Regions: Jasper.

Cooler forecasted temperatures and overcast skies should keep the spring snowpack frozen at treeline and above. If there is a crust below treeline, expect it to break down early and the snow to go isothermal.

Confidence

Intensity of incoming weather systems is uncertain

Avalanche Problems

Loose Wet

Expect the melt freeze crust to deteriorate rapidly below treeline, with the warm, rainy conditions which are in the forecast through the weekend. Loose snow avalanches are possible below treeline if we receive heavier than predicted showers.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Deep Persistent Slabs

Cooler temperatures in the high alpine should freeze the snowpack tight bridging this weak layer. Pay attention to overhead hazards IF the sun comes out for an extended time as this could rapidly increase the avalanche danger

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 2 - 4
