The 2011 Biolixi hurricane season was an above average season that started on June 1 and ended on September 24: with a total of 22 tropical cyclones, 21 named storms, 13 hurricanes, and 8 major hurricanes. Many devestating systems formed during that this year; Isac was a particularly devestating category 5 storm that made landfall on the city of Coconut City. Other systems were devestating aswell, but didn't effect Simcity; Hurricanes Fred, Georgette, and Terisa proved to be disastrous storms to the Biolixi Islands. The total damage from this season is estimated at 42.4 billion simoleons; the deaths from this season are estimated at 4,079 and 66 are considered missing. The 2011 season was a quite strange season with an active start, yet an early end. Due to very strong La Nina in the ocean during the beginning of the season and an even stronger El Nino during the peak of the season. This season was expected to use the back up list, which are the names of the months, but due to that strong El Nino, the season strangely ended in September.


Seasonal Forecasts

The National Hurricane Center in Clark City predicted around 20 named storms, 10 hurricanes and 7 major hurricanes.

Actual Numbers:

Named Storms: 21

Hurricanes: 13

Hurricane Ana


Category 3 hurricane (SSHS)
Hurricane Ana.jpg Hurricane Ana's Path.jpg
Duration June 1 – June 10
Intensity 125 mph (205 km/h) (1-min),  968 mbar (hPa)

Main Article: Hurricane Ana (2011)

On May 28 an area of low pressure formed off the southern coast of of the Southern Biolixi Island. On June 1 the area of low pressure quickly gained momentum and became the very first tropical cyclone of the season, Tropical Depression One. Tropical Depression One then raced off to the Northeast toward the Eastern Biolixi Island; It quickly strengthened into Tropical Storm Ana on June 2. The tropcial storm then briefly turned into a category 1 hurricane before landfall on the Eastern Biolixi Island on June 3. Ana then weakened over land; but then moved out back into open water and quickly re-intensified into a tropical storm. Ana kept moving in a East-Northeast direction and intensified back into a category 1 hurricane on June 5. On June 7 Ana developed into a category 2 hurricane; in a period of just 19 hours it intesified into the first major hurricane of the season. The next day Ana moved into an area with wind shear; the storm quickly weakend into a category 2 and weakened further into a category 1. Ana soon weakened into a tropical storm and then into a tropical depression on June 9. Ana still remained a tropical depression and dwindled around a weak low pressure system; Ana then dissipated on June 10.

Hurricane Brett


Category 3 hurricane (SSHS)
Hurricane Brett.png Hurricane Brett's Path.png
Duration June 5 – June 13
Intensity 120 mph (195 km/h) (1-min),  960 mbar (hPa)

On June 1 a cold front spawned two areas of low pressure; one became Hurricane Ana and the other would soon become Hurricane Brett. The area of low pressure moved to the North-Northeast and started to gain tropical characteristics. On June 5 the area of low pressure developed into the second storm of the season, Tropical Depression Two. Two moved to the North-Northeast and soon intesified into Tropical Storm Brett on June 6. Brett continued its track to the North-Northeast and became a category 1 hurricane; the next day Brett became a category 2. Brett then came to a very small and weak area of low pressure; and due to northern wind shear, Brett rotated over and around the area of low pressure and began to head south. Heading south, Brett came into very warm waters and little no wind shear; Brett intensified into a category 3 on June 10. On June 11 Brett began to weaken; it weakened throughout the day and soon was a tropical storm by June 12. Brett then weakened into a tropcial depression and then dissipated on June 13.

Hurricane Celia

Category 2 hurricane (SSHS)
Hurricane Celia.jpg Hurricane Celia's Path.png
Duration June 8 – June 12
Intensity 100 mph (155 km/h) (1-min),  984 mbar (hPa)

On June 5 a line of thunderstorms that rocketed past London and developed an area of low pressure over land near the southern half of San Francisco Bay. The area of low pressure moved into the San Francisco Bay and developed into Tropical Depression Three on June 8. Tropical Depression Three intensified quickly into Tropical Storm Celia on June 9. Early on June 10 Celia became a category 1 hurricane and kept moving up San Francisco Bay; It briefly became a category 2 hurricane with maximum winds of 95 mph late on June 10. On June 11 Celia began its weakening process and weakened into a category 1 hurricane. Celia soon dissipated on June 12. Celia was a very devestating storm to the San Francisco Bay; Celia caused nearly 11.8 billion dollars in damage and caused 102 deaths. Celia also produced massive floods and even washed away many islands in the bay. Damage was widespread and devestating; it is estimated that clean-up will be completed in 2019.

