Regions: Jasper.

Wind slabs may be forming in unusual spots due to northerly winds. Ice climbers, watch out for spin drifts from above.

Weather Forecast

Monday:A mix of sun and cloud.Precipitation: Nil.Alpine temperature: High -25 C.Ridge wind east: 15 km/h.Freezing level at valley bottom.

Snowpack Summary

Up to 15 cm of new snow. New wind slabs in the alpine and exposed tree line from strong SW winds and incremental precipitation. Weak temperature crust up to 1900m and solar crust on solar aspects up to 2800m. December facets down 20-70cm, showing signs of rounding within bulletin region. Basal facets & depth hoar present throughout area.

Avalanche Summary

Icefields patrol and Maligne road patrol did not observe any new natural avalanche activity. Visibility was fair overall on Sunday.

Confidence

Due to the number of field observations

Avalanche Problems

Wind Slabs

These slabs are sitting on old hard surfaces (old wind slabs, temperature and sun crusts).

  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Dry

Most concern for ice climbers. Avoid narrow gullies and climbs exposed to steep rocky terrain.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5
