 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.
