Regions: Jasper.

Monitor your partner for frostbite. Ski conditions are still meager. Early hazards exist everywhere just under the snow. 

Weather Forecast

Expect light flurries with 2-10cm of snow the next few days. Temperatures will warm slightly but remain in the frigid zone.

Snowpack Summary

Variable windslabs on lee features at all elevations. Cold temperatures creating surface facets as a potential future sliding surface. Snow depth is quite variable across the terrain. Deeper areas exist where windloading has occurred. Winds recently gusting to 70km/hr NW further buffing the snow surface. Basal rain crust exists sporadically. 

Avalanche Summary

Icefield's highway patrol with excellent visibility revealed no new avalanches.

Confidence

Due to the number of field observations

Avalanche Problems

Wind Slabs

Variable windslabs continue to form with moderate to strong winds. Be observant where this slab is building.
Be careful with wind loaded pockets while approaching and climbing ice routes.

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Persistent Slabs

Observations are limited for this layer. If triggered, it has the potential to scrub to ground increasing the consequence.   
Cold temperatures have stabilized the snowpack, but watch out for frostbite.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3
