Avalanche Forecast

Low - Uncertainty is due to limitations in the field data.

Saturday night: Cloudy, 5-10 cm of new snow, moderate southwest wind gusting strong at ridge-tops, freezing level dropping to 1300 m, alpine temperatures reach -5 C.

Sunday: Cloudy, up to 5 cm of new snow, moderate southwest wind gusting strong at ridge-tops, freezing level climbing to 1400 m in the afternoon, alpine temperatures reach -6 C.

Monday: Cloudy, 5-15 cm of new snow, moderate southwest wind, freezing level climbing to 1200 m in the afternoon, alpine temperatures reach -6 C.

Tuesday: Cloudy, scattered flurries with a trace of new snow, light southwest wind, freezing level climbing to 1000 m in the afternoon, alpine temperatures reach -7 C.

Slab avalanches are a concern on slopes with accumulations of new snow, especially in wind-loaded terrain. Mountain travel and field observations over the past week have been very limited. Little is known about recent avalanche activity.

New snow and strong southwest winds are building reactive storm slabs and creating dangerous avalanche conditions. 

Snowfall from earlier in the week was highly variable across the region with some areas receiving 15-25 cm and adjacent valleys getting as little as 0-5 cm. Some of the heavier accumulations fell in the south part of the region. This snow covered a variety of previous snow surfaces including crusts, warm snow, and wind-affected snow. It may also sit above some small surface hoar on shaded, sheltered slopes. Overall, there is some uncertainty about how well the snow has bonded to these interfaces.

Northern parts of the region have had a deep instability lingering at the base of the snowpack for most of the season, however this layer has gained strength over the past month (with the last reported avalanche on Feb 17).

• Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