Tropical Storm Doris


Tropical storm (SSHS)
Tropical Storm Doris.jpg Tropical Storm Doris' Path.png
Duration June 13 – June 15
Intensity 60 mph (95 km/h) (1-min),  995 mbar (hPa)

Main Article: Tropical Storm Doris (2011)

On June 11 an area of low pressure moved acroos the Biolixi Ocean and towards the Roanoke coast. On June 13 the area of low pressure developed into Tropical Depression Four; Later that day Three intenisfied into Tropical Storm Doris. On June 14 Doris made landfall in Roanoke with maximum minds of 60 mph; Doris then dissipated on June 15 due to high elevation further inland. Doris caused many deaths and produced several floods along the Roanoke Coast.

Tropical Storm Emma


Tropical storm (SSHS)
Tropical Storm Emma.png Tropical Storm Emma's Path.png
Duration June 15 – June 16
Intensity 55 mph (85 km/h) (1-min),  1000 mbar (hPa)

On June 14 a small and weak area of low pressure developed off the coast of Northwest. The National Hurricane Center forecasted that this system wouldn't form; but on June 15, Tropical Depression Five formed off the coast of Northwest Coast. The National Hurricane Center forecasted that it wouldn't intensify any further; but that same day Tropical Depression Five intensified into Tropical Storm Emma; Emma dissipated the next day on June 16. Emma traveled right along the coast of Northwest but didn't produce that much heavy rain and wind due to high wind shear in the area; but Emma did cause 3 deaths and 5 million simoleons in damage.

Hurricane Fred


Category 3 hurricane (SSHS)
Hurricane Fred.jpg Hurricane Fred's Path.png
Duration June 17 – June 21
Intensity 130 mph (205 km/h) (1-min),  955 mbar (hPa)

Main Aritcle: Hurricane Fred

On June 15 an area of low pressure formed to the south of the Eastern Biolixi Island. The low pressure area soon had an 80% chance of developing; but this created worry for many Biolixi Islands citizens. On June 17 the area of low pressure developed into Tropical Depression Six. Six traveled towards the Southern Biolixi Island, and on June 18 Six became Tropical Storm Fred. Fred moved West-Northwest towards the Southern Biolixi Island and became a category 1 hurricane later that day. Fred, approaching the coast briefly became a category 2 hurricane and made its first landfall in Marina City, Southern Biolixi Island. Fred then tracked North over the rest of the Southern Biolixi Island and weakened drasticaly into a weak tropical storm. Fred then moved back into water over the Sea of Biolixi; there Fred strengthened very quickly into a category 2 and then into the third major hurricane of the season. Many evacuations were ordered on the southern coast of the Northern Biolixi Island; Fred moved onshore early on June 20. Due to the high elevations of the island, Fred quickly weakened; Fred was downgraded into a tropical depression on June 21 and then dissipated the same day. Fred is considered the 5th most destructive Hurricane to strike the Biolixi Islands in history; with a total of 15.9 billion simoleons in damage and 1,300 deaths.

Hurricane Georgette


Category 4 hurricane (SSHS)
Hurricane Georgette.jpg Hurricane Georgette's Path.png
Duration June 19 – June 25
Intensity 150 mph (240 km/h) (1-min),  948 mbar (hPa)

