Active AlertsNimrod Hall, VA

Partially clear skies, light winds and plenty of left over low- level moisture are helping areas of valley fog to develop and become dense early this morning. This fog will continue to expand through the rest of the night but likely will remain the densest in the valleys. Visibilities will be below a quarter of a mile at times in the thickest of fog. Be sure to slow down and use your low beam headlights when you encounter any fog
