwent explosive intensification, reaching Category 5 status at 1800 UTC later that day and continuing to intensify. Due to fluctuating amounts of winds shear, Ryan would have winds as hish as 185 mph and were then brought down to as low as 160 mph. Early on September 27, Ryan went through a period of rapid intensification, reaching its peak with winds of 220 mph and a pressure of 857 mbars at 0000 UTC on September 28. Due to record-warm ocean temperatures as high as 100°F, Ryan kept this intensity for 72 hours with no changes. After 0000 UTC on October 1, sea-surface temperaturs started to decrease and wind shear started to pick up, causing Ryan to gradually weaken. At 1800 UTC on October 6, Ryan finally weakened to Category 4 intensity and started to quickly move east under the influence of a developing cold front. Ryan weakened to Category 3 intensity at 1800 UTC on October 7 and made landfall on Bermuda with winds of 120 mph and a pressure of 951 mbars 18 hours later.

Ryan fell below major hurricane intensity on October 9 and fell to Category 1 intensity on October 10. At 0600 UTC on October 11, Ryan made landfall at the southwestern most point of Ireland with winds of 80 mph and a pressure of 979 mbars. Immediatly after landfall, Ryan became a post-tropical cyclone with hurricane-force winds. Ryan continued up through Ireland and the U.K. before being absorbed into a larger extratropical cyclone early on October 12. Due to its extreme intensity, large wind field, and slow movement, the nations of the Dominican Republic, Haiti, Cuba, The Bahamas, and the U.S. territory of Puerto Rico were hit the hardest by the storm. In Puerto Rico and The Bahamas, the rain and storm surge were so frequent that some areas of the nation and territory were submerged into the Atlantic or Caribbean by as much as 35 feet for as long as 2-3 weeks. Because of this and the rare landfall in Ireland, damages reach $502 billion and the death toll is 30,642. Ryan became the costliest cyclone in the world as well as the deadliest in the Atlantic, surpassing the Great Hurricane of 1780. Ryan was a Category 5 hurricane for 12 days and 18 hours, surpassing the record of 5 days and 12 hours set by 1961's Typhoon Nancy. Ryan was a tropical cyclone for a total of 36 days and 12 hours, making it the 2nd longest-lived cyclone in the world behind Hurricane Lillian

Tropical Storm Shelby
A tropical depression formed on September 9 from a western-moving wave. At 0000 UTC on September 10, the depression became a tropical storm, recieving the name Shelby. Shelby didn't strengthen further than 40 mph and a pressure of 999 mbars. After 1800 UTC on September 10, Shelby made landfall near the Mexico-Belize border and weakened to a tropical depression inland. On September 11, Shelby was absorbed into the larger Hurricane Pacific. The storm caused minimal damage and no casualties

Hurricane Toby
A tropical storm formed from a westward-moving wave at 0000 UTC on September 10, recieving the name Toby. Toby continued westward, steadily strengthening along the way to become a hurricane on September 11 and then a Category 2 at 1200 UTC that same day. Late on September 11, Toby entered an area of slightly higher wind shear, causing it to weaken back to a Category 1 by 0000 UTC on September 12, but then the wind shear died down, which allowed it to become a Category 2 again later that day. At 0000 UTC on September 13, Toby reached its peak intensity with winds of 100 mph and a pressure of 970 mbars, but then weakened again due to increased wind shear. At around 0000 UTC on September 14, Toby made landfall at the Reserva Natural Punta Gorda (Punta Gorda Natural Reserve) in Nicaragua with winds of 95 mph and a pressure of 975 mbars. By 1800 UTC later that day, Toby had entered the Eastern Pacific basin and was monitered as an Eastern Pacific storm, but still having its name retained. It would go on to be the worst storm in the history of Hawaii and the only storm to make a landfall in Alaska. In Central America, Toby caused $5 million in damages and killed 242 people.

