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... 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 10000'. 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 10000') could see some minor inundation from snowmelt. Stay away from fast moving water and exercise caution near riverbanks and streams.
