Regions

Waterton Lakes.

The avalanche hazard is low but pockets of wind slab can still be found on lee slopes in the alpine.

A dusting of new snow wednesday  coupled with moderate winds has created and ideal conditions for wind transport at higher elevations.

Weather Forecast

Friday: Cloudy with sunny periods and isolated flurries. Moderate SW wind. Freezing level 1500m.

Saturday: Mainly cloudy with isolated flurries. Moderate SW wind with strong gusts. 0-2cm snow. Freezing level dropping to valley bottom.

Sunday: Cloudy with scattered flurries. Up to 5cm of snow in the Cameron Lake area with trace amounts in townsite.

Snowpack Summary

5cm of snow on wed night has been redistributed by Moderate SW wind. Reactive wind slabs may be found in isolated lee areas in the alpine. A crust exists below 1900m that varies from bulletproof to breakable dependent on aspect and elevation. Areas east of the divide hold a thinner & more faceted snowpack.

Avalanche Summary

No recent avalanches observed, post a MIN if you see anything!

Confidence

Timing of incoming weather systems is uncertain on Sunday

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
