Ogden Avalanche Advisory

Forecaster: Brett Kobernik


Dangerous avalanche conditions are occuring or are imminent. Backcountry travel in avalanche terrain is not recommended.

The avalanche warning continues for all the mountains of northern Utah. Deadly human triggered avalanches continue to be very likely on steeper slopes. Avalanches can be triggered from a distance so stay out from underneath steep slopes as well. People without expert level backcountry avalanche skills are urged to stay out of the backcountry.


Danger by aspect and elevation on slopes approaching 35° or steeper.

The avalanche danger is HIGH. Human triggered avalanches on mid and upper elevation slopes that face west through north through east are very likely still. Avalanches can be triggered from a distance so stay out from underneath these slopes as well. Low angle terrain continues to be the choice of the well versed backcountry traveler.


Under light snow, temperatures are in the low teens with a few stations in the low 20s with light northwest winds. Snowbasin has picked up 6 inches of new snow in the last 24 hours. Riding conditions are good and trailbreaking manageable. The slab is settling into a more dense unit making sled travel possible in many more areas now.


Drew's field day on Cutler was not showing immediate signs of instability. DETAILSThe signs he and his partner did note were the recent avalanches from the natural cycle and a poor snowpack structure. With the slab gaining lots of strength but the weak layer still quite loose, we move into a period where triggering something is still possible but not as likely, but consequences are lethal. This is the worst situation to forecast for. It is hard for people to understand why the danger is high when they are not seeing activity.

Keep in mind that this weak layer is something many us have never seen or dealt with and it is likely to produce avalanches for a while. Thinner overall snowpack areas may be more active.


      Over the next 24 hours.

Avalanches breaking into weak snow from earlier in the season remains your number one concern today. No one who has an intimate knowledge of snow is getting onto steep slopes. Collapsing is becoming less frequent and things are not as sensitive as a couple days back. We will move into a lower probability / high consequence situation - the worst to forecast for. The take home is you can’t trust a faceted persistent weak layer ESPECIALLY one like many of us have never seen or dealt with. Let it be for a while.


Snowfall in the mountains should trickle to a stop this morning and skies may break a bit as the day goes on. High temperatures should get into the upper teens along the ridges and mid 20s at 8000 feet. North winds should remain fairly light. We could see light snow showers at times Wednesday and Thursday with another little refresher storm on Friday.
