    New snow may not bond well to an underlying hard crust. Observe for the bond of the new snow before committing to larger or steeper terrain features. If you get the snow moving, it could entrain substantial amounts of snow and travel far.

Confidence

Moderate - Timing, track, or intensity of incoming weather system is uncertain

Avalanche Summary

Although reports are limited in this region there were no signs of avalanche activity around Seymour on Friday, as described in a MIN report here. In the neighbouring Sea to Sky region, many natural and explosive-controlled avalanches have been reported through the last several days in alpine terrain. Similar avalanche activity is likely to be found at high elevations in the South Coast region.

Snowpack Summary

New snow on Saturday and Sunday are falling on a melt-freeze crust that was formed during Thursday’s storm.  The new snow may not bond well to the crust. Expect the deepest deposits in lee terrain features around treeline and alpine elevations.
