Variable wind direction has made the potential for wind slabs to be on any aspect.
Immediate lee features are of greatest concern.

With lots of soft snow on the surface, consider the hazard to be increasing if you see wind starting to move the snow into lee features.
Back down if you encounter signs of instability.

Avalanche Summary
On Monday explosive avalanche control produced large avalanches (up to size 2.5) and also noted sympathetic avalanches.
Natural, large (up to size 3) slab avalanches were reported over the weekend.
Snowpack Summary
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.