Main Article: Hurricane Georgette

On June 17 an area of disturbed weather moving west, had developed a low pressure area. The National Hurricane Center gave the system a 90% chance of developing on June 18; on June 19, Tropical Depression Seven formed. On June 20 Seven intensified into Tropical Storm Georgette with winds of 60 mph. Even though Georgette was only a tropical storm at the time and due to the direction it was moving in, Georgette's possible major intensification lead to mandatory evacutations on the southeast coast of the Eastern Biolixi Island. On June 20 Georgette strengthened into a category 1 hurricane. The National Hurricane Center forecasted that Georgette could rapidly intensify before making landfall; because of their forecasts and that the fact that Georgette was now a hurricane, this lead to major evacuations of the southern portion of the Eastern Biolixi Island. Just as the National Hurricane Center forecasted, Georgette rapidly intensified into a major hurricane on June 21; and on that same day Georgette made landfall as a monster category 4 hurricane. Georgette continued to be a hurricane as it moved over high elevations of the Eastern Biolixi Island. Georgette was soon back over warm waters and strengthened back to a major hurricane and made its second landfall as a category 4 aswell on June 23. Late on June 23 Georgette began to weaken as dry air approached the system; Georgette weakened drasticaly into a tropical storm. Georgette briefly attained category 1 status but then quickly weakened; Georgette then dissipated on June 25. Georgette is considered the 3rd most devestating hurricane to strike the Biolixi Islands in history; with 17.6 billion simoleons in damage and nearly 2,000 deaths.

Tropical Storm Harvey


Tropical storm (SSHS)
Tropical Storm Harvey.jpg Tropical Storm Harvey's Path.png
Duration June 23 – June 26
Intensity 60 mph (95 km/h) (1-min),  997 mbar (hPa)

Main Article: Tropical Storm Harvey (2011)

On June 20 an area of low pressure centered about 404 miles northwest of Biolixi City, began to attain tropical characteristics. The area of low pressure began to move south towards Southwest; the National Hurricane Center gave the area of low pressure about an 80% chance of development in the next day or two. On June 23, Tropical Depression Eight had formed and continued to travel south. Later that day Eight quickly intensified into Tropical Storm Harvey; Harvey soon made landfall in Southwest with maximum winds of 60 mph. Harvey then weakened into a tropical depression; Harvey then dissipated on June 26. Harvey caused horrific and devestating floods in that region; totals from Harvey are 700 million simoleons in damage and 24 deaths.

Hurricane Isac


Category 5 hurricane (SSHS)
Hurricane Isac.jpg Hurricane Isac's Path.png
Duration June 27 – July 2
Intensity 175 mph (280 km/h) (1-min),  918 mbar (hPa)

Main Article: Hurricane Isac

On June 25 a vigorous low pressure system developed just west of the San Francisco Gulf; the low pressure system soon developed into Tropical Depression Nine on June 27. Nine only lasted 15 hours before becoming Tropical Storm Isac later that day. Isac soon sparked a potentialy dnagerous situation for the San Francisco Peninsula, according to the National Hurricane Center. The National Hurricane Center forecasted that Isac could become a major hurricane before possible landfall somewhere along the San Francisco Peninsula. Due to this possible threat manditory evacuations were ordered on June 28, when Isac became a category 1 hurricane. Hurricane Isac was heading east towards the coast over very warm waters and little to no wind shear was present; later that same day on June 28 Isac strengthened into a category 2. On June 29 Isac strengthened rapidly; Isac became a major category 3 hurricane and was heading East-Southeast towards Coconut City. Since Isac had become a major hurricane, mass evacuations were ordered for the San Francisco Peninsula, especially Coconut City. Early on June 30 Isac strengthened into a category 4 hurricane and was still continuing its dangerous path towards the San Francisco Peninsula; later that day right before its devestating landfall Isac became a category 5. Isac made landfall at Coconut City as a category 5; which brought imensely strong winds and very heavy rainfall. After making landfall Isac remained a hurriane onshore and then entered San Francisco Bay; Isac then made its second landfall on the eastern half of San Francisco as a category 1. On July 1 Isac weakened into a tropical storm over land; the next day on July 2 Isac weakened further into a tropical depression and then dissipated later that day.

