AVALANCHE WARNING!! Tap for info

Forecast for the Uintas Area Mountains

Game on... strong winds coupled with heavy snow begin to tip the scales and the avy danger is gonna get real-
Today, you'll find pockets of HIGH avalanche danger in the windzone at and above treeline. Both human triggered and natural avalanches are VERY LIKELY especially on steep, rocky, leeward slopes, and particularly in terrain facing the north half of the compass with an easterly component to its aspect.
Mid elevation northerly terrain is getting in on the act where you'll find CONSIDERABLE avalanche danger and human triggered avalanches are LIKELY on steep wind drifted terrain.
Low elevation shady slopes near our trailheads are pathetically weak and offer MODERATE avalanche danger. I suspect it won't take much additional weight in order to provoke early season snow near the ground and human triggered avalanches are POSSIBLE on steep slopes.
Looking for predictable avalanche danger? Well then, you came to the right place! Simply switch to terrain facing the south half of the compass where you'll find straightforward avy conditions and generally LOW avy hazard. But tread lightly... it's thin.

Avalanche Watch
What:
This Avalanche Watch is for rising avalanche danger, with very dangerous conditions continuing through the weekend and into next week.
Heavy snowfall and drifting by strong winds will elevate backcountry avalanche danger over the next several days. Very dangerous conditions and HIGH avalanche danger are expected to develop in many areas.
Where:
The Avalanche Watch continues for the western Uinta Mountains.
Impacts:
Very dangerous avalanche conditions are expected to develop on many slopes.
Avalanches can be triggered on slopes steeper than 30 degrees. They may also be triggered remotely (from a distance) or from below.
What to do:
Avoid traveling on or underneath steep terrain at mid and upper elevations in the backcountry.
Carry and know how to use avalanche rescue equipment.
Find safer riding conditions on slopes less than 30 degrees with no overhead hazard.
Weather and Snow
Nowcast- Skies clear briefly as the last flakes of snow get squeezed out of Friday's storm, leaving an evenly distributed 7" of snow with .65" H20 across the range. West and southwest winds partied through most of Friday, blowing 30-50 mph near the high peaks, but the ridgelines got complaints from neighboring peaks, put a lid on the festivities, called it a night around 11:00, and backed off into the mid 20's where they sit early this morning. Temperatures start their day in the mid teens.
Forecast- A decaying piece of Atmospheric River slides through the region today and that'll be good news for the Uinta's. Yeah, AR's tend to light up the eastern front, especially the Trial Lake area. Look for a good shot of snow to develop as the day progresses with a foot of snow a good bet by days end. West winds blowing 40-60 mph are gonna make for rugged travel, especially near the ridges. Temperatures warm into the low 30's and dip into the mid 20's overnight.
Futurecast- Look for a break in the action overnight into Sunday. One last gasp of storminess is left in the queue and should slide in late Sunday into Monday morning. Colder air helps deliver just a couple inches of low density snow.
Our good friends and longtime partners at Salt Lake's National Weather Service issued a Winter Storm Warning for a good portion of Northern Utah which of course, includes the western Uinta's.
Travel & Riding Conditions-
A little snow goes a long way and riding is just starting to come on. But remember... it's still lean and there's plenty of gear wrecking obstacles buried just below the snow surface. So tread lightly, or as local snow-pro and rider extraordinaire Andy Nassetta says... "keep 'er on all fours."
Recent Avalanches
Not a particularly large piece of snow triggered yesterday on a steep, wind drifted slope, but the writing is on the wall. I'm focusing on the characteristics of where the avalanche failed... on weak snow near the ground. With more snow and wind overnight, I think today's avalanches are gonna break deeper and wider and can easily roll us.
Local snow-pros and all around rock stars, Bo Torrey and Adam Davis, took some time off the concert scene to visit Wolf Creek Pass Thursday and have some great insight found here.
In addition, a close call occurred on Christmas Eve in the Logan area mountains, resulting in a complete burial. But fortunately, a quick thinking companion used his avalanche transceiver for the rescue, resulting in only minor injuries to the buried rider. The avalanche was 2 feet deep and 500 feet wide.

Description
Here's the wind up... and pitch... the snowpack is weak, it's tricky, and I suspect today's avalanches can be initiated from a distance. Here's where the rubber hits the road... any slide triggered is gonna break deeper and wider than you might expect and will easily ruin your day. Found mostly in mid and upper elevation terrain I wouldn't be too shocked to see a pocket or two down low.... like near our trailheads where the pack is an absolute weak, sugary mess. The writing is on the wall, the snowpack structure is a gong show and we're teetering on the edge. There's some unknowns right now, so let's not pull on the dogs tail to test our theories or take our eyes off the prize.

Description
24 hour data dump from Windy Peak (10, 062')
I suspect yesterday's strong wind whipped up dense drifts on the leeward side of upper elevation ridges and also penetrated mid and lower elevation terrain as well. There's plenty of good riding on wind sheltered slopes, so why not steer your snow vehicle towards wind sheltered terrain where you'll find soft, creamy snow and predictable avy hazard
