Avalanche Forecast

Moderate

Only a few natural size 1.5 wind slab avalanches have been reported over the past few days.

Over the past week in the neighbouring region, many natural and skier triggered persistent slab avalanches occurred on the facets above the early-February melt-freeze crust described in the Snowpack Summary.

Winds have come from a variety of directions over the past couple days. Wind effect could be found on all aspects. A crust or moist snow will be found on south and west facing slopes.

30 to 50 cm overlies a layer of surface hoar in wind-sheltered terrain, weak facets, or a hard melt-freeze crust on south and west-facing slopes.

A thick and hard widespread crust that formed in early February is buried about 60 to 80 cm deep. This crust may have a layer of facets above it.

The eastern portion of this region is much shallower with a highly variable and wind effected snowpack.

Monday Night

Mostly clear skies. 10 to 20 km/h west alpine wind. Treeline temperature  -22°C.

Tuesday

Sunny. 10 to 20 km/h west alpine wind. Treeline temperature -10°C.

Wednesday

Mostly sunny. 5 to 20 km/h southwest alpine wind. Treeline temperature -8°C.

Thursday

Increasing cloud with trace amounts of new snow. 25 to 50 km/h southwest alpine wind. Treeline temperature -4°C.

• Conservative terrain selection is critical, choose only well supported, low consequence lines.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
• Remote triggering is a concern, watch out for adjacent and overhead slopes.
• Avoid sun exposed slopes, especially if snow surface is moist or wet.
