2013 Bikini Bottom hurricane season

The 2013 Bikini Bottom hurricane season is an active hurricane season in tropical cyclone meteorology. Following a destructive and a 357-death 2012 Bikini Bottom hurricane season, newer technology to improve hurricane forecasting debuted. The season began on June 1, 2013, and it will end on November 30, 2013, dates that conventionally delimit the timeframe period for tropical cyclogenesis. However, if a storm forms between January 1, 2013 and December 31, 2013, it will factor into the season total, as was the case with Tropical Storms Adrian and Brad.

Season summary
After 357 people died (349 directly, eight indirectly) in the 2012 Bikini Bottom hurricane season, curious scientists (including Sandy Cheeks), wanted to make more advanced machines to forecast a major hurricane (Category 3 or higher on the Saffir-Simpson Hurricane Scale) by February 2013.

Seasonal forecasts
Mr. Thicklebach, a famous scientist who is the brother of Judge Thicklebach, gathered a group of scientists on December 16, 2012 to predict the 2013 Bikini Bottom hurricane season's total activity. Thicklebach's hypothesis for the season's activity was 9.2 total storms, five hurricanes, and 1.3 major hurricanes. Other scientists are currently developing other hypotheses for the season's activity. Thicklebach's hypothesis concludes that the season will be below average compared to the 2012 season.

On December 21, 2012, Thicklebach met with Rina Bottom's high-tech paranormal scientist and investigator, Jack Kerry. Kerry had other different scientific fields he created for the 2013 season. They described the season to be slightly more active. Kerry and Thicklebach will meet again on March 16, 2013 to retire the destructive hurricane names for 2012 and subsequently conclude the season's activity. On August 15, the current hurricane season forecast is calling for 18 named storms, 9 Tropical Storms, 9 Hurricanes, and 4 Major Hurricanes.

Accumulated Cyclone Energy
The table above shows the ACE for each storm in the season. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is calculated for only full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength. Subtropical cyclones are not included in the ACE.

Storm names
The following list of storms will be used to name storms that form in the Bikini Bottom Weather Center's area of responsibility during 2013. Retired names, if any, will be announced at Session XXVII of the Bikini Bottom Meteorological Organization on April 21, 2014. Because this is the first time this naming list has been used since naming begun last year, it will mark the first time any of these names have been used. Names of active storms are marked in bold, and unused names are marked in.

Please DO NOT change the storm names.

Tropical Storm Adrian
An unexpected low pressure area formed on January 25. This non-tropical low struggled to form until January 31, 2013, when it was upgraded into a tropical depression. Six hours later, the depression was upgraded to a tropical storm and named Adrian. Adrian is the earliest forming Bikini Bottom tropical cyclone in two years of reliable record keeping, as hurricane are usually not expected to form until late May or early June. Adrian dissipated on February 4 after being abosrbed into Winter Storm Mandarine by a Fujiwhara interaction, maintaining hurricane intensity for only four hours. Adrian however was studied further on June 19, scientists were then puzzled when they found out that there were no gusts in Adrian, Due to this, they eventually downgraded the storm into a strong tropical storm.

Tropical Storm Brad
Another unexpected low pressure area formed off the coast of Stanica Bottom in the southern Bikini Atoll region on April 29. Later, the system became Invest 80B and then later Tropical Depression Two; this storm then became a tropical storm on the evening of May 1 and was given the name Brad. The tropical storm reached its maximum intensity of 65 miles per hour on May 2nd, the storm then dissipated the next day, May 3rd off the coast of the northeast section of Bikini Bottom.

Hurricane Cal
On June 9, a broad area of accelerating thunderstorms appeared in the center of the Bikini Atoll area, eventually intensifying into Tropical Depression Three the next day. The depression was later upgraded into a tropical storm and given the name Cal. Five days later, on June 15, Cal degenerated into a remnant low; it killed only one person at Bikini Bottom's Goo Lagoon.

Hurricane Dominic
On June 17, the Bikini Bottom Weather Center began monitoring a vigorous tropical wave coming off of Bikini Atoll; it was later upgraded into Tropical Depression Four the next day. On June 19, one day later, the depression was upgraded into Tropical Storm Dominic. The storm soon encountered hurricane-force wind gusts on the night of June 20 and was subsequently upgraded to a Category 1 hurricane. The projected path of Dominic forecasted it reaching category 2 intensity, which later panned out to be true.

Tropical Storm Eris
On June 21, as Hurricane Dominic intensified out at sea, a tropical wave developed off the coast between Rock Bottom and Rina Bottom. The next day, the wave appeared to have developed significantly on satellite imagery. Next, on June 23, the disturbance was upgraded into Tropical Depression Five. The depression developed significant convection, and was further upgraded to Tropical Storm Eris. Eris did not last long, as it dissipated within 48 hours.

