What a storm! Overnight totals are roughly 12-20 inches (0.80-1.50 water) of new snow across much of the range. Upper Big Cottonwood squeezed the most juice with 33 inches of new snow (2.25 water). Winds blow west-northwest at 15-20 mph gusting into the 30s. Mountain temperatures range from 15-22 °F.
This morning under a Winter Weather Advisory, it will continue to snow into the late morning hours with an additional 2-4 inches of snow before tapering off and becoming more showery this afternoon. We might even see some sunshine if you're in the right spot. Temperatures will climb into the low to mid-20s °F. Winds will begin to back to the southwest around lunchtime and blow 10-20 mph, gusting into the 20s and 30s ahead of yet another storm this evening into Monday, where we could see 10-18 inches of new snow once again.
Yesterday's avalanche activity revolved around the strong southerly winds blowing and drifting snow into dense slabs (wind slabs) that were mainly 10-20 inches deep and up to 125' wide. Out of the ten reported avalanches, the most impressive was from Days Fork and Broads Fork. In Days Fork, a cornice failed naturally and triggered a hard slab roughly 2-3 feet deep and 150 feet wide.
In Broads Fork, a natural glide avalanche failed roughly 10 feet deep and 125 feet wide, running to the valley bottom. This avalanche would have ruined anyone's day, and luckily it happened when no one was around. Be sure to read all the observations and recent avalanche activity
