...A LINE OF STRONG THUNDERSTORMS WILL AFFECT SOUTHWESTERN MOORE...
NORTHERN ANSON...SOUTHERN MONTGOMERY...NORTHERN RICHMOND AND SOUTHERN
STANLY COUNTIES UNTIL 800 PM EDT...

At 703 PM EDT, Doppler radar was tracking a line of strong
thunderstorms along a line extending from near Unionville to near
Pinehurst. Movement was west at 10 mph.

Heavy rain and minor flooding will be possible with these storms.

Locations impacted include...
Southern Pines, Pinehurst, Aberdeen, Ansonville, Whispering Pines,
Norwood, Oakboro, Stanfield, Pinebluff and Mount Gilead.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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, especially in urban areas where prolonged heavy rain
can quickly lead to flooding.
