BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Pueblo CO
746 PM MDT Fri Jul 23 2021

The National Weather Service in Pueblo has issued a

* Flash Flood Warning for...
  Western Fremont County in central Colorado...
  Northeastern Saguache County in central Colorado...

* Until 1045 PM MDT.

* At 746 PM MDT, Doppler radar indicated thunderstorms producing 
  heavy rain across the warned area. Between 0.5 and 1 inch of rain 
  has fallen. The expected rainfall rate is 2 to 3 inches in 1 hour. 
  Flash flooding is ongoing or expected to begin shortly. There is 
  already a Flash Flood Warning for the northern portion of the 
  Decker Burn Scar, this extends the Flash Flood Warning further 
  south.

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

  HAZARD...Life threatening flash flooding. Thunderstorms
           producing flash flooding.

  SOURCE...Radar.

  IMPACT...Life threatening flash flooding of creeks and streams,
           urban areas, highways, streets and underpasses.

* Some locations that will experience flash flooding include...
  Southern Decker Burn Scar.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Move away from recently burned areas. Life-threatening flooding of 
creeks, roads and normally dry arroyos is likely. The heavy rains 
will likely trigger rockslides, mudslides and debris flows in steep 
terrain, especially in and around these areas.

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