Snowfall amounts are highly variable throughout the region.
If you find more than 20 cm of new snow, treat the danger as CONSIDERABLE
New snow arrives with moderate to strong southwest wind. Surface hoar and facets exists beneath the new snow at higher and in sheltered locations.
Weak layers exist 40 to 100 cm deep. These layers remain a concern where there is no thick, supportive crust under the recent snow.
A few small to large wind slab avalanches have been reported on North through East terrain at treeline and above. These have been triggered by cornice fall and riders.
Looking forward: Avalanches on buried weak layers may be difficult to trigger, but if one is triggered, it is likely to be large and destructive.
Up to 18 cm of new snow has been redistributed by southwest wind. This snow sits on a crust on solar aspects and all aspects below 1800 m. Above this, surface hoar or facets exist in sheltered areas and on north aspects.
Two concerning weak layers are present in the mid snowpack: facets/surface hoar or a crust from mid-February buried 30-70 cm, and facet/surface hoar/crust from late January buried 60-100 cm.
