Ogden Avalanche Advisory

Forecaster: Drew Hardesty


I'm holding an Open House at the Wild Rose tomorrow at 7pm for public comment on a new terrain rating scale and decision making tool for the Wasatch range.  I'm looking for feedback from all experience levels, especially beginners and intermediates.  For more info, go to our calendar off the home page. 

Bruce has a Science of Avalanches talk a the SLC REI on Thursday.  Check the calendar page.

Danger Rose Tutorial

We have a localized MODERATE for fresh and lingering wind drifts from the sustained northwesterly winds.  They’ve been strong for nearly a week now.  We have an isolated MODERATE danger for triggering a deep slab avalanche in north through east facing terrain at the mid and upper elevations. 


The stratus (horizontally vice vertically splayed) deck continues to drape itself over the Wasatch, leaving most in the Cottonwoods to wander around in the ‘fog’ in the upper reaches.    It has been a patchwork of cloud cover:  one guy claimed to see a rainbow a couple days ago.  At least the winds have ramped back up: they’ve pushed back into the 30mph range near 10k’, though they remain relegated to the highest elevations.  Temps are right side up: near freezing at 7000’ and about 20 degrees at 10,000’. 


No avalanche activity was reported in the ranges along the Wasatch front.   I wandered up into the Primrose Cirque on Timpanogos to look at the 30+ of debris from 270 degrees of starting zones from the Christmas cycle.  All that was left was bullet proof to trap-door hard slab over debris piles and cleaned out avalanche paths.  Conrad’s Kurtz couldn’t have said it better after looking deeply into Nietzsche’s abyss – ‘the horror, the horror’. At least someone’s glass is half full.


      Over the next 24 hours.

Most, but not all, of the drifts are pretty well welded into place.  Still, good habits save lives, and it’s still worth a bit of caution or a well-executed cut across the top of the slope before committing to anything.  With the break in some of the cloud cover, folks may actually be able to see where they’re going in the upper elevation terrain today. 


      Over the next 24 hours.

Not gone and not forgotten.  The graphic tells the whole story.  Very difficult to trigger, very difficult to survive.  Avoid thinner snowpack areas and steep, rocky terrain. 


May finally get some visibility today as the stratus cloud deck breaks up and a classic January inversion builds through the weekend.  Temps at 8000’ and 10,000’ will be 32 and 28 degrees, respectively.  The northwesterly winds are expected to stay moderate to strong, though relegated to the ridgelines. 


Yesterday, Wasatch Powderbird Guides did not get out and will likely not fly today because of wind and poor visibility.  For details, click here to go directly to their operations planning page.


The Utah Avalanche Center is hosting a Level 2 avalanche class in February which is now open for registration by going to the Black Diamond retail store.  More information is found off our education and calendar on the home page.



Beacon training parks are up and running!  On the Park City side, there is one at the top of Canyon’s gondola, in Little Cottonwood one is near the Snowbird parking structure on the bypass road, and in Big Cottonwood a training  park is at the west end of Solitude's lower parking lot.
