The National Weather Service in Raleigh has issued a
* Flash Flood Warning for...
Davidson County in central North Carolina...
Randolph County in central North Carolina...
Southern Guilford County in central North Carolina...
* Until 245 AM EDT
* At 1155 PM EDT, Doppler radar indicated thunderstorms producing
heavy rain across the warned area. Up to two inches of rain have
already fallen from central Davidson County to northwestern
Randolph County. Additional thunderstorms to the west southwest,
from near Kannapolis and Lincolnton, will track northeastward and
repeat over the warned area. As such, flash flooding is expected
to begin shortly.
* Some locations that will experience flooding include...
High Point, Asheboro, Lexington, Randleman, North Carolina Zoo,
Thomasville, Linwood, Archdale, Trinity and Pleasant Garden.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Excessive runoff from the heavy rain will cause flash flooding of
creeks and streams, roads, low lying and poor drainage areas. Do not
drive your vehicle into areas where water covers the road. Many roads
and intersections in the area will quickly flood. When encountering
flooded roads, turn around, don't drown.
