Weather Forecast

Unsettled weather bringing incremental amounts of snow over the next few days will not change the danger rating drastically.

Snowpack Summary

< 5cm of new snow over the course of the day accompanied with light wind have generated soft wind-slabs at high elevations. Likely, these wind-slabs are not more than 20cm thick. Furthermore, the Nov 6 crust remains a concern, down 80cm.

Avalanche Summary

No avalanche activity observed or reported today.

Confidence

Intensity of incoming weather systems is uncertain on Tuesday
