Flash Flood Warning
National Weather Service Pueblo CO
342 PM MDT WED JUN 7 2017

The National Weather Service in Pueblo has issued a

* Flash Flood Warning for...
  Northeastern Custer County in southeastern Colorado...
  West central Pueblo County in southeastern Colorado...

* Until 645 PM MDT

* At 340 PM MDT, Doppler radar indicated thunderstorms producing
  heavy rain across the warned area. Flash flooding is expected to
  begin shortly.

* Some locations that will experience flooding include...
  Junkins Burn Scar, Beulah and Wetmore. 

Excessive rainfall over the burn scar will result in debris flow 
moving through the South Hardscrabble, Hardscrabble and North Creek. 
The debris flow can consist of rock, mud, vegetation and other loose 
materials.

Additional rainfall amounts of up to an inch are possible in the 
warned area.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Move to higher ground now. Act quickly to protect your life.
