Avalanche Forecast

There was an explosives triggered size 2 wind slab avalanche reported on Thursday in the southern portion of the region. This ran on facets buried in early January.

There were a few natural wind slab, storm slab and dry loose avalanches to size 1 and 1.5 reported on Wednesday and Thursday.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

Recent new snow has accumulated over faceted snow and/or previously wind-affected snow. Expect current south west wind to transport this new snow onto north aspect lee terrain. At treeline and below there is a weak layer of facets over a crust, down 40 to 80 cm. This layer was reactive to skier triggering primarily on east aspects between 1500 and 2000 m last week in the south of the region.

The mid and lower snowpack contains a series of crusts and faceted snow.

The height of snow at treeline is roughly 80 to 150 cm.

Friday

Mostly cloudy, trace amounts of snow, southwest alpine wind 20 to 40 km/h, treeline temperature -11 °C.

Saturday

Mostly cloudy with isolated flurries, southwest alpine wind 20 to 50 km/h, treeline temperature -7 °C.

Mostly cloudy with 1 to 3 cm of snow, southwest alpine wind 15 to 30 km/h, treeline temperature -5 °C.

Mostly cloudy with isolated flurries, southwest alpine wind 10 to 30 km/h, treeline temperature -1 °C.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
• Recent wind has varied in direction so watch for wind slabs on all aspects.
