Avalanche Summary
Many parts of the region will not receive enough new snow for avalanches, however, a variable wind and snowfall pattern may form localized wind slabs.
Snowpack Summary
A cold front crossing the south Purcells and Rockies is causing variable snowfall and wind-loading patterns. Expect anywhere from 0 to 20 cm of new snow above a widespread crust. The heaviest amounts as of Tuesday afternoon were north of Crowsnest Pass and Elkford, but more scattered flurries are expected on Tuesday night.
The upper snowpack consists of various melt-freeze layers. The lower snowpack contains old weak layers that are no longer a concern.
