Effects of Hurricane Irma in Florida
Irma was the first major hurricane to strike the state since Wilma in 2005 and the first Category 4 hurricane to make landfall in Florida since Charley in 2004. The storm made landfall in Florida on the same date as Hurricane Donna, the last Category 4 hurricane to strike the Florida Keys. Irma was only the second hurricane to hit Florida since Wilma, the other being Hermine in 2016. Due to few very intense hurricanes since Hurricane Andrew in 1992, there was concern that many Floridians never experienced or did not recall experiencing a hurricane as strong as Irma was projected to be at landfall, with significant growth in population and assets during the previous 25 years.
Meteorological history of Hurricane Andrew
The meteorological history of Hurricane Andrew, the strongest tropical cyclone of the 1992 Atlantic hurricane season, lasted from mid to late August 1992. The hurricane developed from a tropical wave that moved off the coast of Africa on August 14. Tracking westward due to a ridge, favorable conditions allowed it to develop into Tropical Depression Three on August 16 in the deep tropical Atlantic Ocean. The cyclone gradually intensified, becoming a tropical storm on August 17. However, wind shear soon impacted the storm, causing significant increases in barometric pressure and nearly destroying its low-level circulation by August 20. Wind shear sharply decreased starting on August 21, and with warm sea surface temperatures, Andrew began rapid deepening, starting on the following day. By August 23, Andrew peaked as a Category 5 hurricane on the Saffir–Simpson hurricane wind scale while approaching The Bahamas.
