Avalanche Forecast
Regions: Banff Yoho Kootenay.
Increased loose wet activity is possible Friday with forecasted clear skies and 2200m freezing levels.
Weather Forecast
Decent refreeze forecasted for Thursday night with a clearing trend into Friday. Slightly warmer temps Friday with freezing levels climbing to 2200m. Upper elevation winds are expected to stay in the light to moderated range from the SW.
Snowpack Summary
Recent storm snow has settled quickly. Where this new snow has not melted away it overlays crusts that exist on all aspects below 2300m and high into the alpine on solar aspects. High N aspects still hold dry powder and some wind effect on lee slopes. Crusts are breaking down and reforming almost daily depending on solar input and freezing levels.
Avalanche Summary
No new avalanches observed or reported today.
Confidence
Avalanche Problems
Loose Wet
Treeline and below will likely deteriorate by the PM, and higher on solar aspects. This includes breakdown of crusts and/or warming of the 5-15 cm of recent storm snow.
- Daytime warming will weaken surface layers.
- Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Possible
Expected Size: 1 - 2
Storm Slabs
The recent storm snow has settled quickly. We have limited observations of how this new snow is bonding to the old surface. The main concern for this problem is at upper elevations predominately on Northerly aspects.
Aspects: All aspects.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 1.5
