  West Central Pueblo County in southeastern Colorado...

* Until 515 PM MDT.

* At 216 PM MDT, Doppler radar indicated thunderstorms producing 
  heavy rain over the Junkins Burn Scar. Flash flooding is ongoing 
  or expected to begin shortly.

moving through the South Hardscrabble and North Creek. The debris 
flow can consist of rock, mud, vegetation and other loose materials.

  HAZARD...Life threatening flash flooding. Thunderstorms
           producing flash flooding in and around the Junkins
           Burn Scar.

  SOURCE...Doppler radar.

  IMPACT...Life threatening flash flooding of areas in and around
           the Junkins Burn Scar.

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

This includes the following high risk locations...
Hardscrabble Creek near County Road 389, Beulah Water Intake, Forest 
Road 387 Bridge at South Hardscrabble Creek, Northcreek Road county 
line to Red Mountain Camp and Northcreek Road from Red Mountain Camp 
to Beulah.

Additional rainfall amounts of 1 to 2 inches are possible in the 
warned area.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

This is a life threatening situation. Heavy rainfall will cause 
extensive and severe flash flooding of creeks...streams...and 
ditches in the Junkins Burn Scar. Severe debris flows can also be 
anticipated across roads. Roads and driveways may be washed away in 
places. If you encounter flood waters...climb to safety.

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.
