Good morning, this is

Yesterday morning’s cold
front blasted through with snowfall rates of several inches per hour. It quickly laid down a foot to a half of snow
in the north part of
Recent Avalanche Activity & Snowpack Discussion:
Not surprisingly, yesterday
morning’s intense snowfall and wind produced a widespread cycle of sluffs and
occasional soft slab avalanches within the new snow on most steep slopes. (PHOTOS) I was
happy to see that they were not breaking deeper beneath the stiff wind slabs
created by Tuesday’s very strong wind and I hope that trend will continue
today. I expect that most of the
instabilities within the new snow will have settled out overnight. Still, I’m suspicious about all the recent
wind and snow and I’m sure there are a few pockets that you can pop out,
especially on the upper elevation, wind exposed, steep slopes. If they do break beneath Tuesday’s wind
slabs, they will be big avalanches—around 2-3 feet deep and they will likely
break above you. So be sure to practice
all your safe travel ritual like one-at-a-time and practice good slope cut techniques.
Also, the ridge top winds should blow from the southwest today around 10-15 mph with higher gusts and they will create some localized, fresh wind drifts along the wind exposed ridges. As always, you should avoid any steep slope with recent wind drifts.
Finally, if we get sun today, we will have more damp to wet sluffs on the steep southerly-facing slopes.
The avalanche danger is MODERATE on all slopes steeper than 35 degrees with pockets of CONSIDERABLE on the more extreme, upper elevation
Today should be a rest day with high clouds and ridge top winds from the southwest 10-15 mph and ridge top temperatures around 19 degrees. Down at 8,000’ the temperatures should rise to the mid 20’s. For the next several days, we have a large trough diving mostly south of us, which should wrap the moisture around it and bring our flow up from the south with clouds and occasional snow showers starting on Friday and continuing through about Wednesday.

There are several free automated avalanche beacon practice areas open, including one at Canyons, one on the by-pass road near Snowbird, one in the northwest corner of the lower lot at Solitude, and at the Nobletts parking area on the
