Avalanche Summary
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.
Snowpack Summary
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.
