Danger is on a decreasing trend after the recent storm. Best enjoy the good snow in sheltered areas away from the influence of the wind.
Wind slab avalanches exist on a variety of aspects in exposed terrain. Winds have been picking up quickly and there is plenty of fresh snow for transport, so wind slabs can build rapidly in new locations. The likelihood will diminish on Monday with anticipated calm winds.
Friday night: Around 5 cm new snow. Strong southwesterly winds.
Saturday: 2-5 cm new snow. Moderate southwesterly winds. Temperatures around -8C.
Sunday: Flurries. Light southeasterly winds. Temperatures around -11C.
Monday: Dry with some sunshine. Calm winds. Temperatures around -15C.
No recent avalanches have been reported on the Canadian side of White Pass despite the recent new snow and wind. On the American side, several avalanches of at least size 2 have been reported from highway elevations and in the alpine during the last few days.
20-30 cm new snow fell on Wednesday/Thursday with additional light amounts since then. This new snow has been redistributed by shifting winds, and wind slabs have been reported on a variety of aspects in exposed terrain. Cornices are reported to be growing in size.
At White Pass, where snowpack depths are between 180 and 250 cm, the mid and lower snowpack layers are well bonded. In the Wheaton Valley, the base of the thin snowpack comprises mainly of sugary facets and is capped by a breakable crust.
