Points saillants

Warm daytime temperatures combined with direct radiation could increase the avalanche danger quickly on solar aspects.

    Triggering this weakness requires a large load (such as a cornice) in areas of deeper snowpack but could be triggered by skiers hitting the weak spot in a shallow snowpack.

Weather Forecast

Light snow flurries will occur on Wednesday and Thursday nights. Only a few centimeters of snow are expected. The winds will gradually shift to the NE by Friday. Temperatures are expected to warm during the day, but remain cooler overall with the freezing level staying below 1400m for the next few days.

Snowpack Summary

A sun-crust is present on solar aspects up to 2300m. A supportive mid pack consisting of rounded and facetted layers is bridging the weak depth hoar/facet layers that make up the lower snowpack.

Avalanche Summary

No new avalanches were observed or reported today.

Confidence

Timing or intensity of solar radiation is uncertain on Friday
