Take steps now to protect tender plants from the cold.

Areas of dense fog will persist through 9 AM across extreme eastern Windham County in southern Vermont, adjacent to the Connecticut River. Visibilities may drop to or below one quarter of a mile in some areas. Motorists should use extra caution through 9 AM, and should anticipate significant reductions in visibility, including along portions of Interstate 91 near and north of Rockingham. Motorists should slow down and allow for extra braking distance, and use low beam headlights when encountering the fog.
