Avalanche Rating

Moderate (2)

Valid Tue Dec 3 4:00pm PST 9 hours ago Until Wed Dec 4 4:00pm PST

Wet loose avalanches may become a problem on steep slopes, where the surface is found wet.

The continued mild temperature has consolidated the early-season snowpack.

Snowpack Discussion

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.

Avalanche Activity

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.
