    An increasingly well settled snowpack means triggering an avalanche on a deep persistent layer has become unlikely. However, large and destructive avalanches may be possible with a heavy load in steep, rocky start zones.

Confidence

Fair - Due to the number of field observations

Weather Forecast

A ridge of high pressure will continue to keep things cold and dry well into next week. We should see a mix of sun and cloud for all 3 days of the forecast period, and no significant precipitation is expected. Winds are expected be light and northerly. Alpine temperatures should hover around -15 for Sunday, dropping steadily to about -20 by Tuesday.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

In many areas light amounts of new snow overlie well developed surface hoar and old stubborn wind slabs. A melt-freeze crust is now buried on most slopes that saw direct sun last week. In some parts of the region the recent snow has been shifted by light winds into soft slabs, and in certain cases wind has stripped surfaces down to old hard slabs which formed weeks ago.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). No avalanche activity has been reported at this interface for some time; however, weaknesses continue to appear in snowpack tests. Although unlikely, avalanches at this interface could have nasty consequences. Possible triggers for this layer include cornice fall, rapid temperature change or a heavy load over a thin spot.
