Weather Forecast

Expect a mix of sun and cloud for the forecast period with light flurries possible on Monday evening. Winds should remain generally light with daytime freezing levels sitting at about 1500m.

Snowpack Summary

Light accumulations from Friday may now exist as a soft wind slab in high elevation lee terrain. The new snow overlies older wind slabs, crusts and wind-scoured surfaces. Weaknesses buried in the upper snowpack may include hard crusts and/or weak facet crystals. At the base of the snowpack, weak facets may be found. Cornices are large and potentially fragile. Below treeline, the snow is in a spring melt-freeze cycle.
