In sintesi

HEADS UP... strong winds are changing the landscape, creating dangerous avalanche conditions and human triggered avalanches are likely.

Near and above treeline today on slopes facing west through north through east, the avalanche danger is CONSIDERABLE and HUMAN TRIGGERED AVALANCHES ARE LIKELY. Today's avalanches are nothing to toy with as they are unmanageably large, breaking deep and wide, taking out the entire seasons snowpack.

You'll find MODERATE avalanche danger at lower elevations and HUMAN TRIGGERED AVALANCHES ARE POSSIBLE on steep, wind drifted slopes, especially those facing the north half of the compass.

Here's your exit strategy- the Uinta's offer plenty of great, low angle terrain options. Simply stick with slopes less than 30 degrees in steepness and make sure there's no steep terrain above or adjacent to where you're riding. You can have a blast meadow skipping or carving deep trenches in wide open meadows... done and done.

    The snowpack is slowly adjusting to last weeks storms and now a new round of snow and wind will overload our structurally challenged snowpack. The bottomline... most slopes wait for a trigger like us to roll along and knock the legs out from underneath.

    Today's storm will be a one-two punch on the chin of our snowpack. And as snow begins falling and winds continue cranking they'll work in concert together to create additional weight and stress on weak layers of snow buried in the mid portion of our snowpack. Let's face it, the Uinta pack is structurally challenged with strong snow resting on top of weak snow. What this means for us is that any slide we trigger is gonna break deep and wide. Now, I wouldn't build my house on a foundation like that and I'm certainly not gonna bet my life on it... so avalanche avoidance is the big ticket. Since we know this setup is found on mid and upper elevation slopes facing the north half of the compass, we can simply avoid where this avalanche dragon lives and still have a blast riding low angle terrain with no steep slopes above of adjacent to us.

    Remember- in the past few days there have been multiple slides triggered, a few close calls, and one tragic fatality nearby, with a snowpack structure similar to ours. The writing is on the wall and Mother Nature is screaming the biggest clue to unstable snow... and that's AVALANCHES!

    A 24 hour data dump from Lofty Lake Peak clearly shows a bump in the winds beginning in earnest right around dinnertime last night.

    Hurricane force winds are rapidly forming dense, cohesive slabs on leeward slopes at mid and upper elevations and probably getting into lower elevation terrain as well. Problem is... they're hard to detect, but once triggered, they may break into deeper buried weak layers as the crash onto the slope below. Here's the good news... you can simply avoid this avalanche dragon by avoiding steep, wind drifted slopes, especially if the snow looks fat and rounded or feels and sounds hollow like a drum.

    In mid and upper elevations, this is the type of avalanche you can trigger today.

Special Announcement

It is with great sadness I report an avalanche accident which occurred last Saturday, along the Park City ridgeline, on Squaretop Peak. Our report is found here.

Our collective thoughts, prayers, and energy go out to friends and family of 57 year old, Kurt Damschroder, of Park City, Utah who was tragically killed in Saturday's accident.

Recent Activity

A great image caught by Eric Fields illustrates a human triggered windslab from Monday in Upper Moffit Basin. Breaking 2'-4' deep x 150' wide and failing on surface hoar, this slide ran on a hard, slick crust. More info here.

Snow and Weather

Nowcast-

The big headline news are the winds, and they're nuking in the 40's and 50's along the high ridges. With mostly cloudy skies blanketing the mountains, temperatures are mild, registering in the upper 20's and low 30's. No new snow since last weeks storms but they were good to the eastern front, stacking up several feet of snow, dramatically improving riding and turning conditions.

Forecast-

A cold front is on our doorstep and it slides through the area late this morning. Snow develops after sunrise and should be heavy at times, continuing through the afternoon. West and southwest winds crank into the 40's and 50's, with gusts in the 70's along the high peaks. Snow winds down tonight and I think storm totals should stack up in the 6"-10" range.

Futurecast-

A brief clearing with colder temperatures is on tap for Thursday with another weak storm slated for Friday.
