Regions

Glacier.

Thin snow coverage is the biggest hazard at the moment; expect to hit rocks, stumps etc. in most areas if attempting to ski/board. If snow cover is sufficient to link turns, avalanches are a possibility. Daily avalanche forecasts begin November 1st.

Weather Forecast

Snowfall and a warmer temps gives way to clearing skies and slightly cooler temps for the weekend.

Snowpack Summary

Below treeline the snow hasn't really started to cover any of the surface roughness. As you transition through treeline and into the alpine 1 meter (and counting) of settled snow has formed the beginning of this seasons snowpack.

Avalanche Summary

Heavy snowfall triggered a cycle of large avalanches yesterday (Oct. 28th). Many of these ran into the rugged ground cover below treeline - a good reminder that even a small avalanche could have severe consequences if it drags you through an alder/ boulder field.

Please report any avalanche activity observations on the 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.

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.
