Regions

Waterton Lakes, Waterton.

Snow is falling again, watch for new storm slabs building on a crust. Many early-season hazards will still exist especially below treeline where the snowpack is rebuilding completely.

Confidence

Low

Avalanche Summary

No new avalanches observed, however poor visibility.

Snowpack Summary

10-20cm of storm snow overlies a rain saturated re-freezing snowpack in the alpine and at treeline. Below treeline, the new snow mostly sits on ground.

Weather Summary

Overnight

An additional 10-15cm is possible

Fri

Flurries through the day 2-5cm. Winds will be light until noon and then increase to moderate NW. Freezing Levels remain valley bottom

Sat

Partially cloudy, alpine temps of -5. Winds increase through the day to strong SW

Sun

Winds Remain elevated strong to extreme SW. Light flurries, overcast and alpine high near -4

Terrain and Travel Advice

Watch for fresh storm slabs building throughout the day.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
