More detailed information about the snowpack: 

Strong SW winds, light snowfall, and blowing were creating new wind slabs in wind loaded areas both above and below treeline on Mt. Tallac. During the mid day hours, new wind slabs ranged from 2 to 6 inches thick and were fairly easily skier triggered on N-NE-E aspects. Skier triggered cracking was common in wind loaded areas above 7,600'.

Warming conditions were occurring under thick cloud cover with increasingly wet surface snow noted on the E aspects traveled in the 7,400' to 6,600' elevation range during the early afternoon hours. Some minor skier triggered roller balls were observed. Wet snow instability in the area today was less widespread than the evidence of recent loose wet instability from yesterday.
