Kernpunkte

Scoured alpine terrain may push eager skiers into loaded gullies and lee terrain where the possibility of triggering windslabs exists. The Jasper Visitor Safety team wishes everybody a safe and happy holiday season!

    Previous strong winds have created a mosaic of snow depths across the landscape. These slabs will vary greatly in their sensitivity to triggering and requiring each slope to be evaluated carefully.

    The depth of this crust is now highly variable, and may be as deep as 1m in lee areas that have received significant loading due to strong SW winds. Careful evaluation of this interface is essential.

Weather Forecast

Light snowfall amounts, gradual rise in temperature and light winds from the SW forecasted for Tuesday, with an Alpine high of -12. Light scattered flurries and seasonal temps to wrap up 2016.

Snowpack Summary

Up to 15cm of settling storm snow may be found in sheltered areas. Moderate SW winds have built slabs in lee features and cross loaded gullies. Weak layers include; buried surface hoar (Dec 11) in sheltered NE aspects around treeline (2100-2300m) and the Nov 12 crust approximately 30cm from the ground.

Avalanche Summary

No new avalanche observations or reports.