Tropical Storm Jordan


Tropical storm (SSHS)
Tropical Storm Jordan.png Tropical Storm Jordan's Path.png
Duration July 5 – July 8
Intensity 60 mph (95 km/h) (1-min),  1002 mbar (hPa)

On July 4 a weak area of low pressure developed over open warm waters. The next day on July 5 the area of low pressure was upgraded to Tropical Depression Ten. Ten moved northeast and then intesified into Tropcial Storm Jordan on July 6. Jordan moved along a cold front and attained its peak intensity of 60 mph on July 7. The next day on July 8; Jordan weakened into a tropical depression and then dissipated the same day. Jordan did not affect any land, Jordan stayed out in open ocean its entire existance.

Tropical Depression Eleven


Tropical depression (SSHS)
Tropical Depression Eleven.png Tropical Depression Eleven's Path (2011).png
Duration July 11 – July 13
Intensity 35 mph (55 km/h) (1-min),  1007 mbar (hPa)

On June 30 a large tropical wave on the very western part of the Biolixi Ocean traveled west; the system traveled to the west for eight straight days, that's the longest lasting tropical disturbance in history. The disturbance soon developed an area of low pressure as it moved over warmer waters. On July 11 the area of low pressure developed into Tropical Depression Eleven. Eleven kept heading west for two days and on July 13, Eleven dissipated right off the coast of Frances Corner.

Hurricane Karen


Category 2 hurricane (SSHS)
Hurricane Karen.jpg Hurricane Karen's Path.png
Duration July 14 – July 20
Intensity 105 mph (165 km/h) (1-min),  971 mbar (hPa)

Main Article: Hurricane Karen (2011)

On July 13 a weak area of low pressure developed off shore of Northwest. The system dwindled in cold waters for a a few days; then on July 14 the disturbance gained strength and became Tropical Depression Twelve. Twelve was pushed around a weak high pressure system, afterwards Twelve strengthened into Tropical Storm Karen and moved qucikly to the northeast on July 16. On July 17 Karen came to an area of unusal warm waters with no wind shear; Karen then intensified into a category 1 hurricane. Hurricane Karen continued to move to the northeast but at a much quicker pace do to new wind shear in the area. On July 18 Karen intensified into a category 2 with maximum winds of 105 mph. Later that day on July 18 Karen began to weaken; it was downgraded into a category 1 very early on July 19. Later that same day Karen weakened into a tropical storm; and since Karen was now moving over colder waters, it further weakened into a tropical depression on July 20. Later that day Karen dissipated. Karen did not affect any land but did create strong rip currents along the Northwest coast, which claimed 2 lives.

Tropical Storm Larry


Tropical storm (SSHS)
Tropical Storm Larry.jpg Tropical Storm Larry's Path.png
Duration July 14 – July 21
Intensity 70 mph (110 km/h) (1-min),  990 mbar (hPa)

Main Article: Tropical Storm Larry (2011)

On July 13 a vigorous low pressure system headed east from Southwest. The low pressure system kept moving east and soon was above the Northern Biolixi Island and early on July 14 the System developed into Tropical Depression Thirteen. Thirteen raced across the Biolixi Ocean, moving East-Southeast. On July 15 Thirteen intensified into Tropical Storm Larry continuing to move East-Southeast. Larry kept moving in that direction and created a dangerous threat of rip currents to the Biolixi Islands. The National Hurricane Center forecasted that Larry would intensify into a hurricane, but due to below average temperatures Larry remained a tropical storm. Larry, contiuing its East-Southeast track, was moving closer to the Virginia coast; due to high wind shear along the Virginia coast Larry weakened to a tropcial depression on July 20. On July 21 Larry weakened to a very weak tropical depression and then dissipated later that day. Larry brought high surf to the Biolixi Islands and Virginia claiming 3 lives.

Tropical Storm Megan


Tropical storm (SSHS)
Tropical Storm Megan.jpg Tropical Storm Megan's Path.png
Duration July 21 – July 24
Intensity 45 mph (75 km/h) (1-min),  1003 mbar (hPa)

Main Article: Tropical Storm Megan (2011)

On July 20 a low pressure system was spawned off from a weakening Tropical Storm Larry. The low pressure system tracked North-Northeast; and eveloped into Tropical Depression Fourteen on July 22. Fourteen was forecasted to become a tropical storm, which it did later that day. Tropical Storm Megan, still moving North-Northeast entered the San Francisco Gulf with winds of 40 mph. The National Hurricane Center forecasted that Megan could strengthen rapidly due to very warm ocean temperatures; but since new wind shear entered the area Megan began to weaken. Late on July 22 Megan weakened back into a tropical depression. Tropical Depression Megan was still moving in a North-northeastern direction towards the Barrier Peninsula. The National Hurricane Center said that Megan would not strengthen, but could possibly bring high surf and a rip current threat; Megan made landfall as a tropical depression with winds of 30 mph on July 24. Later that day Megan dissipated over the San Francisco Bay. Megan claimed 4 lives and caused less than 1 million simoleons in damage.

