Primary Problem: Wind Slab
Bottom Line: Human-triggered avalanches are likely on wind-loaded slopes today. Recent snow was drifted into thicker and stiffer slabs which have been easy to trigger, and will remain reactive for at least another day. Avoid slopes steeper than 30 degrees that have recent wind-loading. Seek out slopes sheltered from wind, and consider smaller slopes with clean runouts that minimize the potential size and consequences of a slide. Carefully evaluate the snowpack for recent wind-loading and buried weak layers before getting onto steeper slopes.

Wind slab avalanche on Woodward Mountain, observed on 1/30. Avalanche appeared recent but date of slide is estimated.

From email: "Today I drove down Taylor fork road, with the thought of potentially getting up on woodward mtn, until I saw a crown on the NE
Face of its northern summit, basically wall to wall near the top of  the slide path. There were a couple other sled tracks that also went to the end of the road, so I figured maybe it was pretty recent, as I didn’t hear about it in the advisory. Concerning because it appears to have propagated maybe 250ft across,  while maybe only 1-2 ft deep"
