Points saillants

Today a MODERATE danger exists on all north, east, and south-facing upper elevation slopes where triggering a fresh slab of wind drifted snow is possible. Look for signs of wind drifted snow and use caution in steeper terrain.

As you lose elevation, you lose most of the problem. Low and mid-elevation slopes with no steep terrain above or adjacent to them have a LOW avalanche danger where generally safe riding conditions exist.

Continue to observe safe travel protocol. Practice with your rescue gear.

The main things to watch for today are soft slabs of wind drifted snow.

With a few new inches of snow, increased winds, and a change of wind direction in our future I would expect to see fresh slabs of wind drifted snow on upper elevation slopes. These new drifts of wind drifted will be primarily found on steep, north, east and south-facing terrain but you could expect to see isolated areas of wind drifts on all ends of the compass.

Avoid all slopes with signs of wind drifted snow, such as cracking, rounded and pillow-shaped deposits, and a hollow sound as you travel across it. CORNICE: We previously had several days of strong winds that created large and sensitive cornices along the exposed ridgelines. Today these cornices will continue to grow. Large cornices often collapse and break much further back than expected, so be sure to give them a wide berth when traveling along the exposed ridgelines.

Special Announcement

We are very sad to report an avalanche fatality from Saturday above Farmington Canyon. An 18-year-old male snowmobiler was caught, fully buried and killed. The final report is available HERE. Our deepest condolences go out to the friends, family, rescuers, and everyone affected by this tragic accident.

Recent Activity

Yesterday on Culter Ridge a shallow soft slab of wind drifted snow was triggered by a skier on a Northeast Aspect at 7,800'. This avalanche was 4 inches deep and ran 100' feet wide.

Snow and Weather

Snow lightly started falling early this morning. Total snowfall since yesterday morning is currently 2-4 inches.

Mountain temperatures remain warm and are hovering in the mid to upper 20s F this morning. Winds have increased overnight, at ridgetops they are currently averaging 15-25 mph with gusts 30-40 mph from the west-south-west near Ogden Peak.

Today a weather system will brush by the area and the mountains will pick up another 2-4 inches of snow in the morning, turning into showers by the afternoon. Skies will be overcast all day and temperatures will remain in the upper 20s to low 30s F. Winds will switch from west southwest to the west-northwest and average 20-30 mph, with gusts up to 50 mph at the highest of elevations.

A mixed bag of riding conditions exist, but one can still find some soft turns in the wind and sun-protected terrain.
