Ogden Avalanche Advisory

Forecaster: Brett Kobernik


We've continued the SPECIAL AVALANCHE ADVISORY is for the mountains of northern and central Utah, to include all of the Wasatch Range, the western Uintas and the Wasatch Plateau. A WARNINGis in effect for the Bear River Range near Logan. Rain on snow is creating unstable conditions below around 8500 feet in elevation. People should avoid all gullies and stay out from under any steep slope to avoid being caught in natural avalanches. At the upper elevations human triggered avalanches are likely especially on slopes approaching 35 degrees in steepness that face north through southeast.

Danger Rose Tutorial

There is a Level 3 (CONSIDERABLE) avalanche danger on all slopes that are approaching 35 degrees or steeper. Wet avalanches at the lower elevations dictate to stay out of all gullies and out from under all steep slopes. Natural avalanches may pile up deep debris. The possibility of triggering a slab breaking into persistent weakness at the upper elevations dictates we stay off slopes approaching 35 degrees in those locations.


It’s a complete mess out there. We’ve added one to two inches of water mostly in the form of rain over the last 12 hours with only a few inches of snow. There is some sort of ice/riming event going on at the higher elevations. The winds have really ramped up over the last couple of hours with gusts to near 40 mph at the base of Snowbasin. Temperatures are in the mid 30s at almost every station.


No activity was reported from the Ogden area mountains on Sunday.


      Over the next 24 hours.

My biggest concern for today is wet avalanche activity in the mid and lower elevations especially terrain below 8500 feet. In many areas the snowpack is saturated with water from rain. This weakens bonds between grains making things unstable. People should avoid being in any gullies or under any steep slope in the low to mid elevations where the snow is wet. I’m somewhat weary of the mid portions of the Mill Creek Canyon groomed road up above Elbow Fork. There is steep terrain that threatens the road and it is probably best to avoid that area today.


      Over the next 24 hours.

I’m not quite sure how the persistent weakness in the upper elevations is going to behave today but you must treat it as guilty until proven innocent. A persistent weakness with and inch to two inches of water added on top of it is not a sign of stability. It may do nothing but we can’t prove that at this time. Leave it alone today. This rain and warm weather event should be just the ticket for helping heal the persistent weakness we’ve been talking about but temperatures need to cool first. The weakness may not totally heal in some of the mid and upper elevations but the distribution of the problem should be greatly diminished.


We’ll remain in a somewhat moist west northwest flow today but most of the rain and snow is past. There’s still a chance for a bit this morning but should decrease as the day goes on. Winds are going to continue to howl from a westerly direction through mid day. Temperatures will remain mild and start to cool this afternoon and drop into the teens at the higher elevations tonight. The next chance for snow is Tuesday into Wednesday with about a 6 inch event expected at this point.


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.
