Comments
First time in Millcreek this season and storms from late last week and Tuesday night have greatly helped coverage in this area. I essentially found similar conditions to DB's observation from 12/14 - same structure as found in the Cottonwoods, but just a shallower snowpack. Despite not seeing any avalanche activity, the collapsing is definitely a red flag and will continue to make me wary on the northwest thru east aspects where the PWL is present.
The North American Danger Scale identifies three components to a danger rating: 1. Likelihood; 2. Size and Distribution; and 3. Travel Advice. Although the likelihood of avalanches today was more aligned with a Considerable danger rating, recent avalanches, poor snowpack structure, and heavy snow overnight made for travel advice following the High danger rating where travel is not recommended in avalanche terrain where the PWL is present.
Today's Observed Danger Rating
