Forecast for the Uintas Area Mountains

Craig Gordon
Issued by Craig Gordon for
Wednesday, November 14, 2012

On steep, upper elevation, north facing slopes above treeline you'll find a MODERATE avalanche danger and human triggered avalanches breaking to the ground are possible. Caution should be exercised on steep slopes in this terrain. Remember - it's early season - consequences are often severe for someone getting caught and dragged through rocks and downfall in the thin coverage. A LOW avalanche danger exists on South facing terrain that was bare prior to the early November storm.

The game is on - carry a beacon, shovel, probe, first aid gear and travel one at a time through steeper terrain.

Special Announcements

Welcome to the new look of the avalanche advisory. This past summer we had a series of meetings and negotiated a unified look-and-feel of the avalanche advisories and web pages for other avalanche centers in this region including Jackson, Wyoming, Sun Valley and the Sierra Avalanche Center. Eventually all these sites should look very similar and the plan is for Colorado to join the look next winter. In another week or two we expect to have two viewing choices for the advisory page--this basic view and the "advanced" view most are familiar with from last season with colored danger ratings in the aspect-elevation diagram.

We are still in the process of transferring the pages and content from our old website to the new site, so be patient. We are also tweaking the look and design so you may notice some changes. When everything is finished, it should all be pretty cool.

In addition, we've expanded our Uinta weather station network adding two more sites near Currant Creek Peak. We're still working on some communication logistics, but expect the data to be flowing through cyberspace by weeks end. I'll provide links on the advisory page when we're up and running.

Weather and Snow

Wow... what a great start to the season. The big November storm pummeled the state like a crossfire hurricane, laying down over 2' of new snow along the upper elevation terrain throughout the range. And while it looks like winter is in full swing reality suggests the Uinta's are white from far, but far from white. Yup, it's still super thin and rocky. Riding conditions are best - and safest - on low angle north facing grassy slopes at mid and upper elevations. Previous to this storm, all southeast through south through westerly facing slopes were bare ground. Ted's been out and about and submitted this excellent observation

Currently, west and southwest winds are blowing 20-30 mph along the ridges and temperatures are in the low to mid 30's.

Both Mirror Lake Highway and Wolf Creek Pass remain open, but don't let the easy access to nearby terrain lull you into a false sense of security. Be prepared for your own self rescue. Wear and know how to use a beacon, shovel, and probe.

Recent Avalanches

On Sunday, a couple of very experienced backcountry skiers unintentionally triggered a 1'-2' deep x 100' wide slab on a steep shady slope near Murdock Peak along Mirror Lake Highway. The avalanche broke on old October snow.

Avalanche Problem #1
Persistent Weak Layer
Type

Likelihood
Size
Description

Winds ramped up overnight and there may be a few fresh wind drifts sensitive to the additional weight of a rider. These are limited to upper elevation north facing slopes and are easy to detect by there rounded, chalky appearance.

Avalanche Problem #3
Loose Dry Snow
Type

Likelihood
Size
Description

Late October snow never melted off the high north facing slopes. As a matter of fact it has grown weak and sugary overtime and now a cohesive slab rests above this persistent weak layer. While the storm snow has settled and is not quite as sensitive as just a few days ago, given the suspect snow structure human triggered slides breaking into old snow are possible. I'd be suspicious of steep, rocky, upper elevation north facing terrain where triggering a slide could result in a season ending injury.

Additional Information

Today we can expect mostly cloudy skies, temperatures warming into the mid and upper 30's, and southwest winds blowing into the 20's and 30's along the high ridges. Not much going on in the weather department for the next couple of days. Perhaps a few flurries late Friday and a better shot of snow Sunday into Monday.
