Ogden Avalanche Advisory

Forecaster: Brett Kobernik


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

An Avalanche Warning continues today. Many upper elevation slopes have been recently loaded with a substantial amount of snow from wind on Wednesday and snow Wednesday night. Naturally occurring avalanches are unlikely today but many slopes just need the weight of a person to trigger a dangerous avalanche. Avoid getting on steep slopes and stay out from underneath steep slopes as well.


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

Danger Rose Tutorial

The avalanche danger is CONSIDERABLE on all upper elevation steep slopes. BE CAREFUL - YOU COULD EASILY GO MOST OF THE DAY TODAY WITHOUT SEEING ANY OBVIOUS SIGNS OF INSTABILITY which could lead to a false sense of security. We expect to hear about human triggered avalanches today.


Temperatures are cold in the low teens to single digits and winds calmed down overnight and are light from the southwest. The Ogden mountains area picked up about 6 inches of new snow overnight.


Numerous sensitive soft slab avalanches were reported from the Ogden area that were 1 to 2 feet deep. There were a couple of naturals reported also from the windy conditions on Wednesday.


      Over the next 24 hours.

With a very complex weak layer pattern out there right now, I think it’s better to just try and keep it simple today. The recent wind and additional weight of last nights snow will make any one of our buried weak layers reactive to the weight of a person. Different aspects, elevations and locations will have different weak layers fail. It is best to let things settle and stick to lower angle slopes today.


      Over the next 24 hours.

There was at least one report from this morning of the new snow being inverted. This situation could point to new snow instabilities if it is widespread.


We should see only showery snow flurries today which probably won’t produce all that much accumulation until late this afternoon when the next wave moves through. We will have a quick period of snow this morning which could add a few inches. Winds should stay fairly light from the west and temperatures will get up to around 20 at 8000 feet and teens along the ridges. Another wave moves through late this afternoon which will produce another round of heavier snowfall. Temperatures will be cold and densities light. Another foot of snow is possible into Friday. Things stay unsettled into Saturday and we could see lingering snow showers until then. Things clear out and we’ll have rapidly rising temperatures on Sunday.


If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following teams to alert them to the slide and whether anyone is missing or not. Rescue teams can be exposed to significant hazard when responding to avalanches, and do not want to do so when unneeded. Thanks.
