The combination of clear sky and light winds this morning has led to areas of locally dense fog developing, with visibility below a quarter of a mile at times. Motorists should use caution if out driving and be prepared for sudden changes in visibilities. Please allow for greater distances between vehicles and do not assume the road ahead is unobstructed. Use low beam headlights, and allow more time to reach your destination safely. The fog is expected to gradually lift and dissipate between 8 and 9 AM this morning.
