Dense fog advisory issued for parts of Miami-Dade and Broward counties

Dense fog is developing across parts of South Florida early Wednesday — and forecasters are asking drivers to be careful.

The National Weather Service has issued a special weather advisory, warning drivers about the possible hazardous driving conditions they might experience across inland Miami-Dade and Broward County during the early morning rush hour.

Forecasters say drivers could have “less than one quarter mile” of visibility on the road, especially near the Everglades along Interstate 75. The worst of the fog might be across Alligator Alley, said NBC6 meteorologist Adam Berg.

Some areas expected to have foggy driving conditions at least until 9 a.m. include Homestead, Florida City, West Kendall and the area around the Everglades. Those who live in Glades, Hendry, inland Palm Beach and Collier counties are also under a dense fog advisory.

Forecasters say foggy driving conditions will also be possible over the interior and western areas late Wednesday and into early Thursday, with visibility dropping to less than one quarter of a mile.

Drivers should turn on their low-beam lights, drive slowly and “leave plenty of distance ahead of you,” the weather service says. Drivers should also be cautious and watch out for pedestrians and other vehicles.
