A dense fog caused dangerous driving conditions in South Florida due to lack of visibility Tuesday morning.
The fog reduced visibility to less than one quarter mile for drivers traveling in Broward, Palm Beach, Miami-Dade and the Florida Keys. There were some reports of near zero visibility.
U.S. 27, also known as Okeechobee Road, remained closed from South Bay in Palm Beach County to Interstate 75 in western Broward since 2:30 a.m., according to the Florida Highway Patrol.
Authorities advice drivers slow down, use low beam headlights, and leave plenty of distance between other vehicles.
Officials are asking travelers in South Florida to also check the status of their flights. Delays have been reported at Miami International Airport and Palm Beach International Airport. Nearly 30 flights have been canceled in Palm Beach as of 6 a.m., because of a northern snow storm.
The National Weather Service's dense fog advisory was in effect in South Florida until 9 a.m. Light winds and low level moisture to the south of a strong cold front moving across Central Florida caused the fog.
Tuesday's weather calls for a partly sunny day with highs in the low 80s during the day, and lows in the upper 50s inland at night, said meteorologist Lissette Gonzalez.
Overnight, a cool front will settle in, causing temperatures to feel like it's in the high 30s to low 40s, during early Wednesday and Thursday.
