AREAS OF FOG HAVE DEVELOPED ACROSS THE AREA EARLY THIS MORNING.SOME OF THE FOG MAY BECOME LOCALLY DENSE, WITH VISIBILITY OF A QUARTER MILE OR LESS. DRIVERS SHOULD BE PREPARED FOR RAPIDLY CHANGING VISIBILITY. IF YOU ENCOUNTER DENSE FOG WHILE DRIVING, SLOW DOWN AND USE LOW BEAM HEADLIGHTS. LEAVE PLENTY OF SPACE BETWEEN YOU AND OTHER DRIVERS.
