Regions: Waterton Lakes.

Snow and ice are disappearing especially near town.

Evaluate temperatures closely when choosing your skiing and climbing objectives for the day.

Higher elevation ice on north aspects is still in good shape.

Weather Forecast

Friday: Clear skies, alpine temps climbing to -2. Winds moderate SW, FL 1500m

Saturday: Clear skies, alpine temps  climbing to -2. Winds moderate SW, FL 1500m

Sunday: Partially cloudy, alpine temps climbing to +2. Winds light to moderate SW, FL 2200m

*Uncertainty exists around forecasted temps. Expect the east side of the park to be warmer.

Snowpack Summary

Warm temps and X-westerly wind has built 20- 40 cm windslabs in lees. Moist snow to approximately 2000m on Thursday's warm up. This overlies Jan 18 crust extending all aspects up to 2000m, and higher on solar aspects. Well settled midpack, with facets above Dec 4 crust, buried 150-200 cm, above Nov layers.

Avalanche Summary

A few small wet loose avalanches observed during peak warming on Thursday. Please post any avalanche observations on the Mountain Information Network, we really appreciate any observations.

Confidence

Timing or intensity of solar radiation is uncertain

Avalanche Problems

Loose Wet

This problem will re-emerge on sunday as the temps are forecasted to climb again. Should temps exceed the forecast, before then, use caution around steep solar slopes.

Aspects: South East, South, South West.

Elevations: Treeline, Below Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Wind Slabs

Warm temps have caused settlement in the snowpack at lower elevations. Windslabs still exist in higher terrain, especially on polar slopes.

  • Avoid steep lee and cross-loaded slopes

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
