Ogden Avalanche Advisory

Forecaster: Bruce Tremper


Tragically, a snowmobiler from Evanston, Wyoming was killed yesterday in an avalanche he triggered in the Uinta Mountains in the Moffit Basin area. Our condolences go out to his family and friends. He was apparently a high-end rider and well-known in the community. It appears that they left their avalanche rescue gear in their vehicles because they did not plan to get onto any avalanche terrain but it appears that the victim triggered the avalanche from mid slope in Super Bowl, a popular snowmobile play area. We have a preliminary report and Craig Gordon will post a more complete report tonight after he returns from visiting the accident site today.

Danger Rose Tutorial

Today there is mostly a Level 1 (Low) danger of human triggered avalanches with pockets of Level 2 (Moderate) danger on any slope approaching 35 degrees or steeper with recent wind deposits and also on any steep slope getting soggy from sun warming.


Today should be another warm day in the mountains but with some increasing high clouds. Yesterday’s sun and warm temperatures put a sun crust on sun exposed slopes but there is still some soft, settled powder on the shady aspects.


In the Wasatch Range, where the snowpack is much more stable, there was no reports of human triggered avalanche activity from yesterday. People have sent us photos of glide cracks opening up in Mineral fork but they have not released yet.


      Over the next 24 hours.

The snowpack appears to be mostly stable but there are still places where you can probably trigger an avalanche. The most likely paces would be wind slabs especially at upper elevations along the ridges and especially in thin snowpack areas. These could either be fresh wind slabs from today’s increasing southwest wind or older, lingering wind slabs from several days ago. As always, avoid steep slopes with recent wind deposits.


      Over the next 12 hours.

As temperatures rise again today into the mid 20’s and some increasing high clouds, which may provide some greenhousing, we may see more wet sluffs on steep, sun-exposed slopes.


We should have increasing high clouds throughout the day in advance of our storm tonight and on Sunday. Today, ridge top temperatures will rise into the mid 20’s again and ridge top winds should blow 25 mph from the south. Tonight as a cold front crosses our area, we should get 7-12 inches of snow with perhaps that much again on Sunday, possibly lingering into Monday. It looks like a nice storm without too much wind to mess things up.
