Regions: Jasper.

The wind is ripping through the forecast region; forecasted to exceed 80 kph by Tuesday afternoon.

Weather Forecast

The colder air is leaving the region as a  westerly flow brings warmer moister air in. Strong winds and light precipitation over the next 24 hrs.

Snowpack Summary

Top 30cm of the snowpack is mostly unconsolidated except where exposed to wind and slabs may have been formed. The snow depth is variable at all elevations. There is a crust/facet layer distributed through the region in the mid-pack with mixed reactivity and a weak basal facet/depth hoar layer at the base of the pack.

Avalanche Summary

No new avalanches observed or reported.

Avalanche Problems

Wind Slabs

Strong SW winds have likely created wind slab in NW to SE lee aspects. Sensitivity expected to be reactive in the immediate future and might be enough to wake deep, weaker interfaces.

  • Be careful with wind loaded pockets while approaching and climbing ice routes.
  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2

Deep Persistent Slabs

A few large avalanches were observed during last cycle early in December and we suspect it was on this layer.

  • Dig down to find and test weak layers before committing to a line.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5
