    Wet slabs could occur during warming. Glide slabs may also occur where the whole snowpack is sliding on a smooth ground surface, like rock slabs.

Weather Forecast

A mix of sun and cloud, light winds and possibly a few convective showers are expected over the next few days. The daytime freezing level stays around 1700 m until Wednesday, when it begins to climb again.

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

Isolated storm slabs may be found in the high alpine. At lower elevations, monitor the overnight freeze of the snow surface. If the snow surface does not freeze overnight or if the crust is only a few cm thick, 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 likely to be isothermal.
