One large slab avalanche (size 2.5) was seen from a steep south aspect. Reports suggest it was several days old.

Wind slabs continue to linger in the region, with reports indicating they are stubborn to rider triggering.

Observations remain limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network.

Surface conditions vary from wind affected surfaces in exposed terrain at higher elevations, and settling snow in sheltered areas that may include a layer of surface hoar buried 5 to 10 cm deep. Warmer temperatures will likely affect the surface snow and produce a crust overnight.

The mid snowpack is generally well settled, with an early November crust buried 50 to 100 cm deep. This layer is understood to be more notable in the Selkirk Mountains.

Snow depths at treeline are roughly 80 to 150 cm, and decrease rapidly at lower elevations.

Tuesday Night

Partly cloudy. 15 to 40 km/h west ridgetop winds. Treeline temperatures around -5 °C with an above-freezing layer bringing the alpine temperatures to 0 °C.

Wednesday

Cloudy with sunny periods. 15 to 30 km/h southwest ridgetop wind. The above-freezing layer brings alpine temperatures around +1 °C. Treeline temperatures near -2 °C.

Thursday

Cloudy with isolated flurries possible for the Cariboos. Sunnier skies further south. 20 to 40 km/h southwest ridgetop wind. The above-freezing layer brings alpine temperatures around +2 °C. Treeline temperatures near -1 °C.

Friday

Mostly cloudy. New snow 5 cm. 15 to 35 km/h southwest ridgetop wind. Alpine temperatures near -3 °C.

Wet loose avalanches (size 1.5 to 2) were naturally triggered by the sun on steep sun-exposed terrain at treeline and alpine near Whistler in the last two days.

Warming signs of instability such as tree bombs and pinwheels were observed throughout the region this past weekend.

If you are going out in the backcountry, please consider filling out a Mountain Information Network (MIN) report.

A melt-freeze crust has likely formed at the snow surface due to overnight cooling. Rising temperature will start to melt the snow surface, as the day progresses, especially on steep sun-exposed slopes.

Alpine slopes are wind-affected, scoured, or hold a thin surface crust. In sheltered terrain at treeline, large weak surface hoar crystals may still be persisting under 15 cm of moist snow.

Snow depths vary from 100 to 140 cm at treeline and decrease rapidly below 1500 m, exposing early-season hazards.

Tuesday Night

Mostly clear. 10 to 20 km/h west ridgetop wind. Treeline temperature +4 °C. Freezing level 2500. Alpine temperature inversion.

Wednesday

Mix of sun and cloud. 10 to 20 km/h southwest ridgetop wind. Treeline temperature +6 °C. Freezing level 3000 m. Alpine temperature inversion.

Thursday

Mostly cloudy. 20 to 40 km/h southwest ridgetop wind. Treeline temperature +4 °C. Freezing level 2500 m.

Friday

Cloudy with heavy precipitation either rain or snow. 40 to 60 km/h south ridgetop wind. Treeline temperature +4 °C. Freezing level 2500 m.
