Regions: Glacier.

High quality skiing and riding in sheltered areas tree line and below. Expect to find pockets of wind slab as you venture higher into the alpine.

Weather Forecast

The last day of February will bring mainly cloudy skies, isolated snow flurries and periods of sun. Temps will range from -4 to -10 and winds will be 20-35km/h from the south. 5-10cm of snow forecasted for Friday with freezing levels rising to 1500m

Snowpack Summary

8cm of new snow overnight and ~40cm of storm snow now buries a facet layer, making for a weak bond. Recent moderate to strong southerly winds forming pockets of wind slab in the alpine and tree line areas. A crust is down 30-50cm on solar aspects and the mid January persistent weak layers are buried 150-200cm.

Avalanche Summary

Several regular performers produced natural avalanches up to size 2.0 yesterday along the highway corridor.No new avalanches observed or reported from the backcountry yesterday.

Confidence

Avalanche Problems

Wind Slabs

Incremental snow fall amounts and recent moderate, gusting to strong southerly winds have created pockets of wind slab in the alpine and exposed areas at tree line.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.If triggered the wind slabs may step down to deeper layers resulting in large avalanches.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2.5
