…AREAS OF FOG DENSE IN PLACES…

CLEAR SKIES AND LIGHT WINDS HAVE ALLOWED THE TEMPERATURE TO DROP RAPIDLY OVERNIGHT. AREAS OF FOG HAVE FORMED…ESPECIALLY IN LOW LYING AREAS AND IN RIVER VALLEYS…WITH VISIBILITY REDUCED TO UNDER ONE QUARTER MILE IN A FEW LOCATIONS. PATCHY DENSE FOG IS MOST WIDESPREAD SOUTH OF U.S. HIGHWAY 20. MOTORISTS SHOULD BE
AWARE OF THE POSSIBILITY OF SUDDEN VISIBILITY CHANGES AND ALLOW FOR EXTRA TRAVEL TIME TO REACH THEIR DESTINATION.

THE FOG WILL BEGIN LIFTING SHORTLY AFTER SUNRISE AND DISSIPATE BY MID MORNING.
