In sintesi

Strong to extreme W. winds, freezing levels to 2000m and up to 10cm of snow (drizzle at lower elevations) will keep the hazard elevated on Friday. A few large natural avalanches were observed today, and it still feels spooky out there. SH

    The Valentine surface hoar down up to 90cm is overlain by a stiff slab and remains very sensitive to triggers. Natural activity has slowed somewhat,but a few solar releases (Urs Hole) to size 3 were seen. Some slopes have reloaded over the last day.

    The deep facets in the Rockies snowpack are awake again. These have mainly been observed on bigger features where the weight of the initial avalanche triggers the basal depth hoar, causing very large avalanches.
