Avalanche Summary

No new avalanches have been reported in the past 3 days at the time of publishing. We suspect that human triggered avalanches could have occurred during the day on Wednesday.

Snowpack Summary

Up to 30 cm of recent snow sits on a widespread surface crust. Below, the upper snowpack is moist.

The snow surface will likely become moist during the day on all aspects and elevations except for high north facing slopes.

Several decomposing crusts may be found in the mid snowpack.  The remainder of the snowpack is dense and well-bonded.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Be alert to conditions that change with elevation and sun exposure.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
