2020 Atlantic hurricane season (Sandy156)

This article is underconstruction!

Based off of this I made less than a year ago:

The 2020 Atlantic hurricane season was an above-average season with 18 named storms, 12 hurricanes, and 6 major hurricanes forming this year. In the midst of March, a La Niña formed, greatly raising the expected number of storms that’ll form this year. The season officially started on June 1 and ended on November 30, although storms may form at any time of the year.

Tropical Storm Arthur
An area of low pressure formed on June 4, drifting through the Caribbean Sea. It gradually organized due to the warm waters there. The NHC began tracking it on June 7, giving it a medium chance of forming. A couple of days later at 00:00 UTC on July 9, it eventually developed into Tropical Depression One, the first system of the season. It then drifted northwest, heading into the Yucatan Peninsula. On June 11 03:00 UTC, it made landfall while still being a tropical depression. Despite the landfall, it weakened only slightly, not degenerating into a remnant low. On June 12 at 00:00 UTC, it entered the Gulf of Mexico and then started gradually intensifying. On June 14 at 06:00 UTC, it strengthened into a tropical storm, earning the name Arthur. It headed west-northwest to the state of Texas. It eventually reached its peak intensity on the 15th at 18:00, 12 hours before its landfall. It had winds up to 60 mph (95 km/h) and a minimum pressure of 994 mbar. At the time of its landfall, it started to demise gradually, becoming a tropical depression at 00:00 UTC on June 16. It then degenerated into a remnant low later that day, getting as far as Kentucky before it dissipated.

In total, Arthur caused $188 million in damages and 3 deaths indirect and direct.

Hurricane Bertha
A tropical wave emerged off the coast of Africa on June 20, slowly drifting west while gradually organizing over warm waters. On June 24, it was finally recognized by the NHC and on June 26 at 18:00 UTC, it was upgraded to Potential Cyclone Two, the NHC giving it a 90% chance of forming in the next 48 hours. It had tropical storm strength six hours later and at 00:00 UTC on June 28, it was finally a tropical storm, the NHC naming it Bertha. It then intensified a little quickly and on June 30 at 06:00 UTC, it was upgraded to a hurricane and exactly one day later, strengthened into a Category 2 hurricane. It reached its first initial peak intensity on July 1 at 12:00 UTC, with 100 mph (160 km/h) winds and a pressure of 978 mbar. Due to it moving into a small area of wind shear, it abated slightly gradually, falling back to a Category 1 on July 2 06:00 UTC and then a tropical storm the next day, as it made a small loop around. Once it fully completed its loop, it exited the area of wind shear, and started gradually intensifying again. On July 4 at 12:00 UTC, it intensified back into a Category 1 hurricane and 18 hours later, strengthened into a Category 2. On July 7 at 12:00 UTC, it further intensified into a major hurricane, reaching its second initial peak intensity another 18 hours later, with winds up to 120 mph (190 km/h) and a minimum pressure of 960 mbar. During the period of July 8, 18:00 UTC to July 9, 12:00 UTC, Bertha then impacted some islands in the Lesser Antilles, hitting the islands of Barbuda, Saint Barthélemy, Saint Martin/Sint Maarten, and Anguilla respectively. At the same time, it also underwent an eyewall replacement cycle, causing it to start weakening. It fell below major hurricane strength on July 9, 12:00 UTC and weakened to a Category 1 24 hours later. It took a turn to the north and then further diminished into a tropical storm on July 11 at 12:00 UTC, where it held that strength for 12 hours before intensifying back into a hurricane. That same time, it then took a sharp turn to the west. On July 12 at 18:00 UTC, the hurricane unexpectedly rapidly intensified, reaching major hurricane strength on July 14, 06:00 UTC and then a Category 4 12 hours later. It reached its peak intensity on July 15, 06:00 UTC, with maximum winds of 140 mph (220 km/h) and a minimum central pressure of 938 mbar (hPa). After that, it began another eyewall replacement cycle, again diminishing the hurricane as it approached the Carolinas. It weakened to a Category 3 on July 16, 06:00 UTC and then fell below major hurricane on July 17, 12:00 UTC. Bertha made its landfall in southern North Carolina on July 18 at 00:00 UTC. It quickly abated over land, weakening to a tropical storm on July 19, 00:00 UTC and then to a tropical depression 12 hours later. It then became a remnant low on July 20, reaching Canada quickly as it attained tropical storm force winds.

