Salt Lake Avalanche Advisory

Forecaster: Brett Kobernik

SPECIAL ANNOUNCEMENT

A Special Avalanche Advisory continues for all the mountains of Utah today. Large avalanches can still be triggered by people on slopes approaching 35 degrees. These avalanches are responsible for two fatalities this week. A very persistent weak snowpack will remain unstable for some time to come. People should continue to avoid steep avalanche terrain this weekend.


BOTTOM LINE

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

Danger Rose Tutorial

Because of the severity and sensitivity of the large avalanches occurring, there are pockets of a HIGH danger in the backcountry. Slopes approaching 35 degrees that face west through north through southeast should be avoided. Do not go below these slopes either as many of the avalanches are running well into the bottoms of the avalanche paths.


CURRENT CONDITIONS

Temperatures are around 20 degrees at many mountain locations and winds are light and variable but mostly from the south or southeast along the peaks.


RECENT ACTIVITY

A snowmobiler is in critical condition after triggering a large avalanche on Grandview Peak that buried him. Wasatch Powderbird Guides were in the area and assisted in the rescue by performing a beacon search and digging up the victim. (Details are HERE)

One other avalanche occurred during helicopter explosive testing in Mary Ellen Gulch on Friday. It produced an avalanche that was 3 to 4 feet deep and 400 feet wide running full track.

UPDATED: There was another very close call with a snowmobiler in Snake Creek on Friday. He triggered an avalanche 4-6 feet deep and 500 feet wide while descending a steep slope. He tried to out run it but was knocked off and ended up partly buried. His sled was reported as fully buried. More details to come (Snake Creek Accident)


THREAT #1

WHERE PROBABILITY SIZE TREND
      Over the next 24 hours.

The main concern in the backcountry is the threat of triggering a large avalanche breaking into weak snow near the ground. These avalanches can be 2 to 4 feet deep and hundreds of feet wide. The message should be loud and clear: stay off of the steep slopes for a while still.


MOUNTAIN WEATHER

We'll have partly cloudy to mostly cloudy skies today. Ridgetop temperatures will be in the mid to upper 20s. Winds start out light and increase through the day from the southwest. A small storm will move through the area tonight into Sunday producing a few inches of new snow. A number of disturbances will move through next week with none of them really looking like they'll produce much in the way of snow accumulation.
