Lo esencial

The weather forecast calls for a mix of sun and cloud, yet relatively cool temperatures. Minimize your exposure to sunny slopes when the sun is out for extended periods.

    The sun really packs a punch this time of year - that's no April Fool's joke! Limit your exposure to sunny slopes if the sun comes out in full force.

Snowpack Summary

We've seen only small amounts of new snow (1-8cm) in the past two days with daytime high temperatures rising to just above freezing at tree line elevations. The end result has given us a ~3cm thick melt-freeze crust that is generally unsupportive at lower elevations (below tree line) and supportive at higher elevations (tree line), particularly in the North Shore mountains. Alpine areas around Squamish likely received about 60-100 cm of storm snow and more wind early in the week. In these areas the storm 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.

Confidence

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

SUNDAY: A mix of sun and cloud with isolated flurries / Light to moderate west wind / Alpine temperature -1 / Freezing level decreasing to 500m MONDAY: Mix of sun and cloud / Light to moderate south wind / Alpine temperature -1 / Freezing level 500m