Bertha caused $11.72 billion in damages and 75 deaths (68 direct and 7 indirect) in total.

Hurricane Cristobal
In late June, the NHC began monitoring an area in the open Atlantic for tropical or subtropical development within the next several days. It drifted northwest for several days while very gradually organizing. It was finally designed as a potential cyclone, the NHC giving it a 90-100% chance of forming. It quickly attained tropical storm strength on July 4, 00:00 UTC. It then fully acquired subtropical characteristics, thus it was developed into Subtropical Storm Cristobal at 18:00 UTC that day. For 30 hours, it stayed subtropical, slowly transitioning into a tropical storm. Cristobal then became fully tropical on July 6, 00:00 UTC. At 18:00 UTC, it eventually became a hurricane and on July 7, 06:00 UTC, reached its peak intensity with sustained winds of 85 mph (140 km/h) and a minimum pressure of 986 mbar (hPa). Entering very cold waters, it weakened to a tropical storm on July 8, 06:00 UTC and then transitioning into a extratropical cyclone 12 hours later.

Hurricane Dolly
In early July, a tropical wave emerged off the coast of Africa. For several days, it advanced westward for several days, no change in organization. 2 days after it entered the Caribbean Sea, the NHC tracked it, giving it a 0/0% chance of forming. It drifted slowly in the Caribbean, very gradually organizing. Finally, on July 14 at 12:00 UTC, it developed into Tropical Depression Four. Due to increasing wind shear, the system struggled to strengthen for a few days, trying to maintain being a tropical depression. On July 17, the wind shear started to subside, the system now able to intensify. On July 18, 00:00 UTC, the depression finally became a tropical storm, named Dolly. It turned northwest, gradually intensifying as the wind shear completely impacted the storm no more. It then strengthened more rapidly and on July 19, 12:00 UTC, it became a hurricane. The hurricane now turned north-northeast right toward Cuba after it was upgraded to a hurricane. It became a Category 2 hurricane on July 20, 06:00 UTC, and reached its peak intensity 12 hours later right before landfall. It had maximum winds of 100 mph (155 km/h) and a minimum pressure of 984 mbar (hPa) at the time of its peak. 12 hours later, on July 21, 06:00 UTC, Dolly made landfall in the southern province of Ciego de Ávila. Intensity decreased slightly between its peak intensity and landfall, with 5 mph (10 km/h) decrease in wind speed and 3 mbar (hPa) increase in pressure. However, it remained a Category 2 until it exited Cuba, on July 21 at 15:00 UTC, where it weakened back to a Category 1. For the period of July 21, 18:00 UTC to the next day at 18:00 UTC, it then impacted the Bahamas, falling below hurricane strength on July 22, 12:00 UTC. Once it exited the Bahamas, however, it continued to abate, weakening to a tropical depression on July 23, 18:00 UTC. 12 hours later, it became a tropical storm again, while gradually intensifying abruptly. It strengthened into a hurricane on July 25 at 18:00 UTC and then reached its secondary peak intensity 6 hours later, with winds up to 80 mph (130 km/h) and a minimum pressure of 989 mbar. After that, due to increasing wind shear, it started to diminish. It weakened back to a tropical storm on July 26, 06:00 UTC, and then to a tropical depression again on July 27, 00:00 UTC. It eventually became a remnant low at 18:00 UTC that day, which dissipated the next day.

Dolly caused $458 million of damages and killed 18 people direct and indirect in Cuba alone.

