* WHERE...A portion of panhandle Nebraska, including the following 
  counties, Dawes and Sioux.

* WHEN...Until 730 PM MDT.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, dont drown when encountering flooded roads. Most flood 
deaths occur in vehicles.

Stay away or be swept away.

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.
