Avalanche Summary

We have had very little information about recent avalanche activity from this region. Based on observations from the Northwest Coastal region, I would expect wet loose snow avalanches have been occurring up to size 2 on solar aspects.

Snowpack Summary

We have had very little information about the snowpack in this region for several days now. However, I suspect the warmer temperatures and generally light winds have consolidated the snowpack in many areas. Anticipate extensive crusts on solar aspects and moist snow at lower elevations. On shady aspects, I suspect you can still find pockets of dry snow, which may sit over previous old wind slabs. Wet slabs become a possibility during periods of prolonged warming, especially if there is minimal amounts of overnight freeze. Expect cornices to be large and potentially unstable, especially under sunny skies

Avalanche Problems

Cornices

Large cornices exist in alpine terrain and may pop off with warmer temperatures.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 5

Wind Slabs

Fresh deposits of new snow may become redistributed by wind into small pockets on lee slopes.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 2
