...AN AREA OF SHOWERS AND STRONG THUNDERSTORMS WILL AFFECT
DAVIDSON...NORTHWESTERN MONTGOMERY...WESTERN RANDOLPH AND
NORTHEASTERN STANLY COUNTIES UNTIL 415 PM EDT...

At 307 PM EDT, Doppler radar was tracking an area of showers and
strong thunderstorms over Linwood, or near Lexington, moving east at
20 mph.

Wind gusts up to 50 mph will be possible with this storm.

Heavy rain and minor flooding and deadly cloud to ground lightning
will also be possible with this storm.

Locations impacted include...
High Point, Lexington, Troy, Badin Lake, Thomasville, Linwood,
Archdale, Trinity, Badin and Denton.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Seek shelter in a nearby building or vehicle. Wind gusts as high as
50 mph are capable of knocking down small or weakened trees and
blowing around trash cans, potted plants, lawn furniture and other
light outdoor objects.

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.

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