Regions: Jasper.

Small amounts of new snow are adding up to some great winter-like skiing.

Lookout for recent wind loading and sluffing in steep terrain.

Weather Forecast

Tuesday: Cloudy with sunny periods and isolated flurries. Precip: Trace. Alpine temperature: High -9 C. Ridge wind west: 15-35 km/h. Freezing level at valley bottom.

Wednesday: Cloudy with sunny periods and isolated flurries. Precip: Trace. Alpine temperature: Low -10 C, High -6 C. Ridge wind west: 15-35 km/h. Freezing level: 1500 metres.

Snowpack Summary

Up to 25cm new snow from convective flurries over past few days, redistributed by SW winds TL/ALP, overlies a variety of sun crusts on solar aspects up to ALP. The overall snowpack is variable at TL and above with a supportive strong 1F to P midpack in the deeper areas to a weak facetted midpack in shallow areas.

Avalanche Summary

Patrol in the Icefields area observed couple sz 1 wind slab avalanches in ALP wind loaded features.

Avalanche Problems

Wind Slabs

Recently formed wind slabs can be found in lee features near ridge crests, and in cross-loaded gullies.

  • Be careful with wind loaded pockets, especially in steep confined alpine terrain.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2

Loose Dry

Enough new snow has fallen over the past few days to produce Loose Dry avalanches in steep terrain. Use caution in exposed or confined features where small avalanches can have high consequences.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1
