Stanly NC-
206 PM EDT SUN JUL 23 2017

...A STRONG THUNDERSTORM WILL AFFECT SOUTHERN STANLY COUNTY UNTIL 245
PM EDT...

At 204 PM EDT, Doppler radar was tracking a strong thunderstorm 7
miles south of Plyler, or 9 miles southwest of Albemarle, moving
southeast at 10 mph.

Deadly cloud to ground lightning and wind gusts up to 50 mph will be
possible with this storm.

Locations impacted include...
Albemarle, Norwood, Oakboro and Lake Tillery.

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.

Boaters on the open water and those camping outdoors are especially
vulnerable to the dangers of lightning. Seek harbor immediately and
find safe shelter in a nearby building or vehicle. Remember, if you
can hear thunder, you are close enough to be struck by lightning.
