    As the temperature drops triggering an avalanche on deep persistent layers will become less likely.  However, large and destructive avalanche may be possible in steep, rocky start zones with thin or variable snow cover.

Good

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

Between 5 and 20cm of new snow overlies a variety of surfaces including: old wind slabs in exposed terrain, well developed surface hoar in sheltered areas, or a melt-freeze crust on sun-exposed slopes.The main concern in the region continues to be the weak buried faceted snow which exists in the mid or lower snowpack (depending where you are in the region). Although avalanche activity on this interface has tapered-off lately there is still the potential for large avalanche that could have nasty consequences. Possible triggers for this layer include cornice fall, or a heavy load over a thin spot.