Tropical Storm Edouard
An area of low pressure formed in the Gulf of Mexico on July 16, the NHC monitoring it. The system was in warm waters with no wind shear, causing it to organize. On July 19 at 12:00 UTC, it developed into Tropical Depression Five, the system continuing to intensify. Later, on July 20 06:00 UTC, it strengthened into Tropical Storm Edouard. After that, it turned towards the north, heading straight to the Florida Panhandle. 12 hours later, it reached its peak intensity, with 50 mph (85 km/h) winds and a minimum pressure of 997 mbar. Due to land interaction, it weakened slightly, winds dropped 5 mph (10 km/h) and the pressure upped to 999 mbar at the time of its landfall in the Florida Panhandle on July 21, 12:00 UTC. It started to abate, falling into a tropical depression 6 hours later and then into a remnant low on July 22, 06:00 UTC.

Edouard caused $84 million of damages and 2 fatalities in the Southeastern U.S.

Tropical Depression Six
An area of low pressure formed on July 27, 250 mi (400 km) northwest of Bermuda. It organized gradually, despite entering cooler waters. On July 30, 06:00 UTC, it was classified as a tropical depression. The system saw little to no chance in strength during its lifetime and On July 31, 12:00 UTC, it became a remnant low and 12 hours later, it dissipated.

Hurricane Fay
A tropical wave emerged off the coast of Africa on July 26. It passed over Cape Verde and then moved into the open Atlantic, where it started to gradually organize due to warmer waters and low to no wind shear. It was recognized by the NHC on July 30, giving it a 0% chance of forming in the next 48 hours. It then became a potential tropical cyclone on August 2, steadily but quickly organizing as it attained tropical storm force winds. On August 3, 06:00 UTC, it developed into Tropical Storm Fay, heading northwest. It then took a curve to the west, gradually intensifying over warm waters. On August 5, 12:00 UTC, it suddenly rapidly intensified, going from a tropical storm to a Category 3 major hurricane in a period of 24 hours from August 5, 18:00 UTC, to August 6, 18:00 UTC. It reached its peak intensity at 06:00 UTC the next day, with winds up to 120 mph (195 km/h) and a minimum pressure of 971 mbar (hPa). Then, an eyewall replacement cycle undergoes for this hurricane, diminishing it to a Category 2 on August 8, 00:00 UTC, and then to a Category 1 on August 9, 06:00 UTC. The hurricane now enters cooler waters, further weakening below hurricane strength briefly on August 10, 06:00 UTC, before it became a hurricane again 6 hours later. Waters are getting cooler for the system and on August 11, 00:00 UTC, it weakened back to a tropical storm, starting to transition into a extratropical cyclone. On August 12 at 06:00 UTC, it eventually became fully extratropical, heading northwest to Great Britain. While it’s at its approach, it attained hurricane force winds for 30 hours before weakening back to tropical storm strength. It hit Ireland on the morning of August 14 and then Great Britain that afternoon.

Tropical Storm Gonzalo
An area of low pressure formed in the open Atlantic on August 5. It drifted west, interacting a little with Hurricane Fay, which was about 300 miles away. After it’s done interacting, the NHC began tracking it, giving it a low chance of forming, while the system gradually organized due to warm waters. On August 11 at 18:00 UTC, it developed into Tropical Depression Eight, now gradually intensifying. On August 13, 00:00 UTC, it strengthened into a tropical storm, named Gonzalo by the NHC. It reached its peak intensity that time, with 40 mph (65 km/h) winds and a pressure of 1001 mbar (hPa). Wind shear started to increase, causing it to diminish. It weakened to a tropical depression at 12:00 UTC that day and then on August 14, 12:00 UTC, it was downgraded to a remnant low.

Hurricane Hanna
An tropical low formed on August 6, in the Caribbean Sea. It headed northwest, slammed into the Yucatan Peninsula, and then entered the Gulf of Mexico a few days later. It turned right toward the state of Florida and then started to organize. On August 12, 12:00 UTC, it was designated as Tropical Depression Nine. Then on August 13, 12:00 UTC, it intensified into Tropical Storm Hanna, about 1,000 mi (1,600 km) west of Florida. It reached its initial peak intensity 6 hours later, with winds of 45 mph (70 km/h) and a minimum pressure of 998 mbar. It struck Florida at its initial peak intensity at 21:00 UTC that day, its landfall diminishing the storm into a tropical depression on August 14, 00:00 UTC and then a remnant low at 12:00 that same day.

