Risk of areal flooding and elevated stream flows from rapid snowmelt

…OVERVIEW…
Mid to high elevations (8500′ to 10000/) along the San Juan
Mountains and along the Divide through central Colorado are
susceptible to enhanced runoff and elevated stream flows from rapid
snowmelt.

…TEMPERATURE…
High temperatures will continue to run 5 to 10 degrees above normal
through the weekend, with overnight lows remaining above freezing
for mid to high elevations. This warming trend carries into Monday,
resulting in highs climbing 10 to 15 degrees above normal. Said
departure from normal temperatures increases from south to north.

…PRECIPITATION…
Isolated to scattered showers and storms developing each afternoon
favor high terrain across the southwest San Juans and along the
spine of the Divide. Due to warming conditions, precipitation in the
form of rain is possible as high as 10,000′. Although anticipated
storm totals are low, generally 0.1″ to 0.2″, rain-on-snow could
enhance the rate of snowmelt.

…STREAMFLOW CONDITIONS AND RUNOFF FORECASTS…
Streams and rivers in the area will see elevated flows of
dangerously cold water over the next several days. Low-lying areas
across mountainous terrain (8500′ to 10,000′) could see some minor
inundation from snowmelt.

Stay away from fast moving water and exercise caution near
riverbanks and streams.
