Danger Rose Tutorial

There is a LEVEL 2 (Moderate) danger of wind slab avalanches mostly along the high ridges on north through east facing slopes. As always, avoid steep slopes with recent wind deposits. There is also a LEVEL 2 (Moderate) danger of wet avalanche activity on any steep slope with damp or wet snow and especially watch for roof avalanches again. Otherwise, the danger is LEVEL 1 (Low).


Winds were strong overnight. On Ogden peak winds blew 45 gusting to nearly 60 from the south and southwest, and 35 gusting to 45 on many of the lower ridges. Two inches of snow fell overnight and temperatures remain very warm, just below freezing on the ridges and in the mid 30’s in most mountain locations this morning. The snow surface remains a mixed bag with rock-hard wind slabs along the upper ridges, soggy and sun-crusted snow on the southerly-facing slopes and there’s still some smooth, creamy, dense powder on the wind and sun sheltered slopes.


There was a close call yesterday from a roof avalanche in Park City. A longtime avalanche professional noticed fresh debris on the north side of the Albertson’s and he also noticed only half the roof had released. He took some photos to send to us and someone told him it released just 10 minutes earlier. Then, a person came along wearing ear buds and he did not respond to the warning shouts from my friend. Just as he exited ground zero, the rest of the roof released barely missing him. He walked on oblivious to the thunderous noise of the roof avalanche, which likely would have killed him instantly. Rock on, dude.

There were no reports of human triggered avalanches yesterday from the backcountry. Avalanche control in Daly Chutes at Deer Valley produced a number of hard, deep, wind slabs from the strong winds yesterday afternoon.


      Over the next 24 hours.

Strong south winds from yesterday afternoon and overnight drifted snow onto north facing slopes along the high ridges. Strong winds will continue this morning from the south and southwest and should decrease this afternoon. So as always, avoid steep slopes with recent wind deposits.


      Over the next 24 hours.

Yesterday’s very warm temperatures and sun created widespread gloppy snow especially at low elevation, southerly facing slopes where lots of rollerballs and point-release sluffs came down in addition to the aforementioned, roof avalanches. Clouds and wind today should keep a cap on wet activity, but temperatures remain warm enough to mention it again. As always, avoid steep slopes when they are getting wet and soggy, and especially watch for roof avalanches again today.


Strong winds from the south and southwest will continue along the ridges blowing 45 on the high peaks and 35, gusting to 40 on most ridges. Winds should diminish by afternoon. We will have mountaintop-level clouds with light snow showers today with accumulations from a trace to 2 inches. More snow will fall north of I-80 than south. Temperatures will remain warm, in the mid 30’s. Saturday, we should be cloudy with light snow showers and moderate to strong southwest ridge top winds.

The extended forecast calls for another weak disturbance on Monday and another on the 10th.


If you trigger an avalanche in the backcountry - especially if you are adjacent to a ski area – please call the following agencies 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.
