Meteorological HistoryEdit

Hurricane Terisa's Path

Terisa's Path

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.

Preparations and ImpactEdit

Northern Biolixi IslandEdit

The main impacts that were associated with Terisa would be the tremendous flooding. About 3 or so inches of rain were reported around the outside areas near Washington City. Flash flood and Flood warnings were issued throughout the Northern Biolixi Island. Six people were pronounced dead after Terisa had passed and left a large total of 11 inches of rain around the island. Terisa caused 200.3 million simoleons in damage.
