Forecast for the Uintas Area Mountains

Craig Gordon
Issued by Craig Gordon for
Wednesday, March 8, 2023
And just like that... avalanche danger is quite straight-forward-
In a sea of green, pockets of MODERATE avalanche danger exist on steep, leeward slopes in the wind zone at and above treeline. While not widespread, human triggered avalanches are POSSIBLE, especially in wind drifted terrain facing the north half of the compass, and particularly on slopes with an easterly component to its aspect.
If you're looking for LOW avalanche danger you came to the right place. Simply steer your snow riding vehicle toward mid and low elevation terrain, especially slopes facing the south half of the compass where human triggered avalanches are UNLIKELY.

Weather and Snow
Nowcast- Southwest winds blow 20-30 mph along the high ridges, helping to usher in a band of thin clouds, which drift over the region early this morning. Temperatures are crisp, hovering in the teens across the board. On a go-anywhere base and with over four feet of storm snow stacking up in the past week, riding and turning conditions are all-time.
Forecast- Look for mostly sunny skies this morning with high temperatures climbing into the upper 20's The buzz-kill are southwest winds, ramping into the 40's and 50's, along with thickening clouds late in the day. A quick hitter delivers cold air and an intense shot of thunder snow right around sunset. Accumulations in the 3"-6" range seems about right.
Futurecast- A break on Thursday delivers sunny skies and temperatures rising into the upper 20's. It's a short-lived respite as a pattern shift slated for Friday brings in a warm, moist, atmospheric river to round out the work week.
Our good friends at the NWS in the City of Salt, lay out the timeline for today's late afternoon precip in the graphic above.
Micheal J found stable snow, straight-forward avy conditions and excellent riding in Lower Weber Canyon yesterday.

Description
Ominous overhanging cornice are a clue to both recent and older wind loading events. It'll also give us an idea where we might find a wind drift, reactive to our additional weight on steep, leeward slopes.
Most of our recent storm snow instabilities have settled out nicely in the past few days and are becoming comfortable in their own skin. And that makes sense, because snow is a lot like people and it gets cranky when it goes through a rapid change. However, we have several layers of storm snow that stacked up over the weekend and while they may be harder to initiate, once triggered, today's avalanches will pack a powerful punch. Steep wind drifted slopes facing the north half of the compass is bulls-eye terrain and today's avalanches will break deeper and wider than you might expect... so avoidance is the key to riding safely today. If your objective is tagging sustained steep terrain, consider the consequences of triggering a slide and have an exit strategy in place. Better yet, tweak small test slopes like road banks with characteristics similar to what you wanna ride and see how they're reacting to your additional weight, before blindly center punching a big, committing line.
Additional Information
Shake, rattle, and roll... looking towards Friday and into early next week... warm, wet, and windy! There's a potential for 30"of snow with 2.5" of H2O.
Weather stations-
And... rime events from January's atmospheric rivers severely crippled the Uinta weather station network. I'm working to get it back up and running, but a few stations are found HERE (click weather stations, and then on the Western Uinta tab)
