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.
Hurricane Agnes tornado outbreak
On June 18, a tornado touched down around 4:13 p.m. (EDT) near Fort Denaud, which is located near LaBelle in Hendry County. The tornado, killing one person, destroyed a truck and a trailer. The funnel also prostrated citrus trees and caused six injuries near LaBelle. Ten mobile homes were destroyed in two mobile home parks. In all, the tornado affected three mobile home parks and inflicted $200,000 (1972 USD) in property damage. Another tornado, occurring around 10:55 p.m. (EDT), destroyed 50 mobile homes and one fish camp near Okeechobee. This event killed six people and caused damage along a path that reached a width of 100 yards (0.05 mi). These tornadoes were operationally classified as "windstorms" in the official National Weather Service database, which indicated severe thunderstorm winds were responsible for the seven deaths. However, newspaper reports did cite the Okeechobee event as a tornado. Subsequently, an independent case study of the Hurricane Agnes outbreak in 1998 unveiled evidence that the events were two strong (F2–F3) tornadoes. However, the official database still lists the original number of tornadoes.
There were two unconfirmed tornadoes in Collier County. A brief tornado reportedly damaged a roof and two planes in the town of Immokalee. Power lines were downed in the area. Another possible tornado affected Everglades City, where trees were prostrated and portions of a home were transported for 0.25 mile (0.4 km). Lee County was affected by three F2 tornadoes, while an F1 tornado touched down in Seminole County. In all, the tornadoes in Lee, Seminole, and Brevard counties produced damages in excess of $100,000 (1972 USD).
Agnes produced a total of 8–11 strong (F2–F3) tornadoes in Florida. The accuracy of the ratings for many strong tornadoes in the 1950s, 1960s, and 1970s has been questioned by some authorities. Thomas P. Grazulis states that his criteria yielded fewer strong tornadoes than the official records. The author cites only four strong tornadoes for the Hurricane Agnes tornado outbreak. Only one F3 tornado is listed, while three F2 tornadoes are included in the analysis. The official database lists six F2 events and two F3 events.
