Flash Flood Warning
National Weather Service Pueblo CO
241 PM MDT SUN JUL 16 2017
The National Weather Service in Pueblo has issued a
* Flash Flood Warning for...
Southwestern Fremont County in central Colorado...
Northwestern Custer County in southeastern Colorado...
* Until 445 PM MDT
* At 238 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...
The Hayden Pass Burn Scar, Hayden Creek Campground, Coaldale.
Excessive rainfall over the burn scar will result in debris flow
moving directly across the Hayden Pass 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, country roads, farmland, and other 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.
Flooding is occurring or is imminent. It is important to know where
you are relative to streams, rivers, or creeks which can become
killers in heavy rains. Campers and hikers should avoid streams or
creeks.

...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 445 PM MDT FOR
SOUTHWESTERN FREMONT AND NORTHWESTERN CUSTER COUNTIES...
...THIS INCLUDES THE HAYDEN PASS BURN SCAR...
At 304 PM MDT, Doppler radar indicated thunderstorms producing
heavy rain across the warned area. Doppler radar estimates up to 1
inch of rain has already fallen across the headwaters of Hayden
Creek and Wolf Creek, over the northwest portion of the scar. Flash
flooding is expected to begin shortly.
Excessive rainfall over the burn scar will result in debris flow
moving through the Hayden Creek, Wolf Creek, Big Cottonwood Creek,
Little Cottonwood Creek and Butter Creek Drainages. The debris flow
can consist of rock, mud, vegetation and other loose materials.
Some locations that will experience flooding include...
Hayden Creek Campground, County Road 6, County Road 40 and
possibly Coaldale.
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, country roads, farmland, and other 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.
Flooding is occurring or is imminent. It is important to know where
