avalanche advisory

wednesday march 28, 2007

The information in this advisory expires 24 hours after the date and time it’s issued, but will be updated Saturday March 31, 2007.

 

Good Morning! This is Craig Gordon with the Forest Service Utah Avalanche Center with your avalanche and mountain weather advisory for the western Uinta Mountains. Today is Wednesday, March 28, 2007 and it’s about 7:00 am. Regularly scheduled avalanche advisories for the western Uinta’s are available on Wednesday, Saturday, Sunday and all holidays and are brought to you in partnership with Utah State Parks and Recreation.

This advisory covers the terrain from Daniels Summit, to Mirror Lake, to the North Slope of the western Uinta Mountains. That’s a lot of turf and I can’t be in all of these places at once. Your snow and avalanche observations are critical to this program and help to save other riders lives by getting accurate information out to the public. I’m interested in what you’re seeing especially if you see or trigger an avalanche. Please call 801-231-2170, or email at [email protected] and fill me in with all the details. Thanks to everyone for all the great avalanche info and pictures this week.

 

Current Conditions:

Better late than never… our much talked about storm finally arrived yesterday afternoon and it looks like it should linger through Thursday. Wet heavy snow fell at the lower elevations and new snow totals at the trailheads are right around 3”. Up high however, close to 9” of lighter density snow has stacked up and temperatures crashed when the cold front arrived. Currently at 10,000’ it’s in the upper teens, in the low 20’s at 8,000’ and winds are generally out of the south, blowing 10-15 mph along the ridges.    

 

Avalanche Conditions:

This storm was kinda like our winter. You think it’s gonna happen, but it never quite materializes like it’s supposed to. While storm totals are a bit disappointing, there’s enough new snow to freshen things up a bit and slopes that didn’t have old tracks on them prior to the storm will be the ticket today. The wet instabilities we were worried about a week ago are locked in place for the time being and for now it’s back to a winter-like snowpack. Yesterday it was wild in the mountains with an occasional burst of lightening and raging southerly winds. It nuked for most of the day blowing in the 40’s and 50’s with gusts in the upper 60’s along the high ridges, but since there was hardly any snow available to blow around, old wind drifts won’t be a problem today. In addition, once the storm arrived, winds quickly died down, making today’s avalanche problems pretty straight forward and very manageable. Today I’d expect you’ll find sluffing on steep slopes and an occasional shallow wind drift may have formed early this morning on the leeward side of upper elevation ridges. In either case a well placed slope cut will give you a good feel for the stability of the slope. Even though the avalanche conditions seem pretty benign, as always, think about the consequences of triggering even a shallow avalanche and going for an unexpected ride down a steep slope.       

 

Bottom Line:

On most slopes throughout the range the avalanche danger is generally LOW today.  

Above tree-line there are pockets of MODERATE avalanche danger on slopes steeper than about 35 degrees, especially those with recent deposits of wind drifted snow. A MODERATE avalanche danger means human triggered avalanche are possible.

 

Mountain Weather:

A cold and slow moving Pacific storm will hang around the next 24 hours with our best shot of snow occurring today. It’s a complex system, which I never trust, so snow totals are dependant on the track of the storm. None-the-less we should see snow throughout the day with an additional 4”-6” a good bet. Temperatures will remain cold with highs at 8,000’ dropping throughout the day, only reaching into the lower 20’s and at 10,000’ in the mid teens. Overnight lows should be right around 15 degrees. As the center of the low drifts it will give us a variety of wind directions, first from the northeast this morning, becoming northwest later in the day and finally turning north late tonight into Thursday as the storm exits the state. Along the ridges wind speeds should remain in the 10-20 mph range with a few gusts in the low 30’s. Tonight an additional 2”-4” of snow is expected, then scattered snow showers by Thursday morning. Temperatures will warm into the mid 20’s on Thursday and partly cloudy skies with highs in the low to mid 30’s are expected for Friday.

 

Announcements:

I completed a preliminary investigation on the avalanche accident that occurred on Saturday Feb.17th in Buck Basin and it can be found here. Also there have been a number of close calls and unintentionally human triggered avalanches across the state in the past few days and pictures with descriptions of the events can be found here.

I’d like to thank Jim Shea, The Canyons and Colleen Graham from the Friends of the UAC for all their hard work in making the Know Before You Go fundraiser such a success!

 

The first annual western Uinta fundraising ride was an amazing success with nearly 150 people showing up for the ride alone!

I want to thank the Jim Shea Family Foundation, Rocky Mountain Sledders, the Wasatch Snowmobile Association and the Utah Snowmobile Association for all their tireless work in putting the event together. Thanks again to Team Thunderstruck and the Boondockers crew for helping out and schooling even the most experienced riders. Also, we couldn’t have pulled it off if it weren’t for Chad Booth who did an incredible job as both master of ceremonies and auctioneer. Finally, it wouldn’t have been possible without the support of everyone who attended… you folks are awesome!  

 

I want to thank the crew at Tri-City Performance in Springville along with Polaris and the Utah Snowmobile Association for partnering with the avalanche center and stepping up to the plate by providing a new sled for this season!  Click here, to see the new ride!

 

We installed Beacon Basin at the Noblett’s Trailhead and it’s good to go. I want to thank Doug, Bill, Jared, Brad and Wally who

unselfishly took time out of their powder day to help out the riding community… you guys rock!

 

Free avalanche awareness classes are available. Give me a call at 801-231-2170 or email [email protected] and get one scheduled before the season gets too crazy!
