Forecast for the Uintas Area Mountains

Craig Gordon
Issued by Craig Gordon on
Wednesday morning, December 24, 2025

Heads up... a warm, wet, weird weather system conspires to create unusual avalanche conditions. Expect a rising avalanche danger overnight as the Christmas storm evolves-

For today, at and above treeline, CONSIDERABLE avalanche danger exists. Human triggered avalanches, breaking up to four feet deep are LIKELY, especially on steep, rocky, slopes where a hard, dense slab sits above multiple persistent weak layers.

Elsewhere, slopes with enough coverage to ride offer pockets of MODERATE avalanche danger and it's POSSIBLE to trigger a stiff wind-drift on the leeward side of ridges, or around terrain features like gully walls, chutes, and cut banks.

Weather and Snow

Nowcast - A short-lived break in cloudiness offers a slot of clear skies at o'dark thirty, but winds blowing from the south continue working through their night shift, cranking 30-50 mph near the high peaks. The warm before the storm delivers trailhead temperatures registering in the upper 30's °F with ridgeline elevations clocking in right around freezing.

Forecast - Look for thickening clouds, high temperatures climbing into the mid 40's °F, and storminess developing late in the day. Winds blow from the south, blasting the ridges with gusts in the 40's and 50's while the high peaks get nuked with 70 mph gusts. A slug of moisture slides into the region mid afternoon with high elevation rain, turning to snow late tonight.

Futurecast - Two waves of storminess are in the queue. The first impulse arrives later today, delivering rain up to nearly 10,000'... dang. Cooler air then slides into the region overnight and we might squeak out six inches of snow. A colder storm swings through northern Utah Friday night into Saturday and that should give us a better shot of snow. I'm still thinking storm totals in the 12-18 inch ballpark with 1.25 to 1.5 inches of water for Saturday mornings ride.

Our good friends and long time partners at Salt Lakes National Weather Service have issued a Winter Weather Advisory for the western Uinta zone.

Travel Conditions - What a difference the weekend storm made across the range! Sure it's dry and thin at the trailheads, but don't let your hearts be troubled. Gain some elevation and it's a different world with average snow depths in the 24 inch range and deeper totals the closer you head towards the North Slope. Riding conditions have significantly improved, and although thin, the pack is supportable in many places and travel off-trail is now a thing. Vehicle access to Mirror Lake Highway (HW150) and the Corridor has been shut down, while SR-35 (Wolf Creek Pass) remains open.

Upper elevation meadows are the ticket right now. Andy stomped around on Sunday, crunching the numbers along the way and his math was simple ... mellow slope angles + grassy terrain underneath = all four A-arms making it back to the rigs in one piece.

Recent Avalanches

Yesterday, Trevor and I took a deeper dive into the avalanche he remotely triggered on a steep, rocky slope earlier in the week.

Avalanche Problem #1
Persistent Weak Layer
Type
Location
Likelihood
Size
Description

A northeast facing slope at 10,500' in the Gold Hill area, where a persistent slab avalanche released naturally one to two feet deep, failing on weak snow near the ground, and wrapping around terrain features a couple of hundred feet wide toward a nearby ridge. Our main man Ted Scroggin was on case and more deets on this Gold Hill slide from Ted's awesome write-up are found, here.

Yesterday, I found the snowpack stiff, somewhat shrink-wrapped, and not nearly as reactive as earlier in the week. But man, I'm not ready to hang my hat (as if I owned one :) on the snowpack structure 'cause it's an untrustworthy gong show. Remember, early season snow turned persistent weak layer homesteads beneath a strong, dense, cohesive slab that developed from several storms worth of snow, coupled with strong winds. But it's not a one-size-fits-all kinda snowpack and the biggest clue to our quirky snowpacks personality are recently triggered avalanches on mid and upper elevation, polar slopes, breaking 1-3 feet deep, failing on old snow near the ground. Steep, rocky slopes with a thin, shallow snowpack are at the center of the bullseye terrain and need to be avoided.

Here's the conundrum... in wind-sheltered, mid-elevation terrain, the slab is softer and not quite as reactive, but let's not take our eyes off the prize... it's still a strong snow over weak snow setup and that structure is always a big, red flag.

Remember, we can trigger persistent slab avalanches remotely or from a distance. Once initiated, today's avalanches may break deeper and wider than we expect, taking us for a body-bruising ride, raking us through rocks, trees, stumps, or deadfall.

Red flags are keeping us on our toes on the north half of the compass and can't be ignored. All the snowpros I knows are observing no shortage of audible collapses and cracks shooting out hundreds of feet around them.

Avalanche Problem #2
Wind Drifted Snow
Type
Location
Likelihood
Size
Description

A steep, thin, and rocky ridge on a north facing slope around 10,300' that has a dense wind-drift in the starting zone.

I suspect most of our snow is either welded or pressed in place and I bet you'd have to go out of your way to trigger a piece of wind drifted snow. However, the Uinta's are a big zone and the terrain can channel snow into unusual places. That said, I'm gonna continue to look for and avoid dense, textured, rounded pillows of snow, especially if they sound hollow like a drum. I'm also steering clear of cross-loaded terrain features like chutes, gully walls, and cut banks.

Note to self... stiff, hard slabs can feel supportable and solid under our rig, allowing us to get further out onto the slope before we kick the legs out from underneath. Lose the wind and you lose the problem.

Additional Information

This fleet can't be beat! Huge thanks to Ski-Doo in partnership with Karl Malone's Plaza Cycle, for arranging our sled, loaner program. This vital state-wide partnership gets sleds into the hands of UAC forecasters, allowing us to see more terrain, gather more snowpack information, and issue more accurate avalanche forecasts. Ultimately, this program helps us save lives!
