Patchy fog blanketed Tampa Bay early Monday, with less than a quarter mile of visibility reported in some areas.
A dense fog advisory was issued by the National Weather Service for several counties, including Hillsborough, Pinellas, Hernando and Pasco, on Monday morning.
The fog was expected to recede about 7 a.m., with some patchy areas lingering until about noon.
Sea fog was also reported along the coast, said Bay News 9 meteorologist Juli Marquez.
The Florida Highway Patrol also issued a weather warning for drivers traveling in Lakeland. The agency also warned drivers heading across the Sunshine Skyway Bridge overnight Sunday about visibility issues in that area.
The fog also delayed several vessels, including two cruise ships, on Sunday night at the Port of Tampa, said Daniel Grimes of port of operations Monday morning. The cruise ships were able to leave about 10 p.m. Sunday.
A Royal Caribbean cruise ship called Jewel of the Seas arrived at the port more than an hour late Monday morning due to the fog, said port spokesman Andy Fobes.
Temperatures on Monday morning will reach into the low 80s, Marquez said, with a 30 percent chance of rain.
A 70 percent chance of rain, including a few thunderstorms, was forecast for Tuesday.
A cold front was also expected to move into the area Tuesday, lowering temperatures into the low 70s in the afternoon and in the 50s on Wednesday and Thursday mornings, Marquez said. A stronger cold front will move into Tampa Bay over the weekend.
For the past several weeks, temperatures have fluctuated from warm to chilly conditions, but Marquez said the changing conditions were normal.
"This is the time of year where our temperatures can get very warm and very cold for several days," she said.
