Kernpunkte

It's still early in Waterton, we probably have enough snow to ski however the snowpack is very young. Travel with an assessment mindset as the snowpack adjusts to all these new loads. Below treeline will still be very thin with early season hazards like stumps logs and rocks.

    May be a concern if recent windslabs step down through the bridging crust.

Low

  • Uncertainty is due to limitations in the field data.

Avalanche Summary

No new avalanches observed however limited observations

Snowpack Summary

Up to 50cm of storm snow from the week snow has been redistributed by strong winds in the alpine and at treeline. This sits atop a new crust from this weeks warm weather and rain. Our midpack is 80-100cm of refreezing snow. At 1700 m and above, the base of the snowpack consists of a series of crusts and facets to the ground. Below 1700 m the snowpack still very thin and some areas will only have this most recent storm snow on ground.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
