Points saillants

Watch for changing conditions through different aspects and elevations with both the sun and wind this weekend. Windslabs will be most likely near ridgecrests and the new snow will slide easily on solar slopes once the sun comes out.

Avalanche Summary

No new avalanches observed.

Snowpack Summary

Up to 10 cm of new snow covers sun crusts on solar aspects and consolidated dry snow on polar aspects. Below this the March 21st crust exists everywhere except for polar aspects above ~2000 m. The Feb 3rd crust/facet weak layer is buried 60-120 cm deep. Below this, the snowpack consists of a mixture of settled snow and crust/facet layers to ground. Snowpack depths between 80 - 250 cm.
