Avalanche Summary
No new avalanches were reported in this region on Saturday. However, field observations are currently very limited in this region.
Please consider sharing your observations to the Mountain Information Network.
Snowpack Summary
In localized areas that receive more than 15 cm of new snow, fresh wind slabs may form on lee features in the alpine.
A hard melt-freeze crust exists on the snow surface on sun-exposed slopes to the mountain tops. The crust will transition to wet snow with daytime warming and generally re-freeze at night.
Dry snow and small isolated wind slabs may still exist on shady slopes in the high alpine.
Cornices are large and may become weak with daytime warming.
