Avalanche Summary
A handful of small (size 1) skier-triggered storm and wind slab avalanches up to 30 cm deep were reported in the alpine on Monday. Solar-triggered loose wet avalanches were observed up to size 2 in steep alpine terrain.
Last week, cornice failures were notably not propagating any weak layers on slopes below but there was one report of an anomalous remotely skier-triggered size 2 failing on moist snow below a recently buried crust.
Snowpack Summary
A dusting of new snow falls over widespread crusty surfaces on all but high north-facing alpine terrain, where snow is dry and likely wind affected. There are no deeper concerns at this time.

Terrain and Travel Advice
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
Problems
Wind Slabs
Small wind slabs may remain triggerable in lee terrain features at upper elevations. They may be especially reactive where they sit over a crust.
