    Snow is expected to switch to rain in the afternoon as freezing levels rise to 2100 m. Wet loose avalanches could become easy to trigger as the snow surface becomes moist or wet for the first time.

Avalanche Summary

No avalanches have been reported. However, observations are limited in this region.

If you're heading out into the backcountry, please consider sharing your observations on the MIN.

Snowpack Summary

New snow is forming fresh wind slabs on leeward features and scouring windward slopes at upper elevations. Recent snowfall has buried several layers, including surface hoar, facets, and a sun crust. These older layers now lie 20 to 35 cm below the surface.

Areas below 2100 m may see rain on Monday afternoon, turning the snow surface moist or wet at lower elevations. Snowpack height averages around 100 cm at treeline and decreases rapidly below about 1500 m.

A firm crust that formed in early November can be found buried 40 to 90 cm at alpine and treeline elevations. Weak facets have been spotted above and below the crust.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
