A dense fog advisory is in effect for Tampa Bay this morning, and visibility is less than a quarter mile or less across most of the area.
Sea fog rolled in from the Gulf of Mexico yesterday evening and lingered throughout the night. Bay News 9 meteorologist Juli Marquez said it coupled with inland fog to prompt the National Weather Service's advisory, which will remain in effect until 10 a.m.
Tuesday marked the second day of heavy fog in Tampa Bay — and it's likely not the last, as forecasters say it's likely to repeat the next few mornings.
"There's so much moisture in the atmosphere that it's almost like nothing else can happen,'' said Mike Clay, Bay News 9's chief meteorologist.
The fog should be heaviest this morning and on Wednesday and Thursday mornings. The thickest will be sea fog on the Gulf of Mexico, pushed ashore by southwest winds. Sea fog forms as high humidity in the atmosphere collides with significantly cooler water temperatures, now in the high 50s along coastal areas of the gulf.
The Florida Highway Patrol issued a notice over the weekend ahead of the weather, urging caution and slower speeds when visibility is low.
Marquez said the fog will begin to dissipate by mid Tuesday morning; by afternoon it will be partly sunny and warm in most places.
"Most of us should make it to at least 80 degrees," Marquez said.
The beaches will be cooler Tuesday as fog moves out and a southwest wind moves in, Marquez said. Areas east of Tampa, on the other hand, could make it well into the 80s.
