If you venture into the high country in search of soft snow, exercise caution in wind-loaded areas. Reactive wind slabs may exits in lee terrain features.

Avalanche Summary

Challenging travel at low elevations has limited access to the mountains in many areas and no new avalanches have been reported.

If you are getting out in the backcountry, let us know what you are seeing by making a post on the MIN (Mountain Information Network). 🙏

Snowpack Summary

At upper elevations, last week's snowfall was redeposited by strong southwest shifting to east winds. A hard crust exists on the surface on all aspects to at least 1600 m.

A layer of weak faceted snow above a hard crust formed in early February and is now buried 50 to 120 cm deep. This layer is generally getting stronger and is shielded by crusts above it. It has not produced any recent avalanches.

Weather Summary

Saturday Night

Cloudy with mixed precipitation, up to 5 cm new snow accumulation at higher elevations. Ridge wind 40 to 60 km/h from the southwest. Treeline temperature drops to -7 °C. Freezing level drops to valley bottom.

Sunday

A mix of sun and cloud with light flurries. Ridge wins 40 to 60 km/h from the southwest. Treeline temperatures reach a high of -4 °C. Freezing level rises to 1500 m.

Monday

Cloudy with mixed precipitation, 5 to 10 cm new snow accumulation at higher elevations. Ridge wind 50 to 80 km/h from the southwest. Treeline temperature -3 °C, freezing level 1600 m.

Tuesday

Cloudy with mixed precipitation, up to 5 cm of new snow accumulation at higher elevations. Ridge wind west 40 to 60 km/h. Treeline temperature -3 °C, freezing level 1500 m.

Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Approach lee and cross-loaded slopes with caution.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.

Avalanche Problems

Wind Slabs

New snow and southwest winds may form fresh wind slabs in the alpine and treeline. Older stiff wind slabs may exist on south slopes from previous strong northerly winds.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
