...A SNOW SQUALL WILL AFFECT SOUTHERN CALHOUN...SOUTHWESTERN
RANDOLPH...SOUTHWESTERN POCAHONTAS...NORTHEASTERN NICHOLAS...SOUTHERN
BRAXTON...ROANE...WEBSTER AND NORTHERN CLAY COUNTIES...
At 1218 AM EDT, a snow squall was located along a line extending from
near Spencer to 10 miles east of Addison (Webster Springs). Movement
was southeast at 25 mph.
Winds in excess of 30 mph are possible with this squall.
Locations impacted include...
Spencer, Marlinton, Sutton, Clay, Webster Springs, Gassaway, Addison
(Webster Springs), Camden-On-gauley, Birch River, Big Otter, Camden
On Gauley, Wallback, Amma, Harrison, Cowen, Nebo, Rosedale, Upper
Glade, Waneta and Boggs.
This includes the following highways...
Interstate 79 between mile markers 22 and 63.
Route 19 between mile markers 51 and 68.
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 lower to mid 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.
