Variable winds have created reactive wind slabs on all aspects and could be at elevations lower than expected.
Seek out the best snow in areas sheltered by the wind.
Shifting winds have begun to redistribute recent storm snow on nearly all aspects. Reactive to touchy wind slabs are to be expected.
Although this problem is most likely to be seen at higher elevations, you should expect to see wind slabs in exposed areas even below treeline elevations.
Operators in our area have reported natural and human triggered wind slab avalanches up to size 2. These have occurred in the alpine and treeline and on a variety of aspects and released at depths of around 40 cm.
Variable winds have begun to redistribute this past week's storm snow. Wind slabs are expected in exposed terrain on all aspects at lower than expected elevations. In some areas, this new snow has bonded poorly to the underlying surface consisting of stiff wind slabs and facets formed by last week's wind and cold temperatures.
Deeper in the snowpack 60 to 180 cm down exists two crusts with facets sitting above them. They can be found in alpine and treeline elevation bands. If triggered these layers could produce massive avalanches.
The remainder of the mid and lower snowpack is well-settled, strong, and consolidated.
