The main concern are wind slabs in the alpine and at treeline in immediate lee terrain features which were formed by wind with switching directions.
Wind has recently switched direction from northwest to southwest and back again. At treeline elevations, wind slabs may overly a crust which may make for a favorable sliding surface.
Wednesday Night: Cloudy with isolated flurries, light to moderate northwest wind, alpine high -6 C, freezing level 500 m.
Thursday: Cloudy with isolated flurries, light to moderate northwest wind, alpine high -5 C, freezing level 800 m.
Friday: Cloudy with sunny breaks, accumulation up to 10 cm, light northwest wind, alpine high -4 C, freezing level 900 m.
Saturday: Snow, accumulation 10-15 cm, light northerly wind, alpine high -5 C, freezing level 1100 m.
No new avalanche activity was reported in the last few days.
Wind switching directions has redistributed recent new snow onto a variety of aspects. As high as 2000 m, the upper snowpack contains a series of crusts from recent warming and rain events.
A layer of surface hoar is buried 100-150 cm below the surface in sheltered areas around treeline but has not been associated with avalanche activity recently. Weak facet/crust layers near the base of the snowpack are particularly noteworthy in the western Boundary area.
