Dense fog advisory extended in Miami-Dade and Broward. Here’s what it means for you

Miami-Dade and Broward County’s dense fog advisory has been extended until at least 11 a.m. Tuesday and is causing “very hazardous” driving conditions across South Florida, according to the National Weather Service.

Some areas began reporting “near zero visibility” shortly before morning rush hour, according to forecasters. The area around Homestead has the “greatest dense fog,” as of 9:30 a.m., according to the weather service.

Advisories are also in effect for southern inland Collier and mainland Monroe County, according to the hazardous weather outlook. Palm Beach County’s dense fog advisory was lifted at 9 a.m.

The roadways were covered in thick patches of fog early Tuesday, making it difficult to drive along highways and roads, including main streets such as Bird Road, Coral Way and Doral.

“Dense fog [is] producing sudden visibility drops to 1/4-mile to near-zero visibility across South Florida across portions of South Florida this morning,” the National Weather Service in Miami tweeted. “The sudden visibility drops are creating very hazardous conditions for traveling.”

Forecasters are asking drivers to slow down and watch out for stopped or slow-moving cars. The dense fog could cause delays during morning rush hour.

Drivers are asked to turn on low-beam headlights instead of high-beam headlights to drive through the thick fog. You should also turn on your windshield wipers to help increase visibility.

Don’t use your phone, concentrate on the road and pull over if the fog gets too thick.
