Ogden Avalanche Advisory

Forecaster: Bruce Tremper


Through a generous donation by Backcountry.com to our partners the Friends of the Utah Avalanche Center we will continue forecasting for the next couple weeks. It will be a combination of early morning weekend forecasts and mid week afternoon updates, with weekend only updates for the Logan and Uintas area mountains. Thank You!!

Utah Department of Transportation will likely do avalanche control Thursday morning in Provo Canyon between about 10 am and noon. Be sure to stay clear of Bridal Veil Canyon and other Provo Canyon slidepaths on Thursday.

There is no overnight closure planned for Little Cottonwood Canyon but they may do some avalanche control in the morning, depending on storm conditions.

Danger Rose Tutorial

There is a MODERATE (Level 2) danger of avalanches from the overnight storm caused by three types of avalanches: 1) layering within the new snow, 2) wind drifted snow and 3) wet avalanches on sun exposed slopes if the sun comes out.


Yep, we have yet another snow storm arriving tonight. Imagine that. The forecast is for about a foot of snow overnight. The underlying snow is mostly stable as it heated up and settled significantly with the last inter storm warming.


The only activity reported from today was in the Provo area mountains on Bunnels Peak when an intentionally-dropped cornice pulled out a wet slab in the heat of the day. Otherwise, it seems that much of the widespread wet sluffs that occurred a couple days ago have settled out.


      Over the next 24 hours.

The main problem will be storm snow falling overnight. It is coming in with lots of wind and graupel, so look for any sensitive layering within the new snow. You can easily test for this. Just quickly dig down with your hand and cut out small blocks and pull on them. You can also jump on small, test slopes. Violent storms like this commonly produce soft slab avalanches due to variable layering during the storm, but since the underlying snow is so warm and wet, it should settle out and stabilize quite quickly. This should occur on all aspects and elevations.

The new snow should fall on a mostly stable, but wet, underlying snowpack. We have not seen many deep releases in awhile but some of the deep layers are still lurking in some upper elevations slopes. (See Brandon Dodge's snowpit from today.)


      Over the next 24 hours.

As usual during a storm, you will find fresh wind slabs especially in upper elevation, wind exposed terrain. Wind slabs look smooth and rounded and often feel punchy or sound hollow. You should stay on non-wind drifted slopes.


      Over the next 24 hours.

We expect that this storm will be a quick-hitter and should clear out during the day on Thursday. The sun is very strong this time of year, so expect the new snow to quickly form damp to wet sluffs on steep, sun exposed slopes.


The strong cold front tonight is forecast to put down about a 7-14 inches of new snow overnight. It will be windy and gusty at the beginning of the snow with layers of graupel deposited. We expect the storm to be mostly over by morning and clear out during the day. We should see increasing sun throughout the day with temperatures staying fairly cool at around 25-30 degrees. As usual, you can find more details in the Cottonwood Canyons forecast.

Weather should remain unsettled for the next week but with no big storms in the forecast, just typical spring off-and-on showers with sun in between.



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.
