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
