Northwest Pocahontas WV-
513 PM EDT Thu Aug 26 2021
...Downpours will impact portions of northeastern Pocahontas County
through 615 PM EDT...
At 508 PM EDT, Doppler radar was tracking thunderstorms with heavy
rainfall 8 miles northeast of Greenbank, moving north at 10 mph.
HAZARD...Heavy rain.
SOURCE...Radar indicated.
IMPACT...Heavy rainfall will cause rapid rises on small streams and
creeks. Campers and backpackers should stay away from creek
banks as runoff continues.
This storm will remain over mainly rural areas of northeastern
Pocahontas County.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
If outdoors, consider seeking shelter inside a building.
Excessive runoff from heavy rainfall will cause elevated levels on
small creeks and streams, and ponding of water on country roads and
farmland along the banks of creeks and streams.
In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to travel across
flooded roads. Find alternate routes. It takes only a few inches of
swiftly flowing water to carry vehicles away.
