Salt Lake Avalanche Advisory

Forecaster: Brett Kobernik

SPECIAL ANNOUNCEMENT

Dangerous avalanche conditions persist in many Utah mountain locations. Human triggered avalanches are likely to almost certain on many steep slopes. These avalanches may be triggered from a distance and are likely to be very large and unsurvivable. People without expert level avalanche assessment and route finding skills should continue to avoid the backcountry.


BOTTOM LINE

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

Danger Rose Tutorial

The avalanche danger remains HIGH today, and human triggered avalanches are likely on many slopes of 30 degrees and steeper, in mid and upper elevation terrain of all aspects. Avalanches can be triggered from a distance - from below or from adjacent slopes to the side. We still are not recommending travel in avalanche terrain.


CURRENT CONDITIONS

Temperatures have been on the rise over the last 24 hours and are generally around 20 degrees in many mountain locations. Gusty ridgetop winds from Saturday have slowed a bit only averaging in the 20s at the most exposed locations. A trace to a couple of inches of snow accumulated over the last 24 hours.


RECENT ACTIVITY

People are giving the mountains their due respect right now and not many human triggered avalanches were reported from Saturday. There was one significant slide that was most likely triggered remotely by a ski touring party as they were walking away from the bottom of Wills Hill in Willow Creek of Big Cottonwood canyon. They had avoided skiing the slope and it had not released at 3pm when they were leaving. One of our observers noted that it had avalanched by 3:30. It is very likely that the skiers initiated a collapse that triggered it while traversing on adjacent terrain.

Visibility on Saturday gave us glimpses of the natural avalanche cycle that occurred during the last storm. Some of the notable avalanches that were viewed on Saturday include Cardiac Ridge, High Ivory, the northwest aspect of Gobblers Knob that came out huge, and the northeast face of Little Water Peak which is a different slide then the accident from Friday.

More photos will be posted this morning.


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

While the most recent storm did produce a good amount of snow it wasn't the whopper that we needed to end all of our persistent weakness concerns. It is most likely that the avalanches will be less frequent and not as “hair trigger” as they've been. I'm afraid that some people may chance it and get away with getting onto bigger slopes which may entice others to try it as well. Tracks on a slope are by no means any indicator that the slope is stable. Keep in mind that any avalanche that you trigger has the potential to be very large. Make no mistake that the current snowpack structure alone dictates continued caution. Patience is a necessity that all backcountry travelers have to practice if you plan on doing it for the long haul. We are in a period where we need to stay in check for a while longer.


MOUNTAIN WEATHER

We'll see partly to mostly cloudy skies today with light snow showers possible this morning. Temperatures will be in the mid 20s and ridgetop winds will be in the 5 to 15 mph range gusting into the 20s and 30s along the more exposed locations. Temperatures warm even more on Monday with a weak storm system that will move through Monday evening.
