current conditions The Tony Grove Snotel reports 62 inches of total snow at the 8400' site containing 133% of average water for the date, and its 13 degrees this morning. The UDOT Hwy 89 Logan Summit weather station is showing fairly light east-northeast wind, and a chilly -3 degrees. Strong east winds on December 30 changed the landscape and drifted snow into strange and perhaps unexpected places. But, there's still plenty of nice settled powder, especially in more sheltered terrain in the Logan Area Backcountry. Strong east wind caused substantial drifting at all elevations. Logan Peak and Mill Hollow (12-30-2014). ****Watch Cold East Wind video observation from 12-30-2014............HERE

description
Avoid wind drifts and wind slabs on all slopes steeper than about 30 degrees. The recent strong east wind event built wind slabs in strange and unexpected areas. Wind slabs tend to 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. The wind slabs I looked at yesterday were fairly well behaved, but I avoided those on steeper slopes. Some cracking has been reported in the zone, but local observers are also avoiding steep drifted slopes.

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 are becoming less likely but remain possible in some drifted terrain facing the northern half of the compass on slopes steeper than about 30 degrees. I have found weak snow in areas that were shallow in December, and observers have reported post-holing in areas with non-supporting snow, and others of triggering audible collapses. West facing slopes and rocky shallow mid-elevation slopes appear the most suspect currently. These will be areas to keep an eye on as the season progresses. *****Video observation from Franklin Basin in the Beaver Mountain Backcountry from 12-31-2014...........HERE

weather New Years Day will be sunny, with 8500' temperatures around 20 degrees and diminishing east winds. It'll be mostly sunny tomorrow, with high temperatures around 20 again and light southwest winds. A bit of snow is possible for the upcoming weekend starting tomorrow night, but accumulations look rather light at this point. Check out our one-stop weather page........HERE
