Hydrologic Outlook

National Weather Service Riverton WY

106 PM MDT Sun Jun 1 2025



...Warm Temperatures continue to increase high-elevation snowmelt 

and flooding potential...



Temperatures are expected to reach the upper 80s to low 90s across 

many locations Sunday. Low temperatures will also remain well above 

freezing with low temperatures in the 40s at elevations above 9500 

feet. These warm temperatures will continue to lead to an increase 

in the rate of mountain snowmelt.



Most mountain snowpack below 9500 feet has melted out, however, 

high-elevation mountain snow water equivalent (SWE) above that level 

still remains. With the expected warm temperatures, a significant 

portion of that high-elevation snowpack is expected to continue to 

melt through Sunday night. Minor flooding of small streams and 

creeks fed by mountain snowmelt is thus possible through Monday 

morning. Highest stream flows and crests are expected to occur 

Monday morning.



Stay tuned for the latest river forecasts. Remember, if you 

encounter a flooded roadway, turn around don't drown. You never know 

what road conditions are hidden under the water.
