    Rain falling on recent snow will likely trigger wet loose avalanches. Manage sluff carefully—wet snow can entrain significant mass.

Moderate

Avalanche Summary

New avalanche problems will develop Thursday afternoon, with wind slabs forming above the snow line and wet loose avalanches below.

A few small (size 1) skier-triggered slabs were reported on Mount Seymour on Tuesday.

Snowpack Summary

Climbing freezing levels are turning recent snow wet. Freezing levels will peak near 2000 m on Thursday morning before dropping in the afternoon as a windy storm brings 10 to 20 mm of precipitation. Expect rain up to at least 1500 m, with increasing, wind-affected snowfall at higher elevations.

Lower elevations are melting out quickly.
