BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Pueblo CO
326 PM MDT TUE JUN 6 2017

The National Weather Service in Pueblo has issued a

* Flash Flood Warning for...
  Northwestern El Paso County in east central Colorado...

* Until 630 PM MDT

* At 325 PM MDT, Doppler radar indicated thunderstorms producing 
  heavy rain over eastern portions of the Waldo Canyon burn scar, 
  along with the city of Colorado Springs. Flash flooding is 
  expected to begin shortly.

* Some locations that will experience flooding include...
  Colorado Springs, Monument, Air Force Academy, Manitou Springs,
  Black Forest, Gleneagle, Peterson AFB and Cimarron Hills.

Excessive rainfall over the burn scar will result in debris flow 
moving through the Waldo Canyon Burn Scar. 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.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, urban areas, highways, streets and underpasses as
well as other drainage areas and low lying spots.

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.

...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 630 PM MDT FOR
NORTHWESTERN EL PASO COUNTY...

At 351 PM MDT, Doppler radar indicated thunderstorms producing heavy 
rain across much of Colorado Springs.  Flash flooding is currently 
ongoing.  Public has reported multiple roads with flowing water 
along with slow moving traffic due to the water on roadways.

Excessive rainfall over the Waldo Canyon burn scar could result in 
debris flow moving through the east side of the burn scar. The 
debris flow can consist of rock, mud, vegetation and other loose 
materials.

Some locations that will experience flooding include...
Colorado Springs, Monument, Air Force Academy, Manitou Springs, Black
Forest, Gleneagle, Peterson AFB and Cimarron Hills.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, urban areas, highways, streets and underpasses as
well as other drainage areas and low lying spots.

Remain alert for flooding even in locations not receiving rain.
Arroyos, streams, and rivers can become raging killer currents in a
matter of minutes, even from distant rainfall.

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.
