Avalanche Summary

No new avalanches were reported before 4pm on Friday.

If you do head into the backcountry please consider submitting observations and/or photos on the Mountain Information Network.

Snowpack Summary

Yesterday we saw moderate snowfall and rainfall accompanied by strong southwest winds and decreasing temperatures. Anticipate the wind stripping south and west-facing ridges down to frozen crusts, while deeper and more reactive slabs form on north and east-facing slopes.

Below treeline, you'll likely find dirt, or shallow, heavy, moist or wet snow.

The mid and lower snowpack is made up of a series of crusts and rounded grains. The snowpack is generally well consolidated.

Overall, the snow depth remains shallow, creating challenging travel conditions and hiding early season hazards just below the snow surface.

Weather Summary

Friday Night

Partly cloudy. A trace of snow expected. Treeline temperature around -4 °C. Freezing level around 800 m. Light southwest ridgetop wind

Saturday

Partly cloudy. A trace of snow expected. Treeline temperature around -6 °C. Freezing level around 500 m. Light southwest ridgetop wind

Sunday

Partly cloudy. No new snow expected. Treeline temperature around 0 °C. Freezing level rising to 1200-1500 m, possible temperature inversion. Strong south ridgetop wind.

Monday

Cloudy. Heavy snow and rain expected. Freezing level rising to 1200-1500 m. Treeline temperature around 0 °C. Extreme south or southwest ridgetop wind.

Terrain and Travel Advice

  • Be careful to keep storm day fever from luring you out into bigger terrain features.
  • Be cautious of buried obstacles especially below treeline.

Avalanche Problems

Storm Slabs

Rider triggerable storm slabs may be forming around treeline elevations and above, where new snow is falling on terrain that was already at threshold for avalanches. The touchiest slabs may be in lee terrain features.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
