Regions

Glacier.

As stated everywhere in the media, stay home and kick the COVID pandemic. If you just can't sit, then play it very conservatively in the backcountry and choose mellow slopes to travel upon.

Weather Forecast

A mixture of flurries and sun over the next few days.

Today: Mix of sun and cloud with flurries, trace precip, freezing level 1300m, light W winds

Wed: Sun and cloud, freezing level 700m, light W winds

Thurs: Cloudy with flurries, trace precip, fzl 900m, mod W winds

Snowpack Summary

5-10cm of storm snow overlies a crust on solar aspects (SE through W) into the alpine. The new snow sits on surface hoar on shaded, polar aspects. Previously wind-affected surfaces at tree-line and alpine elevations vary from breakable to rockhard/impenetrable.

Avalanche Summary

Two natural slab avalanches to sz 2.5 were observed from extreme terrain on the N side of Macdonald yesterday.

Please report backcountry avalanche observations using the Avalanche Canada Mountain Information Network.

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.
