bottom line Heightened avalanche conditions exist and there is a MODERATE (or level 2) danger in the backcountry. You could trigger wind slab avalanches on steep slopes with recent deposits wind drifted snow, and cornice falls are possible. Rising midday temperatures will also create heightened avalanche conditions in steep terrain, with triggered wet and/or heat related avalanches possible on steep slopes. Evaluate the snow and terrain carefully, avoid steep drifted terrain and steep slopes with warming or saturated fresh snow.

special announcement
Yesterday, five UDOT forecasters and three UAC forecasters visited the site of the very tragic fatality of UDOT avalanche forecaster Craig Patterson on Thursday. We posted a preliminary report with photos on our website. Our hearts go out to his family and all his other friends. Craig was widely loved and admired by all. One of the rescuers summed it up best, "It was a very small avalanche with a very bad ride." Note: all media inquiries on this accident should be directed to UDOT. |
current conditions The Tony Grove Snotel reports 36 degrees and 55 inches of total snow, containing 63% of average water for the date. The station recorded a couple feet of accumulation and 3.2 inches of snow-water equivalent in the last week, (since last Friday morning.) The CSI Logan Peak weather station at 9700' reports 23 degrees and sustained southwest winds averaging close to 30 mph this morning. Most of the fresh snow from earlier in the week will probably be a bit crusty this morning, and you'll find crusts of varying thicknesses and supportability on slopes facing all directions and elevations.

recent activity Here is the preliminary report on Thursday's tragic and fatal avalanche accident in Big Cottonwood Canyon in the salt Lake Area Mountains, which killed friend and fellow avalanche forecaster, Craig Patterson. The deadly wind slab avalanche wasn't all that big, but it took him down for a very nasty ride in steep terrain. ......... Here
No significant new avalanches were reported recently in the Logan Area, but I certainly wouldn't be surprised to hear of or observe evidence of some from this week. Here's a link to our updated Avalanche List.
