Isolated wind slabs may still be reactive in the alpine. Use caution as you transition into wind-affected terrain.
Isolated wind slabs may be lingering in the alpine. Up to 10 cm of snow will be blown into lee features by strong west to northwest winds.
Several natural and human-triggered wet loose avalanches were reported on Saturday. This problem is expected to diminish as freezing levels drop and cooler temperatures return.
True north aspects in the alpine remain the only areas holding dry snow with moist conditions at treeline and wet snow below. The moist snow will likely form a supportive crust by Tuesday morning at all elevations on solar aspects and between 2000 and 2500 m on polar aspects.
Below the surface crust, the snowpack consists of 10 to 20 cm of moist snow over a series of melt-freeze crusts. The melt-freeze crust from mid-March is widespread, found 10 to 80 cm below the surface depending on elevation and location.
The lower snowpack is strong and well-bonded.
