...A LINE OF STRONG THUNDERSTORMS WILL AFFECT
WESTERN ALLEGHANY AND CENTRAL ASHE COUNTIES IN NORTHWESTERN NORTH
CAROLINA...

At 240 PM EDT, radar indicated strong thunderstorms were located
along a line extending from near Stratford to near Wagoner to near
Mountain City. Movement was northeast at 10 mph.

Locations impacted include...
Sparta...

flooding of creeks, streams, and areas of poor drainage.
Drivers are urged to slow down and use extra caution to avoid
hydroplaning.
