Weather Forecast

Another 15-25 cm of snow is expected overnight Tuesday throughout Wednesday with moderate to strong southwesterly alpine winds and daytime high freezing levels reaching 1100 m. Thursday should be relatively dry with snow starting in the afternoon and continuing throughout Friday resulting in another 25-40 cm of accumulation with strong southwest alpine winds and freezing levels rising as high as 1500 m.

Avalanche Summary

No recent avalanche observations reported. If you have been out in the mountains, please submit your observations to the Mountain Information Network (MIN).

Snowpack Summary

Total snowpack depths are likely around 150 cm at treeline, and 2 m or more at higher elevations. The new snow continues to build weak storm slabs with particularly deep and touchy wind slabs on leeward slopes in exposed areas. However, warm temperatures are promoting rapid settlement and strengthening.

Avalanche Problems

Storm Slabs

Although settling and strengthening fast, forecast snow and winds are expected to keep slabs fresh and touchy.
Be alert to conditions that change with elevation.Be cautious as you transition into wind affected terrain.The new snow will require several days to settle and stabilize.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2
