Today, the avalanche danger is MODERATE across all upper elevations for wind-drifted Snow. Here, you can find soft slabs of wind-blown snow that could be sensitive to the weight of riders. Be on the lookout and avoid areas with fresh drifts of wind-blown snow.

Special Announcements
To fulfill our mission, the UAC relies on our amazing backcountry community. Your support helps pay for the daily avalanche forecast, free awareness presentations across the state, and new tools like the new Avalanche and Observation Explorer. As the end of the year approaches, please consider donating to the UAC.
Weather and Snow
Under mostly clear skies, the mountain temperatures are cold and range from 5-10 °F. Winds continue to blow from the northwest but have slowed dramatically, and only a few anemometers report 5-10 mph wind speeds. Across the Ogden Skyline, the winds are a little stronger and blow from the northwest at 10-20 mph. In the past 24 hours, we've received a relatively even coat of fresh white paint. Storm totals ranged from 2 to 4.5 inches of new snow (0.20-0.30 water).
Today, we will have clearing skies as the storm exits and high-pressure returns. Winds should be on their best behavior and only blow 5-15 mph from the north. It will be a cold day as temperatures will only climb into the upper teens °F by this afternoon.
The recent storm has improved the riding and turning conditions dramatically, especially on aspects that still had dry cold snow underneath. On sunny slopes, there is a hard, slick, frozen crust in many spots where backcountry riders reported needing ski crampons in steep exposed terrain.
Recent Avalanches
In the backcountry, no new avalanches were reported in the Ogden area. However, ski area teams reported isolated six-inch deep wind slabs off upper elevation ridgelines.

Description
As you travel across upper elevation ridgelines be on the lookout and avoid fresh drifts of wind-blown snow. These shallow, soft slabs of wind-drifted snow will likely be less than a foot deep, but they could be reactive today, especially on slopes where the old snow surface is weak and faceted (northerly-facing terrain).
Additional Information
What happened to the Persistent Weak Layer (PWL) problem? The PWL problem first appeared in the December 1 forecast and was removed from the forecast on Wednesday, December 20. On Thursday, December 21, forecasters Nikki Champion and Greg Gagne talked about the PWL problem over a Zoom call and their 5-minute discussion. Be sure to watch the video.
