ESFPUB Risk of enhanced runoff and elevated stream flows from rapid snowmelt ...EXISTING CONDITIONS... Recent storms have brought several inches of snow water equivalent to mid to high elevations (8500'->10500') over the eastern San Juan and Sangre de Cristo Mountains of south-central Colorado, and along the Continental Divide of central Colorado. With upcoming precipitation, warming temperatures, and possible rain-on-snow for mid to high elevations, this region of Colorado is vulnerable to enhanced runoff and elevated stream flows from rapid snowmelt. ...PRECIPITATION... There is a roughly 25% chance of 0.1" or more of liquid precipitation over much of the area of concern today through Saturday afternoon. Precipitation in the form of rain could occur as high as 10,000 feet. This elevated chance of rain-on-snow, along with warmer temperatures, could accelerate melting of new and existing snowpack. ...STREAMFLOW CONDITIONS AND RUNOFF FORECASTS... Streams and rivers in the area could see elevated flows of dangerously cold water over the next several days. Low lying areas and valley floors could see some minor inundation from snowmelt. Stay away from fast moving water, exercise caution near riverbanks and stay alert to watches and warnings from the National Weather Service.

ESFGJT Risk of areal flooding and elevated stream flows from rapid snowmelt ...EXISTING CONDITIONS... Recent storms have brought several inches of new snow to mid to high elevations (8500' to 10,000') over the San Juans mountains, nosing along the Divide across Central Colorado. With forecast temperatures running 5 to 15 degrees above normal and the potential for showers and storms along the Divide each afternoon through the weekend, this region of western Colorado is vulnerable to enhanced runoff and elevated stream flows from rapid snowmelt. ...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') are most susceptible to swelling of area streams and/or localized inundation. Stay away from fast moving water and exercise caution near riverbanks and streams.

ESFGJT 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 increases from south to north. ...PRECIPITATION...
