New snow and wind loading may have formed reactive wind slabs, particularly on north through east–facing slopes.
It's a good day to stick to conservative terrain sheltered from the wind.
Recent snow combined with strong winds on Wednesday may form fresh wind slabs on north through east aspects, especially at higher elevations.
No new avalanches reported on Monday.
Numerous natural storm slab avalanches (size 1.5) were reported on Sunday. Reports of widespread cracks and whumpfs in the upper snowpack were seen in flats with audible avalanche activity throughout the storm.
Reactive wind slabs may be found in the alpine and treeline on Wednesday.
Over the past four days, over 100 cm of new snow has fallen on a widespread layer of surface hoar ranging from 30 mm below treeline to 5 mm in the alpine.
A crust from early February is down 90 to 150 cm and in most areas appears to be well bonded. However, snowpack tests showed concerning results on this layer in the Prince of Wales range last Wednesday.
The remainder of the snowpack is well settled. The snowpack depth at treeline ranges from 95 to 200 cm, and there is still very little snow below treeline.
