Wind slabs at upper elevations are the main concern.
Watch out for reactive wind slabs in leeward terrain features such as ridgecrests and roll-overs.
On Monday there were reports of a few skier controlled wind slab avalanches to size 1. On Monday there were a few size 1-1.5 explosives controlled wind slab avalanches reported in the alpine and treeline.
Recent southwest winds have redistributed surface snow into leeward terrain features. In some areas, you may also find a thin, frozen crust near the surface.
The dry surface snow has bonded well to the crust left behind by last week's rain event. That crust is 40-60 cm deep and has been observed up to 5 cm thick in some places.
Beneath the upper crust, the remainder of the rain-moistened snowpack has slowly refrozen.
Snowpack depths vary across the forecast area. 50 to 120 cm at treeline, tapering rapidly below treeline.
