Regions: Waterton Lakes.

Cornices are large and present right now. Overall the travel is good in the mountains  with some decent skiing on high sheltered northerly terrain.

Weather Forecast

Mon: Mix of sun, cloud and isolated flurries. Alpine high -8 and light NE winds. Freezing level at the valley bottom.

Tues: Sun and cloud. Alpine high -8. Light E winds.

Avalanche Canada's Mountain Weather Forecast is a great regional-scale resource for up-to-date weather information. SPOTWX is a good resource for local scale weather forecasts.

Snowpack Summary

Up to 20cm of new snow  at TL and above on northerly terrain. This sits on a supportive crust that exists to ridgetop except on high north faces (starting to break down mid day). Overall a well consolidated snowpack with the lower half composed of dense facets and decomposing crusts, which haven't produced test results or recent avalanches.

Avalanche Summary

No new avalanches reported or observed.

Please consider submitting a MIN report if you see an avalanches.

Confidence

Due to the number of field observations

Avalanche Problems

Wind Slabs

Pockets of windslab were noted at higher elevation lee terrain that may be reactive to skier traffic.

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Dry

A couple of recent loose dry avalanches were noted out of some large north facing steep alpine terrain.

  • Be careful of loose dry sluffing in steep, confined or exposed terrain.

Aspects: North, North East, East, North West.

Elevations: Alpine.

Likelihood: Possible - Likely

Expected Size: 1 - 1.5
