TAMPA -- Dense fog settled into the Bay area overnight, prompting an advisory for the entire region for Tuesday morning.
According to Bay News 9 meteorologist Juli Marquez, the dense fog advisory is in effect until 9 a.m.
"Visibility is down to a quarter of a mile or less in many locations," Marquez said. "In other spots, visibility is near zero."
Drivers are being advised to use caution this morning, and not to use their flashers.
Never miss a local story.
Using your flashers to be seen better by your fellow drivers during foggy or rainy conditions is actually against the law. Florida Highway Patrol Sgt. Steve Gaskins said engaging your flashers makes you less effective as a driver in fog or rain.
"The hazard lights, the amber hazard lights are equipped on vehicles are designed to indicate a stopped vehicle that is disabled on the side of the road," he said. "That's when those lights should be engaged."
According to Florida law, it is illegal to drive with the emergency flashers engaged. The reason is simple: Other drivers cannot see your turn signals when you are using your flashers.
Meanwhile, conditions remain cool this morning with a mild afternoon anticipated.
By this afternoon, temperatures will rise into the upper 60s with some low 70s.
A cold front will move through the Bay area tonight, bringing a chance of isolated showers and patchy fog.
