Ogden Avalanche Advisory

Forecaster: Bruce Tremper


The long-awaited and long-anticipated, discount lift ticket sales have finally arrived.  Most of the local ski areas have donnated lift tickets to the Friends of the Utah Avalanche Center and you can buy them at a discount HERE.  All the proceeds go toward funding avalanche forecasting and education in Utah.  Thanks to Ski Utah, Backcountry.com and all the participating resorts for this valuable opportunity.  These tickets will go fast, so don't delay.  They make a great stocking stuffer and don't forget to put one in your own stocking.

Danger Rose Tutorial

Bottom Line for the Ogden area mountains:

The avalanche danger is mostly LOW today with pockets of MODERATE danger of lingering wind slabs along the upper elevation ridges.  But more importantly, the danger will rise to at least CONSIDERABLE on Saturday with the arrival of a strong cold front with lingering showers for the rest of the week.


High clouds and an approaching cold front are keeping our temperatures warm this morning with most mountains locations in the mid to upper 20's.  Winds have started to pick up a little but they should stay fairly reasonable today.  No, there is not a lot of snow, but things will change in a hurry starting Saturday morning.  Joshua Sprague and Doug Wewer have posted some good photos of the Mt. Ogden area on our website. 


There was very little activity yesterday with the exception of some minor wind slabs triggered by snow cats at the resorts along the upper elevation ridges in the Salt Lake area mountains.


      Over the next 24 hours.

Today will be the calm before the storm.  The avalanche danger is mostly Low today and the only places you could trigger an avalanche would be a few stubborn drifts along the upper elevation ridges.

But the main news is the future.  We have a very weak, pre-existing snowpack with a major change in the weather, which will arrive in full force Saturday morning.  This is certain to rapidly increase our avalanche danger.  Although the danger is mostly Low today, it will rapidly increase to Considerable on Saturday.

The smart avalanche folks are out today memorizing the pre-existing snowpack so they can have a good mental picture of where they will and won't trigger avalanches in the coming week.  For instance, most south facing slopes are completely bare and the slopes above 8,000' that face the north and east quadrants of the compass have very weak, settled snow on top of an old rain crust with very weak, faceted snow just under the rain crust.  You should page through some of the recent snow profiles to get the picture firmly burned into your brain. 

Most of our cagy network of observers are frightened of the very weak snow.  Here are some phrases from people who were out digging in the snow yesterday.  "Accidents waiting to happen."  "...will stay down in my basement."  "It will get exciting with the next big dump."  and "My big concern is the next storm cycle."


A major change in the weather is nearly upon us, and everyone in town is abuzz with the promise of a return to winter.  Saturday morning, the hammer should slam down with an old-fashioned, stong cold front complete with lightning and a howling blizzard for much of the day.  We should accumulate about a foot of new snow by Saturday night and there's a possibility of more snow after that with lake effect squalls.  After the cold front passes, it should feel like serious winter with mountain temperatures lingering in the single digits for most of the week.

The extended forecast calls for several more pulses of snow in the early part of the week, as most of the energy of the storm passes to the south of us, but we should be able to squeeze some snow out of the cold, unstable air on a south or southwest flow.
