Regions: Jasper.

Careful evaluation of the snowpack and new surface instabilities is needed meow! Reports of skier triggered avalanches in the surrounding neighborhood is a reminder to all users to be cautious and conservative when riding in these active conditions.

Weather Forecast

Out with one storm and in with another. A short reprieve from snow and broken skies for Monday before a second storm comes in by Tuesday afternoon. Expect 10 - 20cm by Monday morning in the icefields area with gusty SW winds at ridge top.

Snowpack Summary

As of 15:00, 10 cm new snow (and still falling) with Moderate to Strong SW winds. You can assume that this system is actively creating new and overloading existing windslabs. While generally a strong, and supportive snowpack this surface instability will linger and deserves your respect.

Confidence

Intensity of incoming weather systems is uncertain on Tuesday

Avalanche Problems

Wind Slabs

New snow overloading an active wind slab, potentially 30-50cm deep. Predominately on exposed alpine and treeline features. Natural and human triggering likely!
Avoid terrain traps, such as gullies, where the consequences of a small avalanche could be serious.Be careful with wind loaded pockets while approaching and climbing ice routes.

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