Salt Lake Avalanche Advisory

Forecaster: Evelyn Lees


We have three different events tonight. With our partners, The Friends of the Utah Avalanche Center, Harry O's in Park City is having the Powderwhore show along with music, dancing and a huge raffle, or you can head downtown to Canyon Sports at 517 S 200 W to sample beer from the Red Rock Brewery made especially for the Utah Avalanche Center at the 1st annual Canyon Sports Brewski Bash, with food, music and prizes. There's also a free avalanche awareness talk at 7 pm at the Sandy REI. Check out our calendar off the HOME page for more details on all the upcoming events.

Danger Rose Tutorial

The avalanche danger is generally LOW, with pockets of MODERATE in wind drifted, high elevation terrain and in graupel pools below cliffs where it may be possible to trigger small slides within the new snow. On steep slopes be prepared for shallow surface sluffing as you descend.


I have measured out my snow with coffee spoons...and found small totals of 1 to 2 new inches this morning. Light snowfall is continuing, and temperatures are currently in the mid 20's at 8,000' and down into the teens at 10,000'. The winds are generally from a southwesterly direction, averaging less than 10 mph, with only a few of the highest peaks having speeds in the 15 to 20 mph range. Turning and riding conditions were remarkably improved yesterday by the 3 to 5 inches of dense, supportable graupel from Tuesday. Though I have to admit, with the combination of a shallow snowpack and flat light, I scraped several of the barely consealed rocks.


No avalanche activity was reported from the backcountry yesterday, and even with explosives, the resorts only pulled out a few small graupel pockets.


      Over the next 12 hours.

The upper snow pack is weak, with layers of thin ice crusts and small angular facets. However, the recent 3 to 6” of new snow is not enough weight to cause failure of these facet/crust sandwiches. But it will be possible to trigger a few small pockets of new snow in areas where the graupel has pooled – either drifted by the wind along the higher ridge lines or below cliff bands, where it has rolled down and collected in piles. The only other avalanche concern is the possibility of triggering a few shallow sluffs on steep slopes.


Skies will remain mostly cloudy today, with snow showers adding another 1 to 3 inches to the overnight accumulations. Winds will be shifting to the northwest, then north, remaining in the 10 to 20 mph range, with gusts to 30 and occasionally 40 mph. Slowly clearing skies tonight, with temperatures dropping down into the low to mid teens. Then warm, dry high pressure moves in on Friday, lasting through the weekend. Another weak cold front is forecast around Monday.