Tropical Storm Felicia
On July 5, the Bikini Bottom Hurricane Center began to notice convection developing in a tropical wave. The next day, the wave developed further up to the point where it was classified as Tropical Depression Six. Within 24 hours, the depression intensified even further and was reclassified Tropical Storm Felicia. The storm raidly crossed Bikini Bottom, maintaining a fast foreward speed. Felicia ultimately became extratropical on July 11.

Hurricane Gilma
The Bikini Bottom Hurricane Center began investigating a blob that formed extreme south on August 15, the disturbance got more well developed and was classified as Tropical Depression Seven on August 16. The next day, it strengthened into Tropical Storm Gilma. The seventh named storm of the 2013 season.

Tropical Storm Harvey
Tropical Storm Harvey formed on August 22.It transformed into a weak Tropical Storm in the afternoon hours of August 22 it stayed the same intensity for a few days before it went over cooler SST's and high wind shear it quickly weakened into a remnant low 2 hours later with only a few sporadic showers remaining associated with it then dissipated completely in the evening  hours of August 25th.

Hurricane Ileana
The Bikini Bottom Hurricane Center began monitoring another tropical wave that developed on August 28; two days later it strengthened into Tropical Depression Nine. Four hours later, it strengthened further into Tropical Storm ''Ileana. ''Ileana later became a significant category 3 hurricane on September 5. Ileana reached its peak intensity of 140 mph on September 6 witch is category 4 strength, Ileana then dissipated on September 10.

Hurricane Jack
The Bikini Bottom Hurricane Center started noticing some convection developing east of Ileana, on Labor Day, September 2. Two days later,after rapid intensification, it strengthened into Tropical Depression Ten. At the 9 AM advisory. A few hours later it strengthened into Tropical Storm Jack. Jack then strengthened into a category 1 hurricane on September 6, it weakened back to a tropical storm on September 9th, and then became post-tropical on September 10th

Hurricane Katie
The Bikini Bottom Hurricane Center started to investigate a tropical wave with a closed circulation on September 10 which was the day Ileana and Jack dissipated. Two day later the wave known as Invest 96B was upgraded into Tropical Depression Eleven. Eleven was later upgraded into Tropical Storm Katie, on Friday, September 13. Katie became a category 3 hurricane on September 16 and reached its peak of 165 mph on September 18 becoming the first Category 5 Hurricane in years it is currently at its current peak intensity of 185 mph sustained winds making it the strongest storm in history in the Bikini Bottom Region, it appears to still be getting stronger. It currently has maximum sustained winds of 200 mph and a central pressure of 860 mbars it is currently the strongest hurricane in Bikini Bottom's History it is currently curving back towards Bikini Bottom, where it is forecast to make landfall there as a strong Category 5 hurricane. A few hours later on September 22nd it now has maximum sustained winds of 200 mph. It currently doing a fujiwhara effect with the smaller and weaker Lee it is forecasted to absorb it into itself and rapidly become even stronger than it is now. Lee is now almost completely abosrbed into Katie so that one is about gone, but now it is engaging in a epic Fujiwhara effect. It now got stronger because Lee's eye and eyewall has merged with Katie's eye and eyewall it now has maxmium sustained winds of 210 mph, it is still engaging in a epic battle of dominance with Muriel. On September 22, all of Bikini Bottom was put under a hurricane warning. The convection of Katie and Muriel are now merged so now Muriel and Katie look like one hurricane with two well defined eyes Katie's eye is only 150-200 miles from Muriel's eye the merger between the two hurricanes is expected to be completed either later today or tomorrow or maybe as late as a few days from now, as both their eyes will merge with each other and it will become a monstrous very well defined crystal clear single eye and eyewall that would be twice the size of either of the seperate ones now. As Muriel began colliding into Katie, 60 knots of wind shear began to dominate Katie, halting intensification. Within hours, Katie had plummeted to a Category 3 hurricane as it beared down on Bikini Bottom because its entire northern quadrant was destroyed by wind shear. So far, seventy fatalities and $700 million (2013 USD) has been reported from Katie. It is no longer suffering from wind shear and it rapidly restrengthened into a Category 5 again. It is back to its former peak intensity of 225 mph it appears to be getting even stronger.

It has produced 200 tornadoes in and around the Bikini Botom Area about 95% of them were EF5 tornadoes and the other 5% were EF0 to EF4 tornadoes.

Current storm information
Citizens are advised to stay indoors, schools remain closed, and the Krusty Krab, as well as Mrs. Puff's Boating School, will both be closed until further notice. In a strongly worded public advisory, the Bikini Bottom Hurricane Warning Center claimed anyone outdoors in the approach of Katie would have a guaranteed death. Currently, Katie's eye is over all of Bikini Bottom.

