Avalanche Forecast

Moderate

Riders were involved in a large (size 2) avalanche that they triggered on north-facing slopes off Nak-Thar col on Wednesday.

A small rider-triggered avalanche occurred near Needle Peak on Monday. See photo below.

Looking ahead, natural and human-triggered avalanches are expected in wind-loaded areas.

Observations have been limited in this region. Please consider sharing your observations to the Mountain Information Network (MIN).

Since Saturday, 35 to 55 cm of snow has accumulated at upper elevations, while lower elevations saw mostly rain. Accompanied by strong to extreme southerly ridgetop winds, cornices and wind slabs have likely formed on lee northerly slopes while scouring windward southerly slopes.

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

Snow depths at treeline range from 140 cm in the Coquihalla to 85 cm near Manning Park.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Seek out sheltered terrain where new snow hasn't been affected by wind.
• Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
