Under mostly cloudy skies,
temperatures remained warm in the mountains, rarely dropping below 20
degrees. By around , the winds, already averaging in the teens and
twenties, bumped up a notch or two into the 20’s and 30’s out of the west and southwest,
with some gusts around 50. The

the central Wasatch, as Ethan Greene puts it, the avalanche conditions can best
be described as pockety in nature. The instabilities are far from widespread,
but it’s difficult to define a legitimate pattern. Not only are separate slopes quite
individual, areas along the same slope are as well – on a traverse, you can go
from an area of relative strength to a weak spot over a matter of feet. While it does look like most of the recent
activity has been on steep, upper elevation north facing slopes along the upper
Cottonwood Ridgeline, I feel certain that other booby-traps exist with similar
terrain characteristics elsewhere along the range. The trick will be to gauge
each area individually, keep your slope angles down, and follow safe travel
protocol. One of our observers went to
investigate the slide that was triggered near
Once the flood gates open, we may be in for some interesting activity. We have some pretty weak surface snow on the shady aspects, patched together with a variety of hard wind and sun crusts. The few inches for tonight may make things tricky for tomorrow, but the Thursday night storm will likely make for a good cycle, with a high likelihood of any activity stepping down to weak layering in the mid-pack.
The danger of human triggered avalanches remains MODERATE on mid and upper elevation northwest through east facing slopes steeper than about 35 degrees. Human triggered avalanches are possible. It will still be possible for any avalanche to step down into deeper, faceted snow.
areas have had a thin snowpack most of the winter, and the sugary weak snow is
more common than in the Cottonwood Canyons.
The danger of human triggered avalanches is more widespread in the
Same as above.
Today we’ll see mostly cloudy skies and some light showers during the day. Ridgetop winds will be out of the west to southwest in the 30’s and possibly into the 40’s by late afternoon. 8000’ highs will be in the mid to upper 30’s with 10,000’ temperatures in the mid-twenties. Tonight’s storm will be on a strong southwest flow, producing 4-7” at favored locations, with light snow again tomorrow. At this time, Thursday night’s storm is looking pretty good.
Wasatch Powderbird Guides will probably not be flying today, but if they do get
out, will be in the Silver, Day’s,
