    Wet slabs are becoming less likely, but could still occur during rainfall. Glide slabs may also occur where the whole snowpack is sliding on a smooth ground surface, like rock slabs.

Weather Forecast

A cold front arriving overnight and lingering on Sunday brings 10-20 cm snow, with moderate SW winds. The freezing level should fall to around 1100 m by Sunday morning. A mix of sun and cloud, light winds and cool temperatures are expected on Monday and Tuesday.

Avalanche Summary

No recent avalanches have been reported. A few large wet slab avalanches were observed 5-7 days ago. At least one of these failed on a melt-freeze crust down about 30 cm. Most operators have shut down for the season. Please continue to share your backcountry observations through the Mountain Information Network.

Snowpack Summary

As temperatures gradually cool through the weekend, loose wet and wet slab avalanches will become less likely. Storm slabs may develop in the alpine as the cold front passes through. At lower elevations, monitor the overnight freeze of the snow surface. If the snow surface does not freeze overnight or if the crust is thin or breakable, daytime heating or rain will weaken the snowpack much more quickly than if there is a well frozen thick crust. Low elevation and thin snowpack areas are isothermal.
