Continue to practice safe travel habits in the backcountry.

Watch for blowing snow forming wind slabs, and scale back your objective if you find signs of instability like shooting cracks.

Avalanche Summary

No new avalanches have been reported but information is limited.

Please consider submitting your observations to the MIN if you head to the backcountry.

Snowpack Summary

10 to 25 cm of recent snow sits on a hard melt-freeze crust except for shady high alpine slopes, where it sits on faceted snow over a hard crust. Thicker deposits may exist in lee terrain features near mountain tops.

Below 1500 m, expect the snow surface to be moist due to light rain.

A layer of weak faceted grains above a hard crust that formed in early February is buried about 50 to 110 cm deep. This layer is currently dormant.

Weather Summary

Monday Night

Cloudy. Light rain expected, 5-10 cm of snow above 1500 m. Strong southwest ridgetop wind. Treeline temperature around 1 °C.

Tuesday

Cloudy. Light rain expected, 5 cm of snow above 1500 m. Likely heavier precipitation between Kakwa and Tumbler Ridge. Strong southwest ridgetop wind. Treeline temperature around 0 °C.

Wednesday

Partly cloudy. Light precipitation continues as freezing level drops to valley bottom. Up to 15 cm of snow expected in the south end of the forecast area. Light to moderate west or southwest ridgetop wind. Treeline temperature around -5 °C.

Thursday

Partly cloudy. No new snow expected. Light variable ridgetop wind. Treeline high around -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Wind slabs are most reactive during their formation.
  • Make observations and assess conditions continually as you travel.

Avalanche Problems

Wind Slabs

Pockets of wind slab may exist in terrain features immediately adjacent to ridges.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2
