Salt Lake Avalanche Advisory

Forecaster: Evelyn Lees

SPECIAL ANNOUNCEMENT

Whole Foods Market in Cottonwood Heights is helping to raise funds for avalanche education. The store, at 6930 S. Highland Drive, will donate 5 percent of its net sales on Jan. 13 to the Utah Avalanche Center. We will present a 50-minute “Know Before You Go” safety presentation there at 7 p.m.

Are you prepared to deal with an injury in the backcountry? A Wilderness First Responder course could save your partner's life someday. Wasatch Emergency Medical Training is offering a course beginning January 17 & is donating a portion of the proceeds to the FUAC. Contact Mike atescobadelmar@gmail.comfor details.


BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

There are pockets of LEVEL 2 (MODERATE) avalanche danger on mid and upper elevation slopes for small wind slabs and for loose snow sluffs, especially on shadier northwest through southeasterly facing slopes. Terrain – meaning where a ride would take you if you’re knocked off you feet - will determine the seriousness of these small avalanches. Keep a sharp eye on the wind – if there is any increase where you, the avalanche danger will rapidly increase. Out of the wind affected terrain and off the steepest slopes, the avalanche danger is generally LEVEL 1 (LOW).


CURRENT CONDITIONS

Under mostly cloudy skies, temperatures seem downright balmy compared to yesterday’s negative territory, with most stations reporting in the mid to upper teens. The southwesterly winds remain light at most locations, with only the most exposed peaks averaging 15 to 20 mph (to 25 mph in the Ogden area mountains), with gusts 30 to 35 mph. Turning and riding conditions remain excellent on untracked wind and sun sheltered slopes.


RECENT ACTIVITY

Yesterday’s slight increase in winds was just enough to blow around the low density snow, and there were isolated reports of easily triggered and natural small soft wind slabs from the Ogden and Provo area mountains. Both surface hoar and low density snow were identified as the culprit weak layers. There were also easily triggered sluffs of the loose, weak surface snow on steep slopes.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Triggering a small new wind slab in radical terrain or a poor position above cliffs, trees or a gully will be the most likely way to get in trouble today. With low density snow available for transport, it only took a slight uptick in winds speeds to develop a few sensitive wind drifts along both higher ridgelines and mid elevation break overs yesterday. These isolated soft drifts may be a bit firmer and more stubborn today.


THREAT #2

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

Sluffing on steep slopes in the weak surface snow composed of near surface facets and surface hoar will continue today. Once again, the danger is dependent on terrain, so think about where you might go if you’re caught and carried. And speaking of loose snow - in some places the surface foot or more of snow is so consistently weak it is starting to “sand box” - a casual term used for loose unconsolidated sugary snow that you can sink into and wallow around in.


MOUNTAIN WEATHER

Skies will be mostly cloudy today and tonight as a weak splitting storm system leaves northern Utah in the middle. Temperatures will warm today into the upper 20’s at 8,000’ and to near 20 at 10,000’. The southwesterly winds will generally be in the 10 to 20 mph range, with gusts less than 25. But the highest peaks and ridges will have averages to 25 mph with gusts to 35. A fast moving disturbance, still on track for Thursday night, is forecast to produce 3 to 5” of snow and be accompanied by slightly stronger west to northwesterly winds. A moist west to northwest flow through the weekend may bring periods of occasional light snow.


GENERAL ANNOUNCEMENTS

If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following teams to alert them to the slide and whether anyone is missing or not. Rescue teams can be exposed to significant hazard when responding to avalanches, and do not want to do so when unneeded. Thanks.
