Observation: Turnagain
Location: Eddies
Standard Eddies uptrack. Much more new snow than expected.
Events of the day
There was a skier-triggered avalanche on the steep westerly rollover that often avalanches. I didn't see the avalanche go, but tracks suggest it was triggered by a skier who skied off the slab at the crown without being carried. 2-3 feet deep crown, debris ran across the next bench into a hemlock patch and over the next rollover.

Observer Comments
New warm snow nearly 2 feet deep, active wind-loading until early afternoon, whumphing while setting the uptrack, avalanche crowns on most steeper west and south aspects, and most concerning, avalanches on smaller, lower-angled slopes down the northwest shoulder that propagated widely on terrain that didn't even look like avalanche terrain. Also a train buried in an avalanche.
Weather
Warm, partly cloudy. Windy enough to blow snow on the Ridgeline until early afternoon and then calm.
Snow surface
20-24 inches new snow.