Hazards:
 * 1) Gusts of up to 300 mph is now expected across Bikini Bottom.
 * 2) A storm surge of roughly 34 feet is still expected to indunate almost all of Bikini Bottom.
 * 3) Rainfall of 18 to 24 inches, possibly up to 48 inches, is expected in Bikini Bottom.
 * 4) Extremely heavy surf of roughly 100 feet or more is now expected in Goo Lagoon.
 * 5) Clustered tornadoes of up to EF5 intensity are expected around Bikini Bottom.

Hurrricane Lee
The Bikini Bottom Hurricane Warning Center began investigating a low-level circulation developing to the northeast of Katie; it quickly strengthened into Tropical Depression Twelve. A couple hours later, Twelve was upgraded into Tropical Storm Lee. Lee was forecast to bring severe flooding to Rina Bottom. It quickly became a hurricane with 80 mph sustained winds. Shortly afterwards, Lee further intensified to a Category 2 hurricane with maximum sustained winds of 110 mph. Around this time, the large outflow of Katie began affecting Lee, preventing any further intensification. The hurricane weakened to a low end Category 2 hurricane with sustained winds of 100 mph. By September 22, Lee had been absorbed into Katie's circulation.

Hurricane Muriel
Muriel formed from a tropical wave situated in between Katie and Lee on September 22, skipping tropical depression status and directly becoming Tropical Storm Muriel. As it moved away from Katie and Lee, Muriel attained winds of 60 knots (70 mph). Shortly afterwards, it became a Category 1 hurricane. Although Muriel was forecast to stay weak, it explosively intensified into a Category 5 hurricane within hours. Before long, it had maximum sustained winds of 205 mph and was engaging in a very notable Fujiwhara interaction with Katie. As the two hurricanes interacted, a dramatic surprise occured on September 24, when in just three hours, Muriel collapsed from a Category 5 hurricane all the way to a Category 1 system. Hours later, Muriel further collapsed to a tropical depression as Katie absorbed it, while passing over Rock Bottom. It is convection as of September 26th is now 100 miles from the center of circulation and it has upper level inflow instead of upper level outflow and a upper-level low to its east it has a slight chance of becoming a Subtropical Storm in the next several hours as it is presenting a better sattelite presenation by the hour, in fact it looks better than it did as a dissipating Tropical Depression maybe this is its second chance to strengthen again before becoming post-tropical, 2 to 3 days from now. It is now a Subtropical Storm because of improved satellite presentation and maxmium sustained winds of 50 mph it is forecasted to gradually gain tropical characteristics again before becoming a strong tropical storm again by tomorrow or the next day and maybe even become a hurricane again before becoming post-tropical but we will have to see. It is currently moving Southwest away from Hurricane Katie hopefully it wont get absorbed into Katie for good this time. It has made landfall again in Rock Bottom as a 45 mph Subtropical Storm at 8 a.m PDT causing a additional 4-8 inches of rain to fall over Rock Bottom. It is now a 70 mph Subtropical Storm and it is likely to become fully tropical again and regain hurricane status,as its outer band of convection has collapsed and refired over the the entire circulation center and it is very close to hurricane status again as a eye like feature is detected in current radar images. It is still subtropical at the moment but because of upper level outflow and the upper level low quickly dissipating it is likely to become a hurricane again at any moment because it has 80 mph sustained winds with it. It is now a hurricane again.

Muriel's explosive intensification triggered hurricane warnings for all of Rina and Rock Bottom. So far, one death, $10 million (2013 USD) in losses, and 103 tornadoes have been reported from the hurricane.

Current storm information
Hazards:
 * Gusts to 50 mph are still expected in Rock and Rina Bottom.
 * An estimated storm surge of 5 to 10 feet is expected to recede from all of Rock Bottom and Rina Bottom today.
 * Rainfall of 3 to 4 inches, possibly up to 8 inches in higher-elevated portions of Rina Bottom, is still expected across the islands.
 * Heavy surf is still occurring alongside the coasts in nearly all of Rock Bottom and the majority of Rina Bottom.
 * Clustered tornadoes of up to EF1 intensity tornados maybe even; isolated EF2 tornadoes are still expected in both Rock and Rina Bottom.

Hurricane Nestor
A tropical wave formed 300 miles to the east of Katie and Muriel in the afternoon hours of September 22; it skipped tropical depression status and directly became Tropical Storm Nestor. Nestor was forecast to strengthen only a little within the next few days; however, it unexpectedly became a major hurricane 125 mph Category 3 major hurricane. It is expected to make landfall in Shell City in the next 24-36 hours. It also decreased in forward speed from 24 mph to the west to 16 mph, which gave it more time to strengthen before it made a landfall in Shell City. However, a dramatic 50 knot (60 mph) wind shear increase around the Bikini Bottom region on September 23 destroyed nearly all of Nestor's convection, causing near rapid dissipation. Early the next day, Nestor was shredded into oblivion.

Even though hurricane warnings were issued for Shell City, Nestor's explosive weakening cancelled the warning and spared the region. As a result, no fatalities or damages were reported from Nestor.
