I'm holding an Open House at the Wild Rose tonight 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 or click the link to the left for upcoming events. 

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.  Wet activity will increase with the solar warming by late morning.  Avoid the steep sunny exits by early afternoon.

The velvet blanket of stratus now long gone, skies are again clear and inversions are beginning to take hold.  Temps are in the mid to upper twenties.  I trust that this will be the northwesterly winds’ last gasp, before fizzling out under the advancing dome of high pressure.  They’re still humming along at 20-25mph and gusting to 30, but, again, confined to the highest elevations.  Certainly, the moist northwesterly flow and winds rimed and damaged most of the terrain, but you can find soft settled powder at the sheltered mid and low elevations.  The rime crust is from Ogden to Park City and the Salt Lake mountains and more pronounced on the mid and upper elevation windward aspects. 

We heard of no activity in the Provo mountains.  Activity in the central Wasatch amounted to some very minor wet rollerballs on the sunnyside and a couple explosive-induced shallow hard slabs.  DOT in Big Cottonwood Canyon spotted a couple new wind pockets that released high in northeast facing Stairs Gulch – high, lonely, steep, rocky windswept terrain. 

Bluebird high under the building high pressure.  Winds should start to relent some by the afternoon and blow 20-25mph from the north.  8000’ and 10,000’ temps will rise to the low thirties and upper twenties, respectively.  High pressure and a building inversion will take hold through at least the weekend, with the weather models in some agreement on a transition to more storms for later next week.

Yesterday, Wasatch Powderbird Guides' operations page is here.

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.