Hurricane Nate


Category 1 hurricane (SSHS)
Hurricane Nate.jpg Hurricane Nate's Path.png
Duration July 21 – July 26
Intensity 90 mph (150 km/h) (1-min),  988 mbar (hPa)

Main Article: Hurricane Nate (2011)

On July 21 an area of low pressure centerd in between all three Biolixi Islands in the Sea of Biolixi was developing; later that day the disturbance developed into Tropical Depression Fifteen. Fifteen slowly moved northeast and intensified into Tropical Storm Nate on July 22 right off the coast of the Eastern Biolixi Island. Nate continued to move northeast and brought heavy rain to the very northwest portion of the Eastern Biolixi Island. Nate moved away from land and began to head East-Northeast and developed into a category 1 hurricane later that day on July 23. Late on July 24 Hurricane Nate changed direction and began to move east because of a steering high pressure system. The National Hurricane Center forecasted Nate to strengthen, but due to wind shear Nate remained a category 1 hurricane. On July 25 Nate began to weaken and head south; Nate was downgraded to a tropical storm late that same day. On July 26 Nate weakened into a tropical depression and dissipated later that day. Nate brought high surf to the Biolixi Islands and caused flooding to the Eastern Biolixi Island; Nate altogether caused 1 million simoleons in damage and claimed 5 lives.

Hurricane Otto


Category 5 hurricane (SSHS)
Hurricane Otto.jpg Hurricane Otto's Path.png
Duration July 21 – July 29
Intensity 185 mph (295 km/h) (1-min),  909 mbar (hPa)

Main Article: Hurricane Otto (2011)

On July 19 a weak stalling area of subtropical weather was developing; on July 20 the system began to head southwest and started to gain tropcial characteristics. On July 21 the system developed into Tropical Depression Sixteen. Sixteen was forecasted to rapidly intensify by the National Hurricane Center; later that day Sixteen strengthened into Tropical Storm Otto. Otto continued to move southwest towards Southwest. Later in the day on July 22 Otto strengthened into the nineth hurricane of the season. Otto was still forecasted to rapidly intensify and possibly hit Southwest; on July 23 Otto strengthened int oa category 2 hurricane. Stiil moving in a southwest direction, Otto continued to rapidly intensify; on July 24 Otto strengthened into a major hurricane and shifted towards the west-southwest. Due to Otto's intensification and shift in direction this lead to manditory evacuations along the Southwest coast. On July 25 Otto began to come closer to the coast; it strengthened into a category 4 later that day, this triggered complete evacuations along the Southwest coast. Continuing its dangerous track, Otto came closer to the coast bringing heavy rain and strong gusts of wind; the National Hurricane Center forecasted Otto to strengthen into a category 5 before possible landfall in Southwest close to Orange City. On July 27 Otto strengthened into a category 5 bringing even more damage to the coast; but due to a high prssure system, Otto was steered away from the coast and to the northwest. After making a sharp turn to the west-northwest Otto began to weaken very drastically because of high wind shear. On July 28 Otto weakened down to a tropical storm with winds of 45 mph, and on July 29 Otto weakened into a tropical depression and then dissipated later that day. Otto caused 950 million simoleons in damage and caused 31 deaths; even though Otto created lots of damage and deaths, the name "Otto" was not retired by the National Hurricane Center.