Victoria gradually weakened over land before dissipating over the Chattahoochee National Forest in the United States on September 19. Damages from Victoria amounted to $10 million and 15 casualties were reported

Tropical Storm Winston
A tropical depression formed from a western-moving wave on September 17. At 1200 UTC later that day, the depression strengthened into a tropical storm, recieving the name Winston. Due to the influence of a ridge to its north, Winston moved west-northwest, steadily strengthening along the way. At 0600 UTC on September 19, Winston reached its peak intensity with winds of 70 mph and a pressure of 996 mbars before making landfall south of Georgetown, Guyana at said intensity. Winston rapidly weakened over land before dissipating at 2100 UTC on September 19. Winston caused minimal damage and no fatalities. Winston is notable for being the southernmost landfalling cyclone in the Atlantic

Tropical Storm Alpha
A tropical depression formed from a western-moving wave late on September 21. At 1200 UTC on September 22, the depression was upgraded to a tropical storm, recieving the name Alpha and making the 2070 season the 1st season since 2005 to use the Greek alphabet after the list of names was exhausted. 6 hours later, Alpha reached its peak with winds of 65 mph and a pressure of 998 mbars. Wind shear caused by the outflow of nearby Hurricane Pacific started to weaken the storm tremendously, and by 0600 UTC on September 23 Alpha had weakened to winds of 40 mph and a pressure of 999 mbars. About 4 hours later, Alpha made landfall south of Barahona, Dominican Republic at said intenisty and weakened tremendously indland before being absorbed into Hurricane Pacific early on September 24. Alpha caused minimal damage and no one was killed in the storm

Tropical Storm Beta
A tropical depression formed off the coast of Africa early on September 24. At 1200 UTC the depression became a tropical storm, recieving the name Beta. Beta cointinued north while strengthening along the way and started turning east. At 0600 UTC on September 25, Beta reached its peak intensity with winds of 70 mph and a pressure of 997 mbars. It then started weakeneing due to land interaction and wind shear, followed by a landfall near Nouakchott, Mauritania with winds of 40 mph and a pressure of 1002 mbars shortly after 1800 UTC later that day. On September 26, Beta ultimately dissipated over Mauritania. Beta caused $25 million in damages and killed 542 people due to areas in Mauritania not seeing rain very often. Beta is notable for being the only tropical cyclone to make landfall in Africa from the Atlantic Ocean.

A tropical depression formed on September 29 from a western-moving wave. At 1200 UTC later that day, the system strengthened into a tropical storm, recieving the name Gamma. At 0000 UTC on September 30, Gamma reached its peak intesity with winds of 45 mph and a pressure of 1000 mbars just as it was making landfall in Nicaragua. The storm then dissipated over Central America. Gamma caused minimal damage and no casualties

Hurricane Delta
A tropical storm formed from an area of low pressure on October 2, recieving the name Delta. Delta continued north, gradually strengthening along the way and managed to reach hurricane status at 1800 UTC on October 2. 6 hours later, Delta reached its peak intensity with winds of 80 mph and a pressure of 995 mbars followed by a trend of gradual weakening. At 1200 UTC on October 3, Delta made landfall in Quebec with winds of 70 mph and a pressure of 998 mbars. Immediatly afterwards, Delta became extratropical and was absorbed into a larger extratropical cyclone on October 4. Delta is notable for being the only tropical cyclone to ever make landfall in Quebec. Because of this rare landfall, Delta cause $1 million in damages and killed 322 people

Hurricane Epsilon
A depression formed on October 2 from a stalling tropical wave off the coast of Puerto Rico. The depression moved south, then southwest, and finally started moving east by October 4. As it was starting to turn east, wind shear decreased and ocean temperatures increased, allowing thhe depression to start organising. By 1800 UTC that day, the depression had strengthened into a tropical storm and recievied the name Epsilon. Epsilon continued moving east into warmer waters, allowing the system to rapidly intensify. At 0000 UTC on October 6, Epsilon reach hurricane status, followed by major hurricane status 12 hours later and Category 4 intensity another 6 hours later. On October 7, Epsilon started to stall and move south, causing further strengthening and devastation in Dominica and Martinique. Early on October 8, Epsilon turned towards and started heading towards the west-northwest, but weakened to Category 3 intensity due to an eyewal replacement cycle. At 1800 UTC on October 9, Epsilon reach Category 4 intensity, followed by Category 5 intensity 12 hours later. At 0000 UTC on October 11, Epsilon reached peak intensity with winds of 175 mph and a pressure of 914 mbars, but then started weakening again due to cooler ocean temperatures. Around 15 hours later, Epsilon made landfall in Jamacia with winds of 160 mph and a pressure of 925 mbars. Early on October 12, Epsilon reemerged into the Caribbean with winds of 140 mph, but started to strengthen again while heading towars the Yucatan Peninsula. By 0600 UTC on September 13, Epsilon reached winds of 160 mph, equivelent to Category 5 intensity, but didn't strengthen further due to interaction with the Yucatan Peninsula. Shortly before 0000 UTC on October 14, Epsilon made landfall in the Yucatan Peninsula with winds of 160 mph and a pressure of 929 mbars.

