Avalanche Advisory
Advisory: Salt Lake Area Mountains Issued by Evelyn Lees for Sunday - March 2, 2014 - 6:51am
bottom line

The AVALANCHE DANGER is CONSIDERABLE on any steep mid and upper elevation slope with recent drifts of wind-blown snow. Out of the wind drifted terrain, there is an overall MODERATE avalanche danger on steep slopes for wet sluffs with any sun or daytime heating, new snow slides and the isolated chance of triggering a deeper slide.




special announcement

Join us March 8th and 9th at Brighton Resort for the first annual VertFest and 11th annual PowderKeg. There will be gear demos, a series of backcountry skills clinics, free beacon clinics, a party featuring the band Salem from Boulder, CO and a great gear raffle. The VertFest is a benefit for the Utah Avalanche Center. Click Here to find out more and to sign up for the backcountry clinics.

Show Us You Know the Snow: US & Canadian avy groups have a challenge to sidecountry riders: Use your camera to tell a short video story about how your crew gets ready to safely ride beyond the resort boundary. Videos will be posted & promoted by GoPro & other partners. The contest will run till Mar 21. The winner will be determined by a combination of most views & an expert panel. Prizes include: 2 days at Monashee Powder Snowcats, 2 4-day Gold Passes to any US resort, a Backcountry Access Float 22 airbag, gear from Backcountry.com, editing help and support from Sherpas Cinema, & more. Winners will be announced in late March. . Details at knowthesnow.com Please share this with your friends

current conditions

Under mostly cloudy skies, a few flakes are still falling in the mountains. Temperatures are mostly in the 20’s, and the westerly winds are so light –even the highest ridgeline stations are averaging less than 20 mph. The Ogden mountains were the clear winners for snow in the past 24 hours: 7 – 11”. The Park City, Provo and Cottonwoods have received about 2 to 6” of new snow in the past 24 hours.

Approximate storm totals since Thursday are:

recent activity

There were several new snow slides triggered in the backcountry yesterday - 2 in the east bowl of Silver Fork, 1 Grizzly Gulch, and possibly 3 outside of Brighton’s area boundary. The resorts had widespread new snow activity, from both ski cuts and explosives. Some deeper slides, to 3 feet, were triggered below cliff bands, where the graupel has pooled.

Wind Slabs People will still be able to trigger 1 to 2 foot deep wind drifts, though they will be much more stubborn today. Strong winds loaded the snow into deeper, more erratic pockets, both along ridge lines and down into the mid elevations and into open bowl. These isolated drifts will vary greatly over very short distances, with deep pockets in one spot, and the slope scoured clean in another. Dense and cracky snow is a clue you are in a drifted area.

Storm Snow Out of the wind drifted terrain, most of the new snow instabilities should have settled out, but use caution on steep slopes. Also identify and avoid places where the graupel has rolled down cliffs or steep slopes and pooled. Deeper slides could be triggered in these spots.

Breaks in the clouds are possible today, and even brief periods of sun will allow the snow to rapidly heat, especially on steep sunny slopes and on all low to mid elevation slopes. Wet snow sluffs will become very easy to trigger. Have an exit plan that avoids steep, sunny slopes and low elevation terrain traps should the snow heat up.

I am still suspicious that in a few isolated places a slide could be triggered on one of the more deeply buried faceted layers, probably by a large trigger such as explosives, multiple snow machines or the weight of a new snow slide. Traditionally shallower snow pack areas – like Mt Aire, Mineral Fork, parts of Mill Creek – are possibilities, as are shallow rocky areas and hanging snow fields.

weather

A moist westerly flow will persist over northern Utah through Tuesday, with very weak disturbances rippling through. One is ending this morning, and today skies will be overcast to partly sunny, with 10,000’ temperatures warming into the mid-20s, and 8000’ temperatures warming to near 30. The westerly winds will remain light today, with even the highest peaks averaging 25 mph or less. Winds will increase slightly tonight as another very weak disturbance moves through, with the possibility of a few snow showers tonight, especially north of I-80.
