    The base of the snowpack remains weak due to the presence of basal depth hoar and facets. Natural activity is tapering off, however human triggering is still likely on this layer.

Weather Forecast

The trend is for light precip and cooling temperatures over the next few days. Wind will shift to the North on Thursday evening. It could get significantly colder by the weekend. These weather inputs will have little effect on the current danger ratings.

Snowpack Summary

Some wind effect in open areas above tree line. Temperature crust present below 1800m. 60-70cm of well settled snow from recent storms and warm temperatures sits over weak facets and depth hoar at the bottom of the snowpack.
