ST. PETERSBURG — The Florida Highway Patrol is warning drivers to be careful on the roads Friday morning as a low, rolling sea fog settles over the coastal Bay Area.
Troopers said visibility is down to a quarter of a mile or less from Pinellas Point Drive to the Dick Misner Bridge in St. Petersburg.
Ernie Jillson, a National Weather Service meteorologist, said the fog rolled in Thursday night over the Gulf, and it's slowly moving over areas along the coast.
It's a result of warm, humid air moving over the gulf waters, Jillson explained. Along with lingering rain, that could make dangerous driving conditions.
"Use low beam headlights," Jillson said. "Slow down."
Unlike fog that settles over land, sea fog won't necessarily dissipate with daybreak. But Jillison said a cold front moving through from the north with drier air will help break it up by about 1 p.m.
Bay News 9 meteorologist Diane Kacmarik said the rain should clear up about the same time, with temperatures in the 70s expected for the rest of the afternoon.
