Avalanche Summary

No new avalanches were reported before 4pm on Sunday.

Please help out your backcountry community by submitting a MIN report if you head out to the backcountry.

Snowpack Summary

Expected snowfall and rainfall will begin breaking down the upper snowpack at lower elevations and as south winds increase, will begin to build deeper wind slabs at higher elevations. Past storm snow is likely to have adhered effectively to the existing old surfaces. Below treeline, you'll find dirt, or shallow, heavy, moist or wet snow.

Previously mild temperatures and continuous rainfall have saturated and reduced the snowpack. The current snow depth ranges from 40 to 90 cm, diminishing rapidly below the 1000 m elevation threshold.

Terrain features with smooth ground cover, gullies, or established avalanche paths are above the threshold for avalanches.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Investigate the bond of the recent snow before committing to your line.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.

Avalanche Problems

Wind Slabs

New snowfall and strong souths winds will begin building new wind slabs in the alpine.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2

Loose Wet

As precipitation switches from snowfall to rainfall, expect the upper snowpack to become unconsolidated.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
