BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Pueblo CO
517 PM MDT WED JUL 25 2018

The National Weather Service in Pueblo has issued a

* Flash Flood Warning for...
  East central Teller County in central Colorado...
  West central El Paso County in east central Colorado...

* Until 815 PM MDT.

* At 515 PM MDT, local law enforcement reported thunderstorms
  producing heavy rain across the warned area. Flash flooding is 
  expected to begin shortly along Fountain Creek, especially near 
  Woodland Park where the heaviest rain has fallen.  Locations near 
  the Waldo Canyon burn scar may also experience debris flows due to 
  the heavy rainfall.

* Some locations that will experience flooding include...
  Western Colorado Springs, Woodland Park, Manitou Springs, Green
  Mountain Falls, Crystola, Chipita Park, Cascade, Stratmoor and Fort
  Carson.

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

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

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.
