Avalanche Forecast
Regions: Waterton Lakes.
The hazard will increase throughout the day as we receive an additional 10-15mm of precipitation. Carefully evaluate how storm snow is bonding to previous surfaces as slab reactivity will vary with elevation. Expect icy roads on the Akamina Parkway
Weather Forecast
Tuesday:10-15 cm of snow at Cameron Lake with wet snow & rain in the townsite. Freezing level 1500m. SW wind 30km/h gusting 80km
Wed/Thurs: Cloudy with sunny periods & isolated flurries. Trace precipitation. Freezing level valley bottom
Snowpack Summary
Up to 15cm of new snow is expected at higher elevations tuesday. Tuesdays storm will form storm slabs over top of old wind slab. Previous wind slab sits on a firm crust below 1900m. We have not found the buried surface hoar that has been causing instability in neighboring regions but this problem may still exist in isolated pockets.
Avalanche Summary
No recent avalanches observed but we expect a natural cycle to occur tuesday/ wednesday. Please post a MIN if you see anything!
Confidence
Avalanche Problems
Storm Slabs
New snow will need time to settle. Bonding of new snow will be variable with fluctuating freezing levels.
- Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 2.5
Loose Wet
Tuesdays storm is forecasted to arrive with high freezing levels. Wet loose avalanches will not be a concern once the temperature begins to drop on Wednesday.
Aspects: All aspects.
Elevations: Treeline, Below Treeline.
Likelihood: Possible
Expected Size: 1 - 2.5
