Idalia is currently forecast to make landfall along Florida’s Big Bend region between Apalachicola and Tampa as a Category 3 hurricane. If this happens, it will mark the strongest landfall for the Big Bend region since 1950, when Category 3 Hurricane Easy made landfall in Cedar Key.
No hurricanes have ever made landfall in the Big Bend region stronger than Category 3.
If Idalia makes landfall as a Category 2, it will be the first in the region since Gladys in 1968.

Schools in Hillsborough County, which encompasses Tampa, will also be closed Tuesday and Wednesday.
