Weather Forecast

We're looking at a period of fairly benign weather leading into the weekend. There may be some isolated flurries although no significant accumulations of new snow are expected. An artic front just inland stretches almost all the way down the coast and will keep freezing levels at, or close to valley floor throughout the forecast period. Winds will be light and variable Tuesday and Wednesday before becoming moderate westerlies by Friday.

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

A skiff of new snow may be covering thin stiff wind slabs in alpine and above tree-line features on a variety of aspects lee to the variable recent winds. These winds have been mainly out of the northeast in areas under the influence of cold arctic air, and out of the south or southeast when the snowstorms have moved inland from the coast. Below this we're still dealing with a thin, early-season snow pack for much of the Northwest Inland region. Between 80 and 100 cm of snow can be found at tree-line in the south and west of the region, with closer to 60 cm in the east. A layer of surface hoar has been reported to be just below the surface in isolated sheltered areas although it may be hard to find. A weak basal layer probably exists in areas with a shallow snowpack.
