818 PM EDT Tue Jun 8 2021

The National Weather Service in Charleston has issued a

* Flash Flood Warning for...
  Southeastern McDowell County in southern West Virginia...

* Until 1115 PM EDT.

* At 818 PM EDT, Doppler radar indicated thunderstorms had produced 
  heavy rain across the warned area for the second consecutive 
  evening. Between 1.5 and 2.5 inches of rain have fallen this 
  evening. Additional showers and thunderstorms could bring another 
  0.5 to 1 inch of rainfall in the warned area. Flash flooding is 
  ongoing or expected to begin shortly.

  HAZARD...Flash flooding caused by thunderstorms.

  SOURCE...Radar.

  IMPACT...Flash flooding of small creeks and streams, urban
           areas, highways, streets and underpasses as well as
           other poor drainage and low-lying areas.
