...Warm Temperatures this Weekend will increase high-elevation
snowmelt and flooding potential...

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 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 melt Saturday through
Sunday night. Minor flooding of small streams and creeks fed by
mountain snowmelt is thus possible Saturday through Monday.

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.
