Forecast new snow may release as loose wet avalanches during the warmest part of the day. Some thin wind slabs may also develop in the alpine.

Avalanche Summary
There have been no recent reports of avalanche activity in the south of the region. That being said there is little to no information being passed on from the region recently. Exposure to large overhanging cornices remains a significant concern. Forecast new snow may release as loose wet avalanches from steep terrain during exposure to the sun or from daytime warming.
Snowpack Summary
Recent snow has been transported by the wind, and high alpine terrain may be stripped down to ice or old hard surfaces. Wind deposited snow may be sitting on a variety of old surfaces including hard wind crusts in exposed terrain and sun crusts on solar aspects. At the tree line elevation, warming and refreezing earlier in the week has created melt freeze crusts. Below tree line the surface snow is likely a mix of crusts at the upper end of the elevation band to moist or wet snow throughout the entire thickness of the snowpack at the lower portions of the elevation band.
