Terrain to avoid- Steep, rocky, upper elevation slopes where human triggered avalanches breaking near the ground are still possible.

A MODERATE avalanche danger exists and human triggered avalanches within the new storm snow are possible on steep, wind drifted at all elevations.

LOW avalanche danger is found in wind sheltered terrain.

Special Announcements

We still have a few slots open. Please join us on Thursday evening, 1/24 and Saturday, 1/26 for a day of learning avalanche and advanced riding skills with Craig & Trent from the Utah Avalanche Center and Dan Gardiner and the Boondockers crew. Details and sign up here

Weather and Snow

Thursday's storm was good to the eastern front and just about a foot of Utah's finest blower powder fell evenly across the range. A very cold northwesterly flow is in place giving us mostly cloudy skies and brutally cold temperatures this morning. With temperatures near -10 degrees... you're gonna wish you plugged in the block heater overnight. Fortunately, northwest winds are light, in the 5-10 mph range, but that still gives us wind chill near -20 degrees. If you can get over the cold, the riding and turning conditions in wind sheltered terrain are about as good as it gets.

Recent observations can be found here.

Recent Avalanches

Ted found this fresh slide on Gold Hill. Sluffing and sensitive, yet shallow wind drifts were the flavor of the day.

Description

Recent west and northwest winds helped whip up a fresh batch of wind drifts and yesterday these were sensitive to the additional weight of a rider. Lots of cracking and collapsing was reported, especially at mid and lower elevations where Tuesday's rime crust is supporting the weight of all the new snow. Today's avalanche danger is mostly manageable and shallow soft slabs will predictably break at or below your skis, board, or sled. One wild card is the more pronounced avalanche danger at mid and lower elevations where the snowpack is slightly weaker and may therefore be a bit more reactive to your additional weight. Don't let your guard down on steep slopes near the trailheads as you're headed to the big, upper elevation terrain .

Tuesday's rime crust is capping a layer of weak sugary near surface facets. And yes, that's a thin layer of surface hoar on top of the crust... yikes!

With a foot of new snow on top, there's plenty of cracking and collapsing or whoomphing sounds. Thanks JG for the great pics!

Description

You'd have to go out of your way to trigger an avalanche that breaks into old snow near ground today. However, if your travels take you into steep, complex terrain today, stop for a moment and carefully assess the snowpack and think about the consequences of triggering an avalanche.

Additional Information

A cold, moist northerly flow is over the region and man, it's gonna be a finger numbing day with highs only reaching into the single digits. Mostly cloudy skies with northwest winds blowing 5-10 mph along the ridges will add more of a bite to the day.High pressure begins building late Sunday leading to a gradual warming next week.
