Ogden Avalanche Advisory

Forecaster: Bruce Tremper


We need your help! Would you like a great mobile avalanche app? A new, slick website look? A better, easier-to-use information network? And something that all avalanche centers can use? There could be an app for that.

We are applying for a grant to help unify our website, email, SMS, and social media alerts and create an open source platform that could be used by any avalanche center. Check out the link.

Hot tip: we still have some discount lift tickets for Snowbird and Alta available through Backcountry.com, which you can find HERE.

Danger Rose Tutorial

The avalanche danger is MODERATE today for recent deposits of wind drifted snow. As always, avoid any steep slopes with recent wind drifts. There is also a MODERATE danger for deep slabs in the upper elevation northwest, north, northeast and east facing slopes.


With apologies to Sarah Palin, among others, today we may finally get a little lipstick on the pig. Snow should begin this morning and give us a thin, new paint job--perhaps 3 inches and it should all be over by afternoon. It’s hard to get excited about such a wimpy event but after a number of days of very poor snow surface conditions, almost anything will pass for excitement.

Yesterday, there was slide-for-life frozen crusts on most aspects, which did not soften up until late in the day because of the cloud cover and strong wind. There are scraps of dry, old, settled snow on straight north slopes above about 10,000’.


There was no avalanche activity yesterday with the exception of an explosive-triggered, wet slab yesterday afternoon in Big Cottonwood Canyon at 9,700’ on a west facing slopes 2’-3 deep x 100’ wide.


      Over the next 10 hours.

With colder air blowing in today, it should lock up any wet avalanche activity, so the main avalanche problem will be the fresh wind slabs created by the dusting of new snow combined with strong southwest winds. These will be deposited on top of hard, frozen, sun crusts, which may be quite slick, so the wind slabs will be more sensitive than if the storm started in the heat of the afternoon, when they would bond better with a wet surface.

As always, avoid any steep slope with a recent wind drift. They will be 6 inches deep--perhaps as much as a foot along the ridges. Winds during the passage of a cold front are often gusty and swirling, so they may be deposited on a variety of aspects but especially on the north through east facing slopes along the ridges.


      Over the next 24 hours.

There is still the possibility of deep slabs in the upper elevation, thin snowpack areas such as repeater slide paths. These will be low probability - high consequence avalanches. In other words, hard to trigger but if you do, they will be very large and unsurvivable.


Light snow showers and gusty winds will occur this morning and the snow showers should end by afternoon, leaving us with perhaps 3 inches of new snow. Woo Hoo! Temperatures will continue to drop and level off in the mid 20's and wind will blow 25 mph from the south, turning to the southwest later in the morning and they will likely gust into the 40's

Tonight and tomorrow should be partly cloudy with the overnight low near 20 and the temperature should rise to near freezing on Tuesday. We have a few clouds and a slight chance of precipitation on Thursday and the possibility of a stronger cold front on about April Fools Day.


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.
