Points saillants

Spring Conditions. Looks like a typical spring day with a mix of conditions. The sun can be very strong at this time of year; conditions may change rapidly if the sun comes out.

    If the sun comes out, it wont take long for solar aspects to heat up and result in natural cornice falls.

    Loose wet avalanche activity is expected to increase with exposure to strong solar radiation and climbing freezing levels.

Weather Forecast

Mostly cloudy overnight with moderate southwest winds, light precipitation, and freezing levels down to 1000 metres. Mix of sun and cloud on Friday with scattered convective flurries and daytime freezing levels at 2000 metres. A strong ridge develops on Saturday bringing clear skies, light southerly winds and freezing levels up to at least 2200 metres. The ridge gets stronger on Sunday, temperatures and freezing levels sky-rocket to at least 3000 metres.

Avalanche Summary

No new avalanches reported.

Snowpack Summary

The snow surface is currently going through a typical spring melt-freeze cycle on all aspects and at all elevations, except possibly high true-north slopes which could be holding onto cold snow. Forecast new snow and wind are expected to develop new windslabs in the alpine and at treeline. Higher elevations may feel more like winter for another day, and new wind slabs may not bond well to the old hard re-frozen surface.
