Areas where the surface or near surface snow has been affected by the wind are most likely to be a concern.
Consider the hazard to be increasing if you see wind moving snow into lee features.
Variable wind direction has made the potential for wind slabs to be on any aspect.
Immediate lee features are of greatest concern.
30 to 70 cm of recent snow was accompanied by strong wind. In sheltered areas, the snow may rest on a weak layer of surface hoar.
The mid and lower snowpack are uncomplicated and relatively deep for the time of year. Snowpack depths in excess of 300 cm can be found at treeline elevations.
On Wednesday explosive avalanche control produced small (up to size 1.5) wind slab avalanches at treeline.
On Monday explosive avalanche control produced large avalanches (up to size 2.5) and also noted sympathetic avalanches.