Hurricane Isaias
On August 26, a tropical low formed in the eastern verge of the Caribbean Sea. It drifted westward over warm waters, very slowly organizing. It was tracked by the NHC on August 28, giving it a low chance of forming. On August 31, it was designated as a potential tropical cyclone, attaining tropical storm force winds at 18:00 UTC that day. On September 1st, 06:00 UTC, it developed into Tropical Storm Isaias, about 1750 mi (2820 km) northeast from De Caratasca Lagoon at the country of Honduras, heading west to the Yucatan Peninsula. A while later, it then suddenly started rapidly intensifying in very favorable conditions, becoming a hurricane on September 2, 06:00 UTC, and then jumped straight into a Category 4 major hurricane 12 hours later. Later on, it reached its peak intensity on September 3 at 00:00 UTC, with maximum winds of 150 mph (240 km/h) and a minimum pressure of 934 mbar (hPa). Due to its approach to land, it weakened slightly. It made landfall in Belize technically 2 times, one in a peninsula near San Pedro at 12:00 UTC that day, and another in mainland Belize 6 hours later, with maximum winds of 145 mph (235 km/h) and a minimum pressure of 939 mbar (hPa). It rapidly weakened during its landfall, falling below major hurricane strength on September 4, 06:00 UTC, and below hurricane strength six hours later. Even though it entered waters in the Gulf of Mexico at 21:00 UTC that day, it still abated, becoming a tropical depression on September 5, 06:00 UTC.

Tropical Depression Eleven
A low pressure area formed on September 2 and it gradually organized in the warm waters. It developed into Tropical Depression Eleven on September 6, 06:00 UTC. Increasing wind shear made the system stall in intensification. Therefore, it reached its peak intensity at 18:00 UTC with 35 mph (55 km/h) maximum winds and 1002 mbar (hPa) minimum pressure. The system started to weaken with its wind shear. It dissipated on September 8 at 06:00 UTC.

Hurricane Kyle
On September 12, a tropical wave emerged off of the coast of Africa. For a few days, it drifted westward, with no change in organization. On September 16, it started to organize, the NHC now tracking the system. Then on September 18 at 06:00 UTC, it was designated as a potential tropical cyclone, attaining tropical storm force winds twelve hours later. Eventually, it developed into a tropical storm, named Kyle by the NHC, on September 19 at 12:00. Moving westward gradually intensifying, Kyle was in warm waters with low wind shear. Finally on September 23 at 00:00 UTC, Kyle strengthened into a hurricane, three and a half days after it developed. Kyle didn’t strengthen further into a Category 2 hurricane until September 25, 18:00, when it attained 100 mph (160 km/h). From there on until September 31, it kept on influencing between a Category 1 and 2, with the exception of weakening to a tropical storm on September 27, 18:00 UTC, while it took a sharp turn southwest. At the third time of strengthening into a Category 2, it was approaching the island of Guadeloupe, which is in the Lesser Antilles. It hit the island on September 29 at 00:00 UTC, with sustained winds of 105 mph (170 km/h) and a minimum central pressure of 970 mbar. After it hit the island, it immediately weakened to a Category 1, six hours later. The hurricane strengthened back to a Category 2 hurricane on September 30, 06:00 UTC. 6 hours later, it unexpectedly started rapidly intensifying, jumping from a Category 2 to a Category 5 hurricane in a margin of 12 hours.

Storm names
The following list of names was used for named storms that formed in the North Atlantic in 2020. The names not retired from this list will be used again in the 2026 season. This was the same list used in the 2014 season. The names Isaias, Paulette, and Rene were used for the first time this year.

Season effects
This is a table of all the storms that have formed in the 2020 Atlantic hurricane season. It includes their duration, names, landfall(s), denoted in parentheses, damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a tropical wave, or a low, and all the damage figures are in USD. Potential tropical cyclones are not included in this table.
