...Warm Temperatures through Thursday May Lead to Flood Impacts from 

Efficient Low and Mid Elevation Snowmelt...



Temperatures will continue to run well above average through 

Thursday, increasing low and mid elevation snowmelt and runoff. 

Standing water in typical low spots can be expected, and we'll also 

likely begin seeing the swelling of smaller creeks and tributaries 

that feed the larger streams and rivers. This may even push some 

streams and creeks above bankfull causing minor flooding and bank 

erosion due to the higher flows.



Temperatures will remain anomalously warm until a cold front passage 

Thursday. Even the overnight lows will stay above freezing through 

Thursday night, which will exacerbate snowmelt runoff.



A cooldown is forecast to arrive Thursday night with temperatures 

Friday and Saturday dipping back down toward normals, and overnight 

lows back to near freezing by Saturday morning. This cooldown, 

however, will be accompanied by increasing rain chances which could 

add to the runoff concerns.



Stay away from fast moving water, swollen river banks, and never 

attempt to cross flowing water over roadways.
