...A LINE OF STRONG THUNDERSTORMS WILL AFFECT SOUTHWESTERN
ROCKBRIDGE...BEDFORD...CENTRAL BOTETOURT AND NORTHEASTERN FRANKLIN
COUNTIES...

At 1259 PM EDT, radar indicated strong thunderstorms were located

Mount. Movement was southeast at 10 mph.

Locations impacted include...
Bedford...
Rocky Mount...
Buchanan...
Stewartsville...
Moneta...
Penhook...
and Montvale.

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. This includes Interstate 81 especially between mile
markers 160 and 180.

Frequent cloud to ground lightning is occurring with these storms.
Lightning can strike 10 miles away from a thunderstorm. Seek a safe
shelter inside a building or vehicle.
