Florida's west coast is under a storm surge warning with danger of life-threatening conditions, especially from Fort Myers to the Tampa Bay region. By late Tuesday, tropical storm conditions are expected to arrive in Florida, with hurricane-force winds starting in west-central Florida on Wednesday morning.

Florida Keys and south Florida will experience heavy rainfall on Tuesday, spreading to central and northern Florida over Wednesday and Thursday. This can trigger flash, urban, and small stream flooding.

Central Florida may endure significant prolonged river flooding. Tornadoes are possible late on Monday and Tuesday across the Florida Keys and the southern/central Florida Peninsula.

The Southeast U.S. will face heavy rainfall Friday and Saturday. Central and northern Florida, southern Georgia, and coastal South Carolina should prepare for widespread considerable flash and urban flooding, and prolonged significant river flooding in the mid-to-late week.

Rainfall may provoke flash and urban flooding across the Florida Keys and the Florida peninsula through mid week.

How to find updated flood risk maps

At least 1.5 million properties are at risk of flooding in case of even a category 1 hurricane, according to the Tampa Bay Times. Some experts suggest the number could be much higher, as many flood threat maps are largely outdated.
