Danger Rose Tutorial

Most terrain has a MODERATE avalanche danger but it will rise toward CONSIDERABLE on slopes that are getting direct sun. I would continue to avoid steeper slopes that are getting direct sun and give cornices a wide berth.


Temperatures were in the low to mid 30s. Winds have been light from the southwest and are just increasing slightly. We had a period of high clouds move through that’s clearing out now. You should see a very shallow refreeze which won't last long this morning.


There was only minor wet avalanche activity reported from around the Ogden area mountains on Saturday


      Over the next 8 hours.

Avalanche activity related to heating is your biggest concern today. The heating is enough to activate some of the buried weak layers within the snowpack causing large dangerous slab avalanches. It seems that they are most likely in shallower snowpack areas such as slopes that have already avalanched this season. Up to now, they have mostly been on east through south through west facing slopes with only a hint of north to any of them. Northerly slopes will most likely join in the activity sooner or later. With warm weather in store for today, I won’t be surprised to hear about a natural or human triggered slab avalanche.


      Over the next 8 hours.

Be careful when approaching cornices as they will continue to get sensitive with the warming. They often will break back farther than you think they might.


We should see a period of mostly clear skies then some more thin clouds moving in later. Temperatures will get into the mid 40s at 8000 feet and upper 30s along the upper ridges. Southwest winds will gradually increase as the day goes on. This may help counteract some of the avalanche activity. There are a couple of disturbances that will move through over the next couple of days mostly just producing periods of clouds and southerly winds. Temperatures cool slightly.


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.
