Avalanche Summary
Warm temperatures and light to moderate precipitation resulted in several low-elevation natural storm slab avalanches up to Size 1.5 on Monday. Storm slabs continue to be reactive to natural and human triggers.
Snowpack Summary
Total snowpack depths are well above average for this time of year and it won't stop snowing! Recent warm temperatures and upside-down storms created a touchy surface slab. Other weaknesses within and under the 150+cm of recent storm snow create the potential for step-down avalanches, but things seem to be settling rapidly. Strong winds associated with recent storms means large weak wind slabs and cornices on lee and cross-loaded terrain. Most snowpack concerns are limited to the surface layers, however large triggers such as cornice falls and smaller avalanche stepping-down could reawaken deeper persistent weaknesses.
