avalanche warning THIS AVALANCHE WARNING IS FOR CANYON MOUTHS AND FOOTHILLS OF CACHE...DAVIS...WEBER AND EASTERN SALT LAKE COUNTIES. STRONG WIND WILL CREATE POTENTIALLY DANGEROUS WIND SLAB AVALANCHE CONDITIONS IN LOW ELEVATION AREAS WHERE PEOPLE DO NOT NORMALLY SEE AVALANCHES. AVALANCHE DANGER IS EXPECTED TO INCREASE TODAY AND CONTINUE INTO WEDNESDAY. |
special announcement We will offer an Avalanche Awareness Class, for beginners and as a refresher for those already with some training, including a Field Day in the backcountry. Class begins on January 8 (evening) and all day Saturday January 10. Call Paige at 435-757-2794 for more information. |
current conditions As we used to say in New Hampshire, "it's wicked weather out there!" The Tony Grove Snotel reports 66 inches of total snow at the 8400' site containing 136% of average water for the date, and its -9 degrees this morning. The UDOT Hwy 89 Logan Summit weather station is showing southeast or down-canyon wind, gusting into the 30 mph range this morning and a chilly -5 degrees. Strong east winds overnight changed the landscape and drifted snow into strange and perhaps unexpected areas, especially at lower elevations and near canyon mouths.

description
The ongoing east wind event built wind slabs in strange and unexpected areas overnight. Of special concern will be lower elevation slopes in the foothills and near canyon mouths, but wind slabs likely built at all elevations and on slopes facing every direction. Wind slabs form in deposition areas on the lee side of ridge-lines and in and around terrain features like gullies, scoops, cliff-bands, and sub-ridges. These will appear rounded, perhaps chalky looking, and may be hollow sounding. Avoid fresh wind drifts and wind slabs on all slopes steeper than about 30 degrees. |

We're now in a tricky "Low Probability, High Consequence" situation. During the Solstice Storm, heavy wind-blown snow overloaded a weak layer consisting of faceted snow and surface hoar that was on the snow surface before the storm arrived. Dangerous and destructive triggered avalanches remain possible in some terrain steeper than about 30 degrees. The danger will be most pronounced on drifted slopes facing the northern half of the compass. Audible collapsing or whoompfing noises indicate dangerous persistent slab avalanche potential, and in some areas you still might trigger a dangerous avalanche remotely, from a distance, or worse from below. ****Video observation (snowpit) from Bobcat in the Wood Camp Area (12-27-2014)............HERE

weather It'll be sunny and wicked cold in the mountains today, with 8500' temperatures around -3 degrees and very strong east winds. This combination will create wind chills around 36 degrees below zero, which is dangerously cold obviously. Expect below zero temperatures again tonight with continuing fairly strong east northeast wind. Wednesday will be mostly sunny, with 8500' high temperatures around 15 and gradually diminishing northeast winds. Check out our one-stop weather page........HERE
