Points saillants

An isothermal snowpack exists at most elevations.

Exercise caution around steep slopes, where surface snow may remain unstable.

    Small loose wet avalanches are likely on steep slopes at all elevations, especially with strong sun. A surface crust, if present, may reduce the risk.

Moderate

Avalanche Summary

No new avalanche was reported, but field observations are limited. Old debris from natural wet avalanches may still be visible throughout the region.

Snowpack Summary

Up to 40 cm of moist to wet snow sits on the decomposing buried crust. The late-January weak hard crust is buried 100 to 150 cm deep. Below this, the snowpack is strong and bonded.

At lower elevations, rain has soaked the snowpack, and the coverage is thin.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation and sun exposure.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Make observations and continually assess conditions as you travel.
