...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 1030 PM EDT FOR
SOUTHEASTERN FULTON COUNTY...

At 827 PM EDT, local law enforcement reported flash flooding in 
McConnellsburg. Up to three inches of rain have already fallen over 
eastern Fulton County. 

The rain is moving to the south and is to the south of 
McConnellsburg and should continue moving to the south. The rain may 
end before 9 PM EDT in Warfordsburg. However, additional rain may 
generate flooding in new locations. Generally less than another inch 
is expected to fall across far southern Fulton County through 10 PM 
EDT.

Some locations that will experience flooding include...
Big Cove Tannery, McConnellsburg, Needmore, Warfordsburg and 
Harrisonville. The most likely streams to experience flooding

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, country roads, farmland, and other low lying
spots.

Please report flooding to your local law enforcement agency when you
can do so safely.
