Regions

Banff Yoho Kootenay.

There's a lot of variability in the avalanche conditions right now, ranging from frozen crusts and low danger to dry windslabs in the alpine with sluffs and cornice falls. Alpine areas near the Divide are where the highest danger exists. Be ready!

Weather Forecast

2-5 cm more snow is expected to fall overnight Monday before the storm abates making for a total of 10-15 cm from this system. Limited freeze expected in the valley bottoms on Tuesday morning and cloudy most of the day. A ridge of high pressure will build into the area on Wednesday making for a nice day on Thursday,

Snowpack Summary

5-10cm of 24-hour sits on on melt-freeze crusts that can be found on all aspects up to ~2300m and higher on solar aspects. Variable snow depths, and some areas up high on the Divide report up to 30 cm dry surface snow. Consistent winds have formed fresh windslabs. Some loose wet avalanches are expected in afternoons at low elevations.

Avalanche Summary

Numerous avalanches were reported: Cornice on Kindergarten Couloir, avalanche on the Stanley Headwall, sluffs with a partial burial on the Bell Couloir, sluffs on Mt. Victoria. The common thread here is high alpine terrain.

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 Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