Tropical Storm Peter


Tropical storm (SSHS)
Tropical Storm Peter.png Tropical Storm Peter's Path.png
Duration August 3 – August 7
Intensity 50 mph (85 km/h) (1-min),  999 mbar (hPa)

On August 1 a weak low pressure system tracked across the northern-teer of the Biolixi Ocean. The system was forecatsed to merge with a low that was place infront of the disturbance; but the system dissipated and allowed time for the low pressure system to develop. On August 3 Tropical Depression Seventeen formed over cold waters, which is very rare. Seventeen moved east-northeast and was forecasted by the National Hurricane Center to dissipate due to cold waters; but the system continued to gather strength. On August 5 Seventeen intensified into Tropical Storm Peter with winds of 45 mph, Peter attained peak winds of 50 mph later that day. Peter soon gradually began to fall apart due to how arctic air was being pushed down on top of the storm, and due to winds shear by several lows. Peter soon tracked northwest and weakened into a tropical depression on August 6 and then dissipated the next day on August 7. Peter layed many records down in the record book; Peter is considered the coldest tropical cyclone to have ever formed. But that title was changed after the colder formation of Hurricane January in 2012.

Hurricane Rylee


Category 2 hurricane (SSHS)
Hurricane Rylee.jpg Hurricane Rylee's Path.png
Duration August 9 – August 14
Intensity 110 mph (175 km/h) (1-min),  970 mbar (hPa)

Main Article: Hurricane Rylee (2011)

On August 8 a vigorous low pressure system developed; the system tracked north and on August 9 the disturbance became Tropical Depression Eighteen. Eighteen continued north and strengthened; on August 10 Eighteen became Tropical Storm Rylee. The National Hurricane Center forecasted that Rylee would rapidly intensify, Rylee almost accomplished rapidly intensifying, Rylee instead continued to be tropical storm for the remainder of the day. On August 11 Rylee became a category 1 hurricane and began to shift to the north-northeast. Rylee continued to strengthen throughout the day and became a category 2 on August 12; Rylee attained its peak intensity of 110 mph that same day. The next day on August 13 Rylee began to rapidly weaken due to wind shear; the system was pushed to the east and weakened into a tropical storm; Rylee then began to curve to the northeast and then weakened into a tropical depression. On August 14 Rylee dissipated. Many hurricane tracking companies argued that Rylee became a category 3 hurricane with maximum winds of 120 mph; but the National Hurricane Center disagreed because of how high the pressure was and that the fact it was in a state of shear.

Hurricane Sandra


Category 4 hurricane (SSHS)
Hurricane Sandra.jpg Hurricane Sandra's Path.png
Duration August 25 – September 5
Intensity 140 mph (220 km/h) (1-min),  937 mbar (hPa)

Main Article: Hurricane Sandra (2011)

On August 15 a tropical wave formed on the very western side of the Biolixi Ocean. The wave traveled steadily across the ocean until it reached, roughly to north of the very center of the Biolixi Ocean. The disturbance soon began to gain tropical characteristics and became Tropical Depression Nineteen on August 25. Nineteen continued to move to the east towards Roanoke; Nineteen began to strengthen due to lack of winds shear in the area. On August 26 Nineteen intensified into Tropical Storm Sandra, the eighteenth named storm of the season. Sandra soon was gradually beginning to be pulled around a weak area of high pressure; Sandra was still continuing west and dipped a little south due to the high pressure system above it. Sandra became a category 1 hurricane on August 27; Sandra, still gaining strength was now beginning to be pushed around the system next to it, Sandra began to head to the northeast. On August 28 Sandra strengthened into a category 2 hurricane and then quickly into a category 3; Sandra now was beginning to move to the north. On August 29 Sandra became a category 4 major hurricane with maximum winds of 140 mph and pressure at 937 mbar. With the high pressure system still next to Sandra, Sandra zoomed to north very quickly, still maintaning its strength, and was now moving to the northwest. On September 1 Sandra began its weakening process and weakened into a category 3. On September 2 Sandra weakened into a category 2, and on September 3 Sandra weakened into a category 1. On the same day Sandra weakened into a tropical storm. On September 4 Sandra weakened into a tropical depression and then disspated the next day due to colder waters. Sandra brought very strong rip currents to the Roanoke coast which killed 4 people.

