Danger Rose Tutorial

The avalanche danger is Level 3 (CONSIDERABLE) on slopes approaching 35 degrees or steeper. It is most pronounced above around 8000 feet. Natural avalanches are not expected today but dangerous human triggered avalanches are likely. The large amount of recent snow and water demands some time to settle before getting onto steeper slopes.


Wow, what a storm system this has been. It seems like we’re actually seeing the tail end of it now. Overnight, another 6 inches of snow fell in the Ogden area mountains. The rain/snow line is hovering around 7000 feet. Storm totals for the week are about 36 inches with 6 inches of water. You can bet there’s a lot more in the upper elevations and especially in wind drifted terrain. Temperatures are mild again this morning in the mid 20s along the ridges and around freezing at the 8000 foot level. Winds are starting to shift from the southwest to the northwest and are fairly light along the ridges. Trail breaking on Wednesday was difficult no matter if you were on skis, snowshoes or a snowmobile. The snow was inverted causing submarining and I’d expect similar conditions today.


Another natural avalanche cycle occurred mid day Wednesday during moderate to heavy snowfall coupled with blustery southwest winds. Human triggered soft slabs up to 12" were reported from the Snowbasin area.


      Over the next 24 hours.

Give it a break out there today people. There’s nothing worse then investigating an avalanche fatality during the holidays. I can’t imagine what it would be like for Christmas to be a constant reminder of a loved one who was killed in an avalanche. Our snowpack is going to stabilize nicely but it needs a little time. The most active layer today will be within the newer snow with avalanches 10 to 15 inches deep. This is more then what I’d call manageable. Out of bounds resort skiers: Listen up. Exiting ski resort boundaries will put many of you in terrain with the biggest potential to avalanche today.


      Over the next 24 hours.

The astounding amount of new water weight is enough to break into deeper layers of our snowpack. Needless to say, an avalanche breaking into deep layers has the potential to be lethal.


No probability identified.
No size identified.
No trend identified.

You will want to avoid steep slopes especially gullies and terrain traps at the lower elevations where the snow is wet and saturated from rain. Small avalanches can pile up deep in these terrain traps.


We’ll see snow showers tapering off as the day goes on with a few additional inches possible. Temperatures will be quite mild and ridgetop winds should be fairly light from the northwest. We’ll have cloudy skies with VERY mild temperatures over the next couple of days that may influence the avalanche conditions. Stay tuned.



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.
