...DENSE FOG ADVISORY IN EFFECT UNTIL 7 AM EST SATURDAY...
THE NATIONAL WEATHER SERVICE IN GREENVILLE-SPARTANBURG HAS ISSUED
A DENSE FOG ADVISORY...WHICH IS IN EFFECT UNTIL 7 AM EST
SATURDAY.
RECENT RAINFALL AND LIGHT WIND HAVE CREATED THE RIGHT CONDITIONS
FOR DENSE FOG TO DEVELOP ACROSS PARTS OF THE WESTERN CAROLINAS

ACROSS THE FOOTHILLS AND PIEDMONT OF NORTH CAROLINA AND UPSTATE
SOUTH CAROLINA. THE DENSE FOG WILL ALSO EXTEND INTO THE FRENCH
BROAD VALLEY AND THE NORTHERN MOUNTAINS. VISIBILITY WILL BE
REDUCED TO ONE QUARTER MILE OR LESS IN MANY LOCATIONS.
AS TEMPERATURES FALL LATE TONIGHT...SOME LOCATIONS MAY DIP DOWN TO
FREEZING BEFORE THE FOG DISSIPATES OR LIFTS. THIS COULD LEAD TO A
FREEZING FOG SITUATION DURING THE EARLY MORNING HOURS. IF THIS
HAPPENS...FOG DROPLETS COULD FREEZE ON CONTACT WITH COLD OBJECTS.
IN SOME SITUATIONS...THIS CAN RESULT IN SLIPPERY ROAD CONDITIONS.
THE FOG MAY LIFT OR THIN OUT IN THE PRE-DAWN HOURS...IN WHICH CASE
PORTIONS OF THE ADVISORY WILL BE CANCELLED. OTHERWISE...THE FOG
SHOULD LIFT JUST AFTER SUNRISE.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A DENSE FOG ADVISORY MEANS VISIBILITIES WILL FREQUENTLY BE
REDUCED TO LESS THAN ONE QUARTER MILE. IF DRIVING...SLOW DOWN...
USE YOUR HEADLIGHTS...AND LEAVE PLENTY OF DISTANCE AHEAD OF YOU.
