Dense fog will blanket parts of Tampa Bay through late Monday morning, leading into a muggy day, the National Weather Service reported.
Motorists should exercise extreme caution and be prepared to stop when driving on local interstates. Drive slower, use low-beam headlights and maintain extra spacing between vehicles.
Warm and humid air flowing over the cooler waters of the eastern Gulf of Mexico also has created areas of dense sea fog across Tampa Bay waters. Inexperienced boaters should take caution, especially with visibility under 1 nautical mile.
The fog is expected to break by 9 a.m., but in some parts of Tampa Bay it may linger.
Tampa Bay had all the right ingredients for fog: a light wind, lower temperatures and moisture close to the ground. The light breeze and cool air condense the moisture, which forms droplets in the air.
But the fog isn't a one-day event, said Bay News 9 meteorologist Juli Marquez.
"There will be areas of fog tomorrow, and a cold front will be coming," she said. "That could bring some chances of showers and cooler weather on Wednesday."
But for Monday, she said to expect temperatures in the mid-80s and upper 70s throughout the area.
