Avalanche Forecast

Several small skier-triggered wind slabs occurred at treeline over the weekend into Monday.

A thin crust is on the surface at treeline and below, and into the alpine on sunny slopes. North aspects are expected to be crust-free with some facetting occurring, likely softening the surface.

Surface hoar has been growing in sheltered locations.

The mid and lower snowpack is well consolidated, with several well-bonded crusts scattered throughout.

Snow depth has been reported as 330 cm at 1700 m, tapering quickly at lower elevations below treeline.

Wednesday Night

Partly cloudy. 10 to 20 km/h north ridgetop wind. Treeline temperature -3 °C.

Thursday

Sunny. 10 to 20 km/h southwest ridgetop wind. Treeline temperature +3 °C. Freezing level 2700 m.

Friday

Mostly cloudy with 15 to 25 cm of snow. 40 to 60 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1000 m.

Saturday

A mix of sun and cloud. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -3 °C.

• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
• This is a good time for exploring terrain.
• Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
