Degrees of Avalanche Danger ?
In windy alpine zones through the Pass, strong south winds likely stripped much of the new snow from south aspects, and heavily loaded north aspects. Recent wind slabs that have built up in the top meter of snowpack may still be sensitive to human weight. As temperatures drop this week and the snow continues to settle, the likelihood of triggering these slabs on north-ish aspects will continue to decrease.
But, as the north winds increase later this week, look for fresh wind slabs to be building on south aspects and east- and west-facing gullies. Any areas of fresh wind loading will create pockets of increased danger.
Recent Avalanche Activity
Over 11″ of precipitation fell in the last 10 days. Snow levels were between 1000 and 3500ft. Up to 12 feet of wet snow fell above treeline, and has settled to a 3-meter deep base at 4000ft, and around 1-meter deep at 2800ft. In other words, winter is here!
North winds this week will bring clearing, sunshine, and colder weather. No real storms in sight until next week.
