Avalanche Forecast

Moderate

Expect avalanche activity to be widespread as this new storm dumps a large amount of snow over a thin, early season snowpack.

So far this season no avalanches have been reported on the Island.

Please consider filling out a MIN report if you are out in the backcountry.

Up to 50 cm of new snow has introduced rapid change to the thin, early season snowpack. In the alpine and upper treeline the new snow could form rider triggerable storm slabs on specific slopes that are above threshold.

The new snow is falling on a variety of early season surfaces, including crusts and 5-15 cm of recent snow. Previously, snowpack height at treeline currently ranged from less than 30 cm at Mt Arrowsmith to around 50 cm in Strathcona Park to 30 cm at Mt Cain. Snowpack depths are deeper in areas that have been wind loaded like gullies and sheltered pockets below ridgelines. Below treeline was mostly snow free before this storm.
