Hydrologic Outlook issued May 31 at 11:59AM MDT by NWS Riverton WY

ESFRIW

Temperatures are expected to reach the mid to upper 80s this
weekend. Sunday will be the warmest day, with highs in the upper 80s
to low 90s across many locations. 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.
Highest stream flows and crests are expected to occur Sunday morning
and 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.
