...A LINE OF HEAVIER SHOWERS WILL AFFECT NORTHEASTERN ALLEGHANY
COUNTY IN NORTHWESTERN NORTH CAROLINA...SOUTH CENTRAL
WYTHE...SOUTHWESTERN CARROLL AND EASTERN GRAYSON COUNTIES IN
SOUTHWESTERN VIRGINIA AND THE CITY OF GALAX...

At 814 AM EDT, radar indicated an area of heavier showers located
from near Cripple Creek to near Low Gap. Movement was southeast at
15 mph.

Rainfall rates of 1 to 2 inches an hour, will likely cause ponding
of water issues especially in the city of Galax through 900am.

Locations impacted include...
Galax...
Fries...
Ennice...
Cripple Creek...
Baywood...
and Spring Valley.

Locally heavy rain will quickly reduce visibility and result in
ponding of water on roadways, standing water in low lying areas, and
minor flooding of creeks, streams, and areas of poor drainage.
Drivers are urged to slow down and use extra caution to avoid
hydroplaning.
