Avalanche Forecast

Numerous natural, skier, and explosive-triggered avalanches up to size 3.5 have been a daily occurrence for the past week. Several of these avalanches have failed on or scrubbed down to the crust/facet layer buried early in February.

Looking forward, it remains likely that humans could trigger high-consequence slab avalanches.

Up to 100 cm of new snow has accumulated over the last week. Strong winds and mild temperatures during the recent storm has formed touchy slabs. These slabs may sit atop various weak layers, including surface hoar in wind-sheltered terrain, and a thin melt-freeze crust on sun-exposed slopes.

A widespread crust that formed in early February is buried around 80 to 140 cm deep. Facets have been found above this crust. This layer continues to produce many concerning avalanches across the province.

The remainder of the snowpack is generally well-settled.

Sunday night

Mostly cloudy with up to 5 cm of snow. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -12 °C.

Monday

Mostly cloudy with 5 to 10 cm of snow. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Tuesday

Partly cloudy with a trace of snow. 15 to 30 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Wednesday

Sunny. 10 to 20 km/h west ridgetop wind. Treeline temperature -8 °C.

• Keep in mind that human triggering potential persists as natural avalanching tapers off.
• Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
• Remote triggering is a concern, watch out for adjacent and overhead slopes.
• Persistent slabs have potential to pull back to lower angle terrain.
