Strong southerly winds overnight on Monday - Tuesday will rapidly build wind slabs.
Make conservative choices if the forecasted winds materialize.
Incremental loading over the weekend followed by 10cm on Tuesday has made plenty of snow available for transport. Moderate to Strong wind Monday night and Tues will rapidly increase the wind slab hazard. This avalanche problem will be most reactive in the alpine and exposed areas at tree line.
Limited visibility on Monday
Several natural avalanches up to size 2 were observed in the highway corridor on Sunday from steep, north-facing slopes in the alpine. These avalanches occurred due to a previous wind spike.
A natural avalanche cycle is expected on Tuesday.
We've received ~80cm of new snow since Dec 18th. This recent snow has fallen with moderate Southerly winds which are forecast to rise rapidly overnight- Tuesday. Expect wind slabs to build quickly! A persistent weak layer is down 80-110cm. This interface is breaking down, but consists of surface hoar in sheltered locations, and a sun crust on solar aspects. The snowpack's base is comprised of several early-season melt-freeze rain crusts
A series of low pressure systems will bring some precipitation and strong wind.
