...A SNOW SQUALL WILL AFFECT NICHOLAS COUNTY...
At 120 AM EDT, a snow squall was located along a line extending from
7 miles east of Clay to near Richwood. Movement was south at 20 mph.
Winds in excess of 30 mph are possible with this squall.
Locations impacted include...
Summersville, Richwood, Craigsville, Calvin, Kesslers Cross Lanes,
Canvas, Muddlety, Nettie and Mount Nebo.
This includes Route 19 between mile markers 34 and 52.
Visibilities will drop quickly to less than a quarter of a mile in
this squall.
Use extra caution if you must travel into or through this dangerous
snow squall. Rapid changes in visibility and potentially slick roads
are likely to lead to accidents. Consider delaying travel until the
squall passes your location.
Temperatures well below freezing, in the teens to lower 20s, will
also lead to refreezing of melted snow on area roadways. Black ice
is nearly impossible to see and can also be hidden beneath snow.
Please use extreme caution, especially on bridges, overpasses and
around curves. Allow plenty of stopping distance and avoid braking
suddenly.
