Ogden Avalanche Advisory

Forecaster: Bruce Tremper


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

I've issued a Special Avalanche Bulletin this morning for areas south of I-80. In areas with over a foot of new snow combined with wind, there is a CONSIDERABLEavalanche danger.

Danger Rose Tutorial

The backcountry avalanche danger is MODERATE on any slope approaching 35 degrees or steeper with new snow depths over a foot deep on any slope with recent wind drifts. Some avalanches on mid elevation north through east facing slopes may step down into deeper weak layers.


Yep, it’s official, at least in the Salt Lake area mountains, this is a call-in-sick-for-work day. Storm totals for Alta are 17 inches this morning with storm totals expected to reach 2 feet for favored areas in the Salt Lake area mountain by mid day when the snow should turn more showery. However north of Salt Lake, much less snow fell. Almost no snow fell in the Logan area mountains, 3 inches on Ben Lomond Peak, 9 inches in the Uintas, the Provo area mountains and central Utah. Ridge top winds were light overnight but they have picked up this morning and are blowing much harder from the northwest, 15, gusting to 30 on most ridgelines and 40, gusting to 60 on the highest peaks. Winds seem much more calm down off the ridges.


We did not hear about any human triggered avalanches from the backcountry yesterday with the exception of a few, shallow wind slabs from the very strong southeasterly winds. With all the new snow overnight and the increased wind this morning, there have been several natural avalanches recorded by the automatic infrasonic sensors above the road in Little Cottonwood Canyon.


      Over the next 12 hours.

We have no information from Snowbasin or Powder Mountain ski areas this morning, but the Ben Lomond weather station recorded 3 inches of snow overnight. The new snow should be fairly manageable with the exception of slopes where the wind has created deeper wind drifts.


      Over the next 24 hours.

Our old friend, the buried surface hoar layer, will be partially reactivated with the weight of this new snow, so some of the new snow avalanches could easily step down another couple feet deep to these deeper weak layers. You’ll find these mostly at mid elevation, north through east facing slopes. There are also some weak crust-facet sandwiches on the south facing slopes as well.


The storm is wrapping around and bringing in moist, unstable air from the northwest. We should continue to pile up perhaps another 8 inches of new snow in places favored by northwest flow such as the Salt Lake area mountains. Ridge top winds will continue moderate and gusty at times from the northwest 10-20 with gusts to 30. Snow should taper off to showers after noon. Ridge top temperatures will remain near the mid teens.


Please contact Snowbasin ski patrol (801620-1000/1017) if you trigger a large avalanche in the backcountry, especially if you are adjacent to a ski area, 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.
