    Recent storm snow accumulation over 100 cm may be found at higher elevations. Expect to find even thicker slabs in lee terrain features due to strong winds from the south. Snow amounts from Thursday's storm will rapidly vary with elevation.

Confidence

Moderate - Due to the number of field observations.

Avalanche Summary

No new reports of avalanches in the region. In the neighbouring Sea to Sky region, many natural and explosive-controlled avalanches have been reported through the last several days. Similar avalanche activity is likely to be found at high elevations in the South Coast region.We would very much appreciate it if you spend a moment to submit any observations you have to the Mountain Information Network here, even if it is just a photo. Thanks!

Snowpack Summary

Thursday's precipitation fell as rain at most elevations except for in the alpine near Squamish. Expect to find rain-soaked snow to treeline and storm snow up to 100 cm thick and even deeper in wind-loaded terrain features in the high alpine. Snow depths are over 200 cm in the alpine.
