"Francine will likely become a hurricane today, with significant strengthening expected before it reaches the coast," the National Hurricane Center said.

Tropical Storm Francine has become better organized, with a central dense overcast and increased convective banding observed near the center. The central pressure has also dropped, indicating potential for strengthening.

Heavy rain, a threat for tornadoes and gusty winds are in store for Florida's Panhandle as Francine moves north. For Polk? NWS is watching the rivers.
