Lo esencial

It will take a few days for recent storm snow to settle and bond. A cautious approach is recommended at higher elevations.

    Recent storm snow has settled into slabs that are likely most reactive at higher elevations and on wind-loaded features.

Confidence

Moderate - Due to the number of field observations

Weather Forecast

SATURDAY: Mix of sun and cloud with isolated flurries, light winds, alpine temperatures around -4.SUNDAY: Cloudy with isolated flurries, light south winds, alpine temperatures around -5.MONDAY: Cloudy with isolated flurries, light southeast winds, alpine temperatures around -6.

Avalanche Summary

On Friday, explosive control produced several size 1.5-2.5 storm slabs on north and east alpine slopes. Human triggering avalanches in the storm snow may remain likely at higher elevations over the weekend.

Snowpack Summary

A warm wet storm delivered 20-40 cm of heavy snow with freezing levels up to 1600 m on Thursday. Expect to find storm slabs at higher elevations, particularly on wind-loaded northeast slopes. At lower elevations moist snow will gradually freeze into a hard crust. The lower snowpack appears to be well settled. There have been isolated reports of surface hoar layers that formed in early January that may still exist about 40 cm deep in sheltered areas. A widespread weak layer of facets from mid-December can be found buried about a metre deep, but is generally considered dormant.
