Storm snow and wind have built fresh slabs at higher elevations. Use caution in wind-affected terrain where deeper deposits exist and human-triggered avalanches are possible.
+20 cm of new snow and wind have built fresh slabs at higher elevations. The deepest deposits can be found in north and east facing lee terrain features. Evaluate wind-affected areas carefully, human-triggered avalanches are possible.
On Tuesday, explosives control in the region produced storm slab results up to size 2.5. Several size 2 natural avalanches were observed in steep northerly terrain.
On Monday, a few loose wet avalanches were reported in steep alpine terrain, size 1-2.
10 to 30 cm of storm snow covers the surface at higher elevations. The new snow sits above a crust or moist snow except on high northerly aspects above 2200 m where snow remained dry.100 to 50 cm down is a layer of weak faceted grains above a crust, formed in early February. This layer has generally been gaining strength, however it is still occasionally producing large avalanches at upper elevations where supportive crusts have not formed above it.
