Regions

Waterton Lakes, Waterton.

New snow is skiing well in Waterton however thin conditions still exist near valley bottom so watch for stumps and rocks.

Confidence

Moderate

Avalanche Summary

Several dry loose natural avalanches observed in the last 24 hours.

Snowpack Summary

15cm of new snow in the last 24h. This overlies 30 cm of unconsolidated snow or windslabs in exposed areas. A recently buried thin crust exists on solar aspects. The Feb 3 melt freeze crust is now down ~50cm on all aspects and elevations. This crust is up 30cm thick and has moist snow to ground below it. Snowpack depths between 50 - 200 cm.

Weather Summary

Thurs

Light flurries and overcast skies amount 2-5cm. Alpine high -17°C with light east winds.

Fri

Clear skies and temps rising to -5°C in the alpine. Winds light east.

Sat

Temps continue to rise to -2°C in the alpine. Winds switch back to southwest and will be light.

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.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
