Avalanche Forecast

No new avalanches have been observed or reported in the region. Observations are limited at this time of year, if you head into the backcountry consider submitting a MIN report.

Weekend snowfall accumulation ranged from 10-15 cm near the Duffy and upwards of 35 cm around the Coquihalla and south. This snow mostly covered a crust (or bare rock) at upper elevations and moist snow and dirt at treeline and below.

Below the crust is 40-80 cm of early November snow, which began covering surface roughness at upper elevations. The strength of this basal interface will become more evident with more field observations.

Terrain features poke through a building snowpack that grows from 40-60 cm around 1300-1400 m and upwards of 120 cm in the alpinee. Most solar slopes and below treeline are below the threshold for avalanches.

Monday night

Clear and cold with increasing clouds. Light northeast wind, treeline low temperatures -20 C.

Tuesday

Cold. Flurries start in the afternoon, with substantial accumulations beginning overnight. Increasing south wind, treeline high temperature -12 C.

Winter storm beginning late Tuesday with precipitation likely falling as snow at most elevations. 10-15 mm by morning and another 10-15 mm through the day, South wind gusting above 60 k/h. Treeline high -10 C, freezing level staying below valley bottom.

Cold and clearing. Light northeast wind, treeling high temperature -16 C.

• Watch for areas of hard wind slab on alpine features.
• Seek out sheltered terrain where new snow hasn't been wind-affected.
• Approach lee and cross-loaded slopes with caution.
