Weather Forecast

Sunny Wed, then an incoming system bringing snow through the weekend

Today: Cloudy with sunny periods, fzl 900m, light W winds

Thurs: Mainly cloudy with flurries, trace precip, freezing level 1100m, moderate SW winds

Fri: Flurries, 8cm snow, fzl 1400m, 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

One loose/dry sz 1 natural avalanche was observed off the NW side of Lookout Mtn 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.
