Avalanche Forecast

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

We're looking at mostly sunny weather for Monday, before the next major system arrives on Wednesday. Temperatures are staying cool for this time of year. MONDAY: Mix of sun and cloud / Light to moderate north-west wind / Alpine temperature -5 / Freezing level 800m TUESDAY: Cloudy with light flurries / Light west wind / Alpine temperature -5 / Freezing level 900m.WEDNESDAY: Snow (5-15cm) / Moderate south west wind / Alpine temperature -4 / Freezing level rising to 1200m in the afternoon

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.On Friday a size 1.5 slab avalanche was reported on the south face of the First (aka Pump) Peak on Mt Seymour, which is a heavily traveled slope. See here for a great photo.

At tree line and below, we're into a spring cycle with a good re-freeze overnight (supportive crust) followed by daytime warmings to +6 and wet surface snow. New snow amounts over the past several days (10 cm or less) have been absorbed into the spring snowpack cycle. Alpine areas around Squamish likely received about 60-100 cm of storm snow a week ago, with 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.
