    Loose wet avalanches are possible in steep, rocky, sunny terrain. Warming could also wake up more deeply buried weak layers, creating a surprisingly large avalanche.

Weather Forecast

We'll see little change in the weather pattern: valley cloud and cool temperatures down low but sunny and warm up high. SUNDAY: Cloudy with sunny breaks. Light to moderate south-west winds. Freezing level near 1700 m.MONDAY: Sunny with cloudy periods. Light wind. Freezing level near 1500m with an above freezing layer at 3000 m. Alpine high temperatures near +3.TUESDAY: Sunny with increasing cloud in the afternoon. Light wind. Freezing level near 2000 m with a colder air layer in the valleys.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

On Friday, a Size 2 dry loose avalanche was reported at 2300m on a south east aspect near Rogers Pass. A large size 3 natural avalanche was reported on a steep north-facing alpine face in the Selkirks. The failure layer is unknown, but it was likely an early season crust.

Snowpack Summary

Daytime warming will melt and weaken upper snowpack layers, particularly on steep sunny slopes. Warming also has the potential to wake up more deeply buried crust layers which formed in November and October. On the whole, these crusts have been showing reasonable bonding in snowpack and slope tests. Below treeline, the snowpack is shallow--look out for early season hazards like open creeks and tree stumps.
