...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 645 PM MDT FOR
SOUTHERN MESA AND WEST CENTRAL MONTROSE COUNTIES...

At 501 PM MDT, Doppler radar indicated showers and thunderstorms
producing additional heavy rain across the warned area. Radar
indicates half an inch to an inch of rain has fallen so far. Flash
flooding is expected to begin shortly.

Excessive rainfall over the burn scar will result in debris flow
moving through many of the fire affected drainages. The debris flow
can consist of rock, mud, vegetation and other loose materials.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

...Flash Flood Watch in effect for Badger Creek Burn Scar and the
southern Snowy Range in southwest Laramie County...

.Flash flooding and debris flows near the Badger Creek burn scar
in southwest Laramie County could occur this afternoon and
evening as heavy showers and thunderstorms will be near the
vulnerable area. The flash flooding and debris flows could occur
rapidly if a high rainfall rates were to move over the burn scar
and the probability of this is at least 50-70% per latest
analysis. A quick half inch of rainfall could cause flows to occur
but upwards of one inch or greater in the worst case scenario
could also be possible. Please stay highly alert in and near the
burn scar from noon through midnight today. The flash flood and
debris flow risk will reduce after midnight when the stronger
showers and storms shift farther east into the High Plains.
