Forecast for the Uintas Area Mountains

Mark Staples
Issued by Mark Staples on
Sunday morning, December 24, 2023
Yesterday's snowfall put a beautiful coat of white paint on the Uintas. Above treeline, the avalanche danger is MODERATE on wind loaded slopes where slabs of wind drifted snow are the main concern. All other slopes have a LOW danger.

The new snow begs us to make some gentle turns in rock free meadows. It's certainly worth getting out, but tread lightly as the snowpack is still thin and barely covering rocks, logs, and stumps.

Weather and Snow
Yesterday's much needed storm dropped 2-5 inches of snow (0.1-0.4 inches of water) across the Uintas in the morning. Flurries continued through the day. North winds in the afternoon brought very cold air and temperatures began plummeting. This morning, temperatures at upper elevations are hovering around 0 degrees F and in the low teens F at trailheads. Winds are fairly light for the Uintas, averaging 10-15 mph gusting to 26 from the north and northwest.
Today will be mostly sunny and cold with temperatures at upper elevations struggling to get into the low teens F. Winds from the north will blow 10-15 mph which will be especially noticeable with such cold temperatures.
Moving into this week, the weather will generally be cold and dry as winds from the north continue for a few days. By mid week, a ridge of high pressure moves overhead with some warmer temperatures.
The new snow is generally resting on an ice crust on south-facing slopes. The snow surface on northerly and easterly facing slopes became somewhat weak and faceted last week, but that creates a soft layer underneath yesterday's snow. Dense snow from the first weekend of December found in the middle of the snowpack provides some supportability. Under that layer is old November snow which is weak and faceted, but shouldn't be stressed by the recent snow.
Generally there's about two feet of snow in the Uintas although you can find a few places at upper elevations with closer to three feet.

Recent Avalanches
No avalanches were reported in the Uintas, but yesterday some shallow slabs of wind drifted snow were triggered by backcountry travelers and ski patrols in the Wasatch Range.
Trip reports and the latest observations are found HERE.

Description
Wind from the north and north west formed some shallow slabs of wind drifted snow. Most are likely 6 inches deep but I bet a few could be up to a foot deep. Look for these fresh wind slabs mainly at upper elevations on the downwind side of ridges or other terrain features.
On southerly aspects, these wind slabs likely rest on an ice crust and could begin to stabilize quickly. Wind slabs on slopes facing other directions are likely resting on some faceted snow and may remain touchy for a number of days.
