Regions: Waterton Lakes.

Shifting winds have created variable snow amounts on top of the January crust. Ski quality changes with every few turns.

Upper Waterton lake ice is still very thin and open in some places. Watch for slippery sections on hiking trails close to town.

Weather Forecast

Fri: Clear skies, with alpine temps rising to -4. Winds increasing S-X at ridgetop FL valley bottom.

Sat: Partially cloudy with alpine temps -3. Strong ridgetop winds, FL valley bottom

Sun: Clear skies, alpine temps -4. S-X ridgetop winds, FL valley bottom

Snowpack Summary

4cm HST adding to windslabs ALP/TL. Jan 18 crust extends all aspects up to 2000m. ALP consists of hard windslab in lees and stripped to ground in scoured areas. Well settled midpack over facets above Dec 4 crust, that is beginning to break down, buried 150-200 cm. A 20-60 cm thick Nov melt freeze crust complex completes the snowpack.

Avalanche Summary

Two small natural point releases observed today from steep N facing terrain. No other naturals observed

Confidence

Due to the number of field observations

Avalanche Problems

Wind Slabs

Friday and Saturday's S-X winds will continue to build windslabs in lee features

  • Use caution in lee areas. Recent wind loading have created wind slabs.
  • Keep an eye out for reverse loading created by N-NE winds earlier in the week.

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

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2
