Uintas Avalanche Advisory

Forecaster: Craig Gordon

SPECIAL ANNOUNCEMENT

A Special Avalanche Advisory has been issued for the mountains of Northern and Central Utah. Dangerous avalanche conditions exist. Strong winds are blowing the snow into drifts that can be easily triggered by backcountry travelers from a distance. Backcountry travel in steep avalanche terrain is not recommended.


BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

At and above treeline dangerous avalanche conditions exist. In the wind zone a Level 4 (HIGH) avalanche danger will be found today and human triggered avalanches breaking to weak snow near the ground are likely.

At treeline and on any steep, mid elevation slope, especially those facing the north half of the compass, a Level 3 (CONSIDERABLE) avalanche danger exists.

Mid and low elevation slopes facing the south half of the compass offer Level 1 (LOW) avalanche danger.


CURRENT CONDITIONS

Just what we needed… hurricane force winds. A storm system just to the north of our region is producing west and northwest winds averaging 50 mph with gusts in the upper 70’s. Winds are ripping into the 30’s even at lower elevations and valley bottoms. Looks like just an inch of snow has fallen and temperatures dropped into the mid teens overnight. The Uinta’s didn’t escape Wednesday’s rain event and a thin crust is found on all aspects and at all elevations. Riding and turning conditions have gone from bad to worse and last night’s wind event turned much of our upper elevation terrain into a moonscape.


RECENT ACTIVITY

Two slides were reported yesterday near Elizabeth Pass, both on east facing slopes and both broke to the dirt. Fortunately no one was caught.

Ted and Joe stomped around Bald Mountain Pass yesterday. Click here to view their observations.

THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Winds are raging not only along the ridges, but also getting well down into terrain that is normally protected from the wind. Unfortunately, this is exactly where some of the weakest snow exists and now there’s a stout slab resting on top of this house of cards. (Click here to view a video explaining the sketchy setup).

Avalanche conditions are quite tricky right now and terrain that we normally ride in during times of elevated avalanche danger are prime suspects. It’s not just the steep slopes we need to avoid today. Even if you’re traveling on low angle terrain be aware you can trigger avalanches from a distance. Today’s avalanches will break deeper and wider than you might expect and will pack a powerful punch.


MOUNTAIN WEATHER

This morning we can expect strong west and northwest winds gusting into the 40’s at lower elevations and into the 60’s and 70’s along the ridges. A passing snow shower will add an additional inch or so before high pressure builds and skies clear. Temperatures rise into the low 20’s and bottom out into the teens overnight. Clear skies and warming temperatures are on tap for the remainder of the weekend into early next week… there are no big storms in sight.
