Avalanche Forecast
Regions: Babine, Hudson Bay, Microwave-Sinclair, North Bulkley, South Bulkley, Telkwa.
Assess for warming-related avalanche problems this weekend. New snow on Monday could form small wind slabs on alpine slopes.
This is the final daily avalanche forecast for the season.
Confidence
Moderate
Avalanche Summary
We haven't received any recent reports of avalanche activity.
Wet loose avalanches and cornice falls are possible this weekend with daytime warming. Monday's storm may form small wind slabs in the alpine and continue wet loose activity at lower elevations.
Please consider sharing your observations to the Mountain Information Network.
Snowpack Summary
A hard melt-freeze crust is found on the snow surface everywhere except perhaps in the high alpine, where a dusting of dry snow may be found. The crust will soften with daytime warming. Monday's storm may build new slabs in the alpine.
Two weak layers that formed in February and March are found in the middle of the snowpack. These layers haven't produced any recent avalanches, but they could be triggered with a large load, such as a cornice fall.

Terrain and Travel Advice
- Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
- Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
- Carefully evaluate steep lines for wind slabs.
Avalanche Problems
Cornices
Cornices may weaken with daytime warming. A cornice fall could trigger slabs on slopes beneath them.
Aspects: North, North East, East, North West.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1.5 - 2.5
Loose Wet
Wet loose avalanches are possible out of steep terrain with daytime warming.
Aspects: East, South East, South, South West, West.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 2
Wind Slabs
Small wind slabs could form over the day on Monday with new snow and strong wind.
Aspects: North, North East, East, North West.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 1.5