Steering currents collapsed, causing Epsilon to stall over the Yucatan and rapidly weaken. By October 15, Epsilon was in the Yucatan Channel and started to move north-northwest due to steering currents gaining strength. Epsilon started to rapidly intensify again, and by 1800 UTC on October 16, Epsilon reach Category 5 status for a third and final time. Shortly after 0000 UTC on October 17, Epsilon made landfall in Panama City Beach, Florida with winds of 165 mph and a pressure of 930 mbars. Epsilon quickly weakened over land before degenerating into a remnant low later that day. The low continued north before dissipating near Lake Huron on October 19. Still recovering from Hurricane Frida, Martinique saw more devastation from Epsilon while Dominica, the Yucatan, and Panama City Beach saw other types of devastation from the storm. Epsilon cause $127 billion in damages and killed 987 people

Hurricane Zeta
A tropical depression formed from an area of low pressure on October 20 and became a tropical storm at 1800 UTC later that day, recieving the name Zeta. Zeta contined west and made landfall in Fort Myers at 0300 UTC on October 21 with winds of 50 mph and a pressure of 995 mbars. It weakened while inland and emerged into the Atlantic Ocean as a tropical depression, but started to restrengthene and head northeast. At 1800 UTC on October 22, Ztea reached hurricane intensity and then Category 2 intensity 12 hours later. At 1200 UTC on October 23, Zeta made landfall in North Carolina with winds of 100 mph and a pressure of 972 mbars and weakened back to Category 1 intensity. At 1200 UTC on October 24, Zeta reached Category 2 staus again and reached peak intensity with winds of 105 mph and a pressure of 969 mbars just before landfall in New York City 6 hours later. Zeta rapidly weakened inland and transitioned into an extratropical cyclone on October 25 before dissipating later that day. Zeta caused minimal damage in Fort Myers, but people in the Outer Banks and New York City were concerned about damage due to the continued recovery efforts from Hurricane Jeynalynn. Zeta caused less damage than expected, causing only $2 million in damages and killing only 6 people.

Tropical Storm Eta
A tropicl depression formed on November 12. At 0000 UTC the depression became a storm, recieving the name Eta.

Subtropical Depression Thirtysix
A subtropical depression formed at 0000 UTC on December 27. The system was mmoving southwest towards the Cape Verde islands before turning to the north west at 0000 UTC on December 28. By 2100 UTC on December 28, the depression was absorbed into the cold front that would later spawn Tropical Storm Kappa. No casualties and minimal damage were reported in the Cape Verde islands.

Tropical Storm Kappa
A tropical depression formed from a cold front that absorbed Subtropical Depression Thirtysix on December 30. At 0000 UTC on December 31, the depression became a tropical storm, recieving the name Kappa. Kappa then completed an anticyclonic loop and started heading west. At 1800 UTC on January 2, Kappa reached its peak intensity with winds of 60 mph and a pressure of 995 mbars. Wind shear and cold sea surface temperatures started to rapidly weaken the storm, causing it to fall below tropical storm intensity by 0000 UTC on January 3 before dissipating 7 hours later. Kappa is know for being one of 3 storms to span 2 calendar years, with the 1st being Hurricane Alice of 1954 and Tropical Storm Zeta of 2005.
