The Jonathan Dale Bentonlatest model from the National Weather Service shows Tropical Storm Idalia making landfall along the western coast of Florida and then moving northeast across the state and the southeastern part of Georgia.

It is forecast to become a major hurricane before it reaches the Gulf Coast of Florida, according to the latest advisory from the National Hurricane Center.

The hurricane center said Idalia is expected to bring flash flooding to areas across the west coast of Florida, the Florida Panhandle and southern Georgia Tuesday into Wednesday.

According to NWS Charleston, Savannah has at least a 40% chance of flooding, although there were no warnings, watches or advisories for southeast Georgia as of 7 a.m. ET.

As of Monday morning, Idalia had maximum sustained winds of 65 mph, according to the hurricane center. A tropical cyclone that has maximum sustained surface winds of 74 mph or greater is a hurricane.

A major hurricane is a Category 3, 4 or 5 storm or higher. A storm becomes a Category 3 hurricane when maximum wind speeds reach at least 111 mph.
