Forecast for the Uintas Area Mountains

Craig Gordon
Issued by Craig Gordon on
Saturday morning, December 20, 2014

In the wind zone at and above treeline a MODERATE avalanche danger exists and human triggered avalanches are possible on steep, wind drifted slopes facing the north half of the compass. Remember- triggering even a small slide will expose stumps and rocks, instantly ruing your day and quite possibly your season.

All other terrain offers a LOW avalanche danger.

Avalanche Watch

THIS AVALANCHE WATCH IS FOR THE WASATCH...BEAR RIVER AND WESTERN UINTA MOUNTAIN RANGES AND FOR THE NORTHWESTERN PORTIONS OF THE WASATCH PLATEAU. A WARM WINTER STORM WITH HEAVY SNOW AND STRONG WINDS WILL RAPIDLY INCREASE THE AVALANCHE DANGER BEGINNING TONIGHT AND CONTINUING THROUGH MONDAY.

Special Announcements

We just released an exciting, new avy safety video designed specifically for snowmobilers - Knowledge is Powder. https://vimeo.com/113677686

NEW THIS YEAR: You can now receive advisories by email for each region in the state. Go here for details.

Weather and Snow

Clouds streamed into the region overnight, ahead of an active weather pattern slated for the next couple of days. Currently, temperatures are in the low to mid 20's. Southwest winds bumped into the 20's and 30's overnight, but have calmed down and are currently blowing 10-20 mph. While average snow depths throughout the range remain relatively shallow, surprisingly good riding and turning conditions are found on a mostly supportable base, especially on low angle meadows and rock free slopes.

Pole dancing in the western Uinta's. Huge thanks to the Park City Powder Cats for their help yesterday installing the Windy Peak weather station. We are working through some communications issues, but hope to have everything on line shortly.

Recent Avalanches

The surface snow is very weak. While manageable in depth and size, it doesn't take much to initiate new snow sluffs on steep slopes across the range.

Description

There's plenty of light density snow to blow around and winds are expected to increase later today... it'll be a day of rising avalanche danger. As the storm develops and winds begin to ramp up, I suspect fresh drifts will break wider and deeper than you might expect. While mostly manageable this morning, by days end these fresh slabs will be packing a punch and you'll want to avoid any steep slope with recent deposits of wind drifted snow.

Whoomphing sounds or shooting cracks in front of your skis, board, or sled are huge clues to unstable snow.

Additional Information

Today we can expect mostly cloudy skies with scattered snow showers. Temperatures climb into the upper 20's and low 30's. Tonight the main event rolls into the region and southwest winds begin cranking into the 50's and 60's along the high ridges. Snow develops and temperatures will be relatively warm and in the upper 20's. Sunday will be warm and windy with dense, heavy snow stacking up. Snow, with rain below about 8000 feet and strong winds continue Sunday night. A cold front lowers snow levels early Monday, but the snow turns showery and starts to taper off. Storm totals in the 12"-18" are a good bet by the time this system winds down.
