Highlights

Elevated avalanche danger may exist in areas that have received 10 cm or more of recent snow atop a crust, particularly during periods of intense solar radiation and daytime warming.

    The likelihood of both slab and loose avalanches will increase with daytime warming and sun exposure, particularly in areas that recently received new snow.

Avalanche Summary

No recent avalanche activity has been reported. However, field observations are currently very limited.

Snowpack Summary

Anywhere from 0 to 10 cm of new snow sits atop a widespread melt-freeze crust, existing across all aspects and elevations except for north-facing alpine terrain.

A series of variable melt-freeze crusts exist in the upper snowpack.

The lower snowpack is generally well-bonded and strong.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Closely monitor how the new snow is bonding to the crust.
  • Be alert to conditions that change with elevation and sun exposure.
