Regions

Glacier.

Pockets of wind slab are catching skiers off-guard in the alpine. Specific terrain features (ie steep, wind-loaded slopes) are failing under a person's load.

Weather Forecast

A series of lows will bring a string of weak storms over the next few days.

Today: Cloudy, isolated flurries, trace precip, alpine high -6*C, fzl rising to 1400m, mod SW winds

Tues: Cloudy, scattered flurries, 5cm snow, alpine high -6*C, fzl rising to 1400m, mod SW winds

Wed: Flurries, 5-10cm snow, alpine high -6*C, fzl 1200m, mod/strong SW winds

Snowpack Summary

~10cm of overnight snow has covered up yesterday's suncrust on solar aspects. Storm slabs from the ~60cm snow over the past week seem to be settling and bonding, but periods of moderate to strong southerly winds have created pockets of windslab on lee features, especially on northerly aspects.

Avalanche Summary

Saturday, skiers in the Forever Young couloir triggered a size 2 avalanche which resulted in partial burials and serious injuries. Skiers also triggered avalanches on NRC, Video Peak and Grizzly Couloir. this past week.

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.
