Avalanche Forecast

Several size 1 (small) avalanches were reported in the alpine on Friday.

Looking ahead, we expect rider-triggerable avalanches to be possible, especially in the alpine where reactive wind slab deposits exist.

Observations have been limited in this region. If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).

Another 10 cm of new snow may have fallen by the end of the day on the 22nd, bringing the 48 hour storm total to 20 cm. Moderate to strong southerly winds are expected to form deeper deposits on north-facing slopes.

In the alpine, an estimated 60 to 100 cm of snow sits above a thin crust. We are not currently concerned about this layer in this region.

Below treeline, a crust or moist snow will likely be observed on the surface.

Snow depths at treeline vary across the region. Around 140 cm is reported in the Coquihalla and 85 cm near Manning Park.

Check out this MIN from Friday.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Be alert to conditions that change with aspect and elevation.
