For the first time since December 14th, we have lowered the overall danger rating to MODERATE.  This means that “dangerous avalanche conditions on some terrain features. Evaluate the snow and terrain carefully and use good travel habits.”  You could trigger avalanches today on any steep slope with recent wind drifts and you could also still trigger some very isolated areas of deep, dangerous avalanches, most likely from shallow, steep rocky areas with a fresh load of wind drifted snow.

What a difference a day makes, as they say.  A major snow travesty occurred yesterday.  At least on the north through west facing slopes, a stout layer of rime ruined all our nice powder we enjoyed so much on Saturday.  The warm front and stratus clouds smashed into the upper half of the mountains with super-cooled water that froze on contact whatever it touched, creating some very loud powder.  You could hear people coming from a half mile away and little pieces of snow skittered down the slick zipper crust.  The good news is that the rime was not bad everywhere.  It tends to coat the upwind sides of ridges and the downwind sides escaped with a much thinner coat.  It’s kind of hit-or-miss.   If you’re from Washington, you will feel right at home, but for the average, spoiled Utah’n, it elicits the same response as spraying a cat with a garden hose. This morning, very light snow showers are falling.  Ridge top winds blew hard again last night from the northwest, blowing 30-40 with higher gusts.  Ridge top temperatures have dropped to around 20 degrees.

Once again, we did not hear about anybody triggering avalanches yesterday, with the exception of some small, cornice-triggered wind slabs along the upper elevation ridges in the Salt Lake area mountains.  The Uinta Mountains, however, remain active with another couple, large, natural avalanches reported yesterday morning, breaking to the ground, probably from the strong winds the night before.

It will feel like Groundhog Day—a repeat of yesterday but a little colder, with stratus clouds, strong northwest winds, light snow showers and ridge top temperatures in the mid 20’s.  A high pressure ridge will slowly build in over the next several days with progressively warmer temperatures at upper elevation rising into the 40’s along the ridge tops by the weekend.  We don’t see any significant snow for at least 10 days.

The Utah Avalanche Center is hosting a Level 2 avalanche class in February which is now open for registration by going to the Black Diamond retail store.  More information is HERE.

Beacon training parks are up and running!  On the Park City side, there is one at the top of Canyon’s gondola, in Little Cottonwood one is near the Snowbird parking structure on the bypass road, and in Big Cottonwood a training  park is at the west end of Solitude's lower parking lot.
