BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Charleston WV
1005 PM EST Sun Feb 28 2021

The National Weather Service in Charleston has issued a

* Flash Flood Warning for...
  Lawrence County in northeastern Kentucky...
  Wayne County in western West Virginia...

* Until 100 AM EST.

* At 1005 PM EST, Doppler radar and automated rain gauges indicated 
  heavy rain falling across the warned area. Between 3 and 4 inches 
  of rain have fallen. Additional rainfall amounts of 0.5 to 1.5 
  inches are possible in the warned area in moderate to heavy 
  rainfall rates. Rainfall runoff is becoming critical in the warned 
  area where some flooding has already been occurring. Flash 
  flooding is ongoing or expected to begin shortly.

  HAZARD...Flash flooding caused by heavy rain.

  SOURCE...Radar and automated gauges.

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

* Some locations that will experience flash flooding include...
  Louisa, Wayne, Blaine, Yatesville Lake State Park, Fort Gay, 
  Dunlow, Ulysses, Charley, East Lynn Lake, Kiahsville, Martha, 
  Gallup, Glenhayes, Clifford, Genoa, Fallsburg, Crum, East Lynn, 
  Wilsondale and Houckville.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

In hilly terrain there are hundreds of low water crossings which are 
potentially dangerous in heavy rain. Do not attempt to cross flooded 
roads. Find an alternate route.
