...A STRONG THUNDERSTORM WILL AFFECT SOUTHERN SAMPSON COUNTY UNTIL
615 PM EDT...

At 521 PM EDT, Doppler radar was tracking an area of strong
thunderstorms centered about 10 miles southeast of Ammon, or 13
miles northeast of Elizabethtown, moving northeast at 30 mph.

Wind gusts up to 50 mph and very heavy rainfall will be possible
with this storm. Visibility will likely be reduced by the heavy
rainfall rates, and pockets of small stream flooding will be likely.
Use caution, especially if traveling.

Locations impacted include...
Clinton, Harrells, Roseboro, Garland, Turkey and Ivanhoe.

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.
