South Coast

Brief periods of sunshine could destabilize the surface snow on Sunday morning. Be alert for lingering wind slabs up in the alpine in the north of the region.

Moderate - Timing or intensity of solar radiation is uncertain on Sunday

There may be sunny breaks on Sunday morning before some convective flurries in the afternoon, with brief periods of intense precipitation. Temperatures are staying cool for this time of year. SUNDAY: A mix of sun and cloud with convective flurries in the afternoon (3-5cm possible) / Light to moderate south west wind / Alpine temperature -6 / Freezing level decreasing to 500m in the afternoonMONDAY: Mix of sun and cloud / Light to moderate west wind / Alpine temperature -5 / Freezing level 700m TUESDAY: Cloudy with sunny periods / Light west wind / Alpine temperature -5 / Freezing level 800m.

A few wet loose natural avalanches to size 1 were reported on sunny aspects on Saturday. We'd expect the same on Sunday with warming temperatures and direct sun.

At tree line and below, we're into a spring cycle with a good re-freeze overnight (supportive crust) followed by daytime warming to +6 and wet surface snow. New snow amounts over the past three days (1-8cm) have been absorbed into the spring snowpack cycle. Alpine areas around Squamish likely received about 60-100 cm of storm snow and more wind early last week. In these areas the more recent snow is possibly sitting on a mixture of weak grains including a crust on solar aspects and potentially facets/surface hoar on polar aspects. Below the storm snow the snowpack is generally well settled and strong.
