Avalanche Forecast

Multiple new wet loose and glide slab avalanches (Size 1 to 2) have been reported in the Coquihalla and Fraser Valley area from the warming period on Saturday.

Thank you to all our recent MIN submissions.

Up to 30 cm of wind affected snow is topped by a variably breakable crust caused by recent strong winds and above freezing temperatures. Moist snow lays beneath this. The trace new snow on Sunday was showing a good bond to this surface.

The mid and lower snowpack contains various old crusts and is generally well-settled and stable.

Sunday Night

Mainly cloudy with 2 to 5 cm of snow at higher elevations. Alpine wind south, 20 km/h. Treeline temperature -1 °C. Freezing level 1500 m.

Monday

Mainly cloudy with 5 to 10 cm of snow at higher elevations. Alpine wind southwest, 20 to 30 km/h. Treeline temperature -1 °C. Freezing level 1500 m.

Tuesday

Mainly cloudy with mixed precipitation, around 5 cm of snow at higher elevations. Alpine wind southwest 30 to 40 km/h. Treeline temperature +1 °C. Freezing level rising to 1600 m.

Wednesday

Mainly cloudy with trace precipitation. Alpine wind southwest 20 to 30 km/h. Treeline temperature 0 °C. Freezing level 1000 m to 1500 m.

• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
• A crust on the surface will help bind the snow together, but may make for tough travel conditions.
