Accumulated new snow is developing into storm slabs. Back off steep terrain if you see evidence of nearby avalanches or signs of instability like cracks in the snow surface.

On Wednesday, in the region's northeast, several natural and remotely-triggered wind slab avalanches up to size 2 were reported from north and east aspects in the alpine and treeline.

As storm snow accumulates, we expect storm slabs to form and become reactive and may trigger old wind slabs at alpine and treeline elevations.

20 to 25 cm of new snow has accumulated over old wind slabs at alpine and treeline elevations, overlying a crust on all aspects and elevations.

A widespread crust with facets above is down 60 to 110 cm. This layer is unlikely to human trigger in areas where a thick crust above the weak layer is present.

Thursday Night

Cloudy with isolated flurries 2 to 4 cm. 10 to 20 km/h east ridgetop wind. Treeline temperature -7° C.

Friday

Mix of sun and cloud with isolated flurries, 2 to 4 cm. 5 to 10 km/h north ridgetop wind. Treeline temperature -3° C. Freezing level 1800 m.

Saturday

Partly cloudy with isolated flurries, 0 to 2 cm snow. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -2° C. Freezing level 2000 m.

Sunday

Partly cloudy. 10 to 15 km/h southwest ridgetop wind. Treeline temperature -1° C. Freezing level 2100 m.

• Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
• The best and safest riding will be on slopes that have soft snow without any slab properties.
• The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
