Danger Rose Tutorial

There is a MODERATE danger of human triggered avalanches on any slope approaching 35 degrees or steeper with recent deposits of wind drifted snow. These will look smooth and rounded with a hollow sound and will often crack or collapse under your weight. Out of the wind, watch for pockets of loose snow sluffing on steep slopes.


The higher elevations of the Wasatch Range got a mighty 3-5 inches yesterday and overnight, which was mostly graupel, that Styrofoam ball-type of snow. Winds blew hard from the west as the storm approached yesterday afternoon, but most of the precipitation came down after dark and after the winds dropped. Temperatures this morning have dropped to 25 degrees at 8,000' and into the mid teens along the ridge tops. Skies are mostly cloudy with light snow showers, which we expect to continue through most of the day.


There was no avalanche activity reported from yesterday, but most of the snow came down in the late afternoon and evening, so avalanche control crews are just getting out this morning.


      Over the next 24 hours.

The new snow came down with a moderate northwest winds, so Iexpect you will find the usual round of fresh with slabs along the upper elevation ridges, mostly on the east through south facing slopes, but they could be cross loaded into other terrain as well. I don't expect the new snow to weigh enough to overload some of the shallowly-buried weak layers of faceted snow and rime crusts. But in places where the wind has drifted the snow more than about a foot deep, I would expect there is enough weight to break down into the weak, faceted snow, which was on the snow surface before the weekend.


We will have a weak disturbance moving through from the northwest on Thursday, which should give us about 3 inches of new snow. Ridge top winds should remain reasonable at 5-10 mph from the south, switching to 15 mph from the northwest by mid day Thursday. Daytime highs on Thursday should be around 26 with the overnight low on Thursday night around 17. Skies should be mostly cloudy with light snow showers. On Friday we should have clearing skies with temperatures remaining in the mid teens to lower 20's.

The extended forecast calls for clear to partly cloudy skies through the weekend with another chance of snow on Monday. We still don't see any large snow storms on the way.


Evelyn Lees will update this forecast by 7:30 on Thursday morning.
