Foggy weather grounds airplanes, causes travel delays across South Florida

Dense fog descended on South Florida Wednesday morning as many South Floridians began heading to their Thanksgiving destinations, delaying flights and creating dangerous road conditions on an already strenuous day of travel.

Miami International Airport held all inbound flights until 10 a.m., citing the foggy conditions. Inbound flights are currently experiencing delays of over an hour, while flights out of the airport were experiencing delays of 35 minutes and increasing, as of 10:30 a.m.

Flights out of Fort Lauderdale Airport had average delays of 25 minutes and increasing.

Air travelers are reminded to check with their carriers or flightaware.com before heading to the airport in case there are delays.

Those who took to the roads early Wednesday morning also had a slow — and hazardous — start due to the fog.

The National Weather Service Miami issued a dense fog advisory for drivers in Broward and Palm Beach counties, which had the lowest visibility, until 8 a.m.

“Use caution when driving! Keep your eyes out and slow down,” the weather service said.

A fatal multi-vehicle crash on the Florida Turnpike in Boca Raton a little before 7 a.m. Wednesday shut down all northbound lanes, according to Florida Highway Patrol. Lanes remained closed as of 10:30 a.m.

The fog had dissipated by late morning. Forecasters predict warm, partly cloudy weather through the rest of the week.
