MIAMI (AP) - Foggy conditions are making driving difficult for some motorists across South Florida.
Authorities closed U.S. 27 from South Bay in Palm Beach County to Interstate 75 in Broward County around 2:30 a.m. Tuesday because of heavy fog. It was unclear how long the road would be closed.
The National Weather Service issued a dense fog advisory until 9 a.m. Tuesday. In some areas, visibility is reduced to a quarter mile or less.
Drivers are urged to slow down and use low-beam headlights.
