Avalanche Forecast

Moderate

Reactive storm slabs likely exist on Friday.

No persistent slab avalanches have been reported since early February.

If you are traveling in the mountains, consider posting to the MIN.

Up to 30 cm of new snow accompanied by strong southerly wind has formed new storm slabs. Wind loading has likely formed deeper slabs on northerly facing slopes. These sit over firm, wind-affected surfaces in exposed areas, faceted snow in sheltered terrain, and a crust on steep solar aspects. A poor bond to these interfaces may exist.

A weak layer of facets and a crust from early December is buried 60 to 150 cm deep. This layer exists on all aspects up to 1750 m. This layer has not been active in producing avalanches or test results in several weeks and is generally not a concern at this time.

At the highway elevation, the snow depth is 120 cm, and in the alpine exceeds 200 cm.

Thursday Night

Cloudy with 3 to 5 cm of snow. 40 to 80 km/h south ridgetop wind. Treeline temperature -6 °C.

Friday

Cloudy with sunny breaks and 5 to 10 cm of snow. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Saturday

Mix of sun and cloud with isolated flurries. 15 to 45 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Sunday

Mix of sun and cloud. 10 to 25 km/h southwest ridgetop wind. Treeline temperature -2 °C.

• Keep your guard up as storm slabs may remain sensitive to human triggering.
• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Use conservative route selection. Choose simple, low angle terrain with no overhead hazard.
