ST. GEORGE ISLAND, FL (AP) - Parts of the main interstate highway across northern Florida are closed due to flooding as Tropical Storm Debby threatens up to two feet of rain in the region.

After raking Florida's Gulf coast with high winds and heavy rain, Debby promised to bring more of the same Tuesday as it moves slowly on a path forecast to take it over the state and into the Atlantic by Friday.

The National Hurricane Center said Debby was about 85 miles west of Cedar Key, Fla., and moving eastward near 3 mph. It had maximum sustained winds near 45 mph.

The Florida Highway Patrol closed portions of Interstate 10 in north Florida early Tuesday due to flooding and warned motorists to use extreme caution on other parts of the highway.
