HIDE Special Weather Statement issued October 03 at 5:28AM EDT by NWS Blacksburg
...Areas of fog this morning...
Fog has developed in the mountain valleys and along area rivers
and lakes this morning. The visibility in some locations was less
than one-half mile. The fog is expected to linger through mid
morning before dissipating.
Use caution when traveling. Slow down and allow extra time to
reach your destination.
When driving use low beam headlights, and leave plenty of space
between you and the vehicle in front of you. Keep in mind it is
also difficult to see animals crossing the road in foggy
conditions, so reducing your speed will help avoid collisions.
