HIDE Special Weather Statement issued July 06 at 6:43AM EDT by NWS Blacksburg
...Patchy Dense Fog to Hamper Morning Commute...
Within the last few hours, patchy dense fog has developed across
much of the region as a result of mostly clear skies overnight,
near calm winds, and high relative humidity values. Visibilities
vary widely across the forecast area from one location to another
with some valleys and areas adjacent or near bodies of water,
creeks, streams, or rivers subject to dense fog, while other
locations at higher elevations and in more urban city areas tend
to see little or no fog.
Note, patches of dense fog will be found along portions of
Interstate 77, Interstate 81, and Interstate 64.
As you travel about the area this morning, be alert for rapidly
changing visibility in fog from one location to another. When you
find yourself in an area of dense fog, reduce speed, allow extra
distance between you and the vehicle in front of you, and use your
low beam headlights.
All of the fog should dissipate by 9 AM EDT this morning.
