Areas of fog this evening
Areas of fog will restrict the visibility this evening. Visibilities of 1 mile or less are expected. Patchy dense fog with visibility of a quarter mile or less is possible near the Blue Ridge, impacting Interstate 81 near Christiansburg mountain, and along interstate 77 near Fancy Gap.
The visibility is expected to improve by midnight as rain overspreads the region. The rain should allow the fog to lift, however rain and wet roads will become an additional hazard to compensate for, during the overnight.
Regardless of the impinging weather hazard, please use caution if traveling. Slow down and allow plenty of room between you and the vehicle in front of you. Greater braking distance is required when roads are wet and the visibility is poor.