Hurricane Terisa


Category 3 hurricane (SSHS)
Hurricane Terisa.jpg Hurricane Terisa's Path.png
Duration September 1 – September 10
Intensity 120 mph (195 km/h) (1-min),  958 mbar (hPa)

Main Article: Hurricane Terisa (2011)

On August 30, a large tropical wave emerged off of Southwest. The large system tracked over very warm waters near the Biolixi Islands; the National Hurricane Center gave the system a 90% chance of developing. The next day, the system intensified into Tropical Depression Twenty with winds of 35 mph. On September 2, Twenty became Tropical Storm Terisa and made landfall on the Northern Biolixi Island. When Terisa made landfall, it caused several floods and brought heavy rains, especially to Washington City. Terisa weakened over the landmass, but then tracked out over warm waters again; Terisa then strengthened into a tropical storm. Terisa became a category 1 hurricane on September 4 and began to turn to the northeast. Because of unusually low presence of winds shear, Terisa became a category 2. As Terisa began its move to the north, Terisa became the eighth major hurricane of the season with maximum sustained winds of 120 mph and pressure at 958 mbar. On September 7, Terisa began its weakening process and began to curve off to the northwest; Terisa wekened into a category 2 that day. Strong wind shear pushed the system to the northwest at a very fast speed on September 8; Terisa weakened into a category 1 and then a tropical storm. Terisa weakened into a tropical depression and then dissipated on September 10. Terisa only caused damage to the Northern Biolixi Island with moderately strong winds and widespread flooding; Terisa also caused rip currents to the island because of its size and strength.

Tropical Storm Viki


Tropical storm (SSHS)
Tropical Storm Viki.png Tropical Storm Viki's Path.png
Duration September 17 – September 19
Intensity 65 mph (100 km/h) (1-min),  992 mbar (hPa)

Main Article: Tropical Storm Viki (2011)

On September 15, a stalling tropical wave formed in the Gulf of San Francisco. The system stayed near the western part of the gulf and was moving near 3 mph. The slow moving system was given a 90% chance of development by the National Hurricane Center; they said that since the system is stalling over warm waters, it could possibly develop and intensify into a hurricane. Many people in San Francisco evacuated even though no mandatory evacuations were ordered; no one wanted to experiance another major hurricane since Hurricane Isac destroyed the coastline earlier that year. On September 16, Tropical Depression Twenty-One formed and was now moving to the east towards the San Francisco coast. The same day, Twenty-One developed into Tropical Storm Viki; duw to stronger wind shear in the area, Viki was now forecasted to only strengthen into a category 1 before landfall. On September 17, Viki approached the coastline and was now forecasted to only stay a tropical storm during landfall. Viki made landfall on the San Francisco Peninsula near Tree Beach with winds of 65 mph and pressure at 992 mbar. After landfall, Viki began its weakeneing process. The strong windshear and mountainous terrian made it very difficult for Viki to regain any strength. Viki returned over water in the San Francisco Bay on September 19, made landfall, and then dissipated. Viki caused widespread flooding to San Francisco and gusty winds; Viki in all caused 150.8 million simoleons in damage and killed 1 sim.

Hurricane William


Category 1 hurricane (SSHS)

Duration September 23 – September 26
Intensity 80 mph (130 km/h) (1-min),  988 mbar (hPa)

Main Article: Hurricane William (2011)

On September 20, a low pressure system merged with a cold front creating a tropical low. The National Hurricane Center gave the system a 70% chance of developing. On September 23 the final system of the 2011 Biolixi Ocean hurricane season formed. Tropical Depression Twenty-Two moved slowly towards the Roanoke coast. The next day on the 24th, Twenty-Two became the final named storm of the season, William. William tracked steadily towards the coast with 60 mph winds; the National Hurricane Center forecasted the system to only stay a tropical storm due to a merging low infront of the system. Unmandatory evacuations were ordered on the Roanoke coast. Later that day on September 24, William strengthened into a category 1 hurricane. On September 25 mandatory evacuations were ordered:William made landfall later that day. William soon weakened into a tropical storm, then a depression, and soon dissipated on September 26. William added to the amount of flooding caused by Tropical Storm Doris earlier that year; William caused 300.9 million simoleons in damage and killed 14 sims.
