TAMPA, Fla. (WFLA) — Tropical Storm Debby is expected to become a hurricane before it hits landfall in the Big Bend of Florida early Monday, according to the National Hurricane Center.

In an 11 a.m. update, the NHC said the storm is continuing to strengthen as it approaches the state, showing maximum sustained winds of 65 mph. A major flood threat is looming over the state.

Forecasters anticipate the storm to become Category 1 hurricane strength as it makes landfall in the Panhandle around St. Marks.

As the storm moves north, with a gradual turn to the right along the west coast, heavy winds and rainfall are to be expected. The lower Florida Keys and Southwest Florida are already being hit with the outer rainbands of the storm.

The Tampa Bay area is currently under a storm surge watch and rain is expected Sunday afternoon. Florida's Big Bend is bracing for heavy rainfall and flooding and is under a storm surge warning.

The track shows a rain potential of 6 to 12 inches, with a maximum potential of 18 inches through Thursday for Florida.

"Hide from the wind, run from the water," Governor Ron DeSantis said in a press conference Sunday morning.

DeSantis also advised Floridians to stay prepared with storm essentials and to bring all outdoor items inside so any debris doesn't harm your home or others.

After landfall, the NHC said the system is expected to slow down and turn northeastward towards Georgia on Monday and Tuesday.
