MODERATE: Heightened avalanche conditions exist and dangerous human triggered avalanches are possible on shady upper elevation slopes that had snow before Thanksgiving. Triggered avalanches involving wind drifted snow are also possible at upper elevations. The snow is much more stable and there are very nice powder conditions elsewhere.
We've noted an increase in stability in the past few days, and weak snow from early November is now deeply buried at upper elevations. Dangerous human triggered avalanches running on a persistent weak layer are still possible in shady upper elevation terrain.
Shallow but loose faceted snow lurks under the Thanksgiving slab, and fresh powder is piling up on north facing slopes at upper elevations.
Join us on Wednesday December 5th to celebrate the coming of winter! Our 15th Annual Pray for Snow Party and Fundraiser is at The Cache with music from Two Headed Trout, pizza from Lucky Slice, beverages from Moab Brewery, and a raffle and silent auction of amazing donated items. Thanks for your support of avalanche awareness and education. We look forward to seeing you! Tickets available online: CLICK HERE.
No new avalanches were reported in the Logan Zone since a natural cycle at upper elevations on Thanksgiving weekend. We could see evidence of some natural loose sluffs from Sunday in very steep terrain near Tony Grove Lake.
The Tony Grove Snotel at 8400' reports 15º F and there's 37"of total snow, containing 114% of average SWE for the date. It looks like it's snowing lightly in the mountains this morning. It's 14º F at the 9700' CSI Logan Peak weather station and a south wind is blowing around 25 mph.
A snow squall is moving northward through the zone this morning, and it may stall, bringing an inch or two of accumulation to Cache Valley and the surrounding mountains today. Expect cloudy conditions, with high temperatures at 8500' around 20º F and 10 mph southwest wind. Snow showers may continue into the evening, but little accumulation is expected overnight. Low temperatures around 13º F are expected with light and variable wind. Tomorrow will bring mostly cloudy skies, with high temperatures around 22º F and 10 mph southwest winds.
Areas with heightened avalanche conditions exist on upper elevation slopes that held snow before the Thanksgiving storm. Dangerous human triggered avalanches remain possible. Much less danger and excellent powder conditions exist where is no old pre-Thanksgiving snow, but you'll need to watch for fresh wind drifts in steep terrain.
The Tony Grove Road is open but not maintained for winter travel of wheeled vehicles. Lots of folks made it up there over the weekend on sleds, and you won't get far if you try to drive up today.
Beaver Mountain is glad to allow non-motorized uphill traffic. You can find generally safe conditions in lower angled terrain, and help pack out the ski hill. Nice powder conditions and good coverage were reported from over the weekend. Remember, before it opens, Beaver Mountain is the backcountry.
Now is a great time to practice companion rescue techniques with your backcountry partners. Here is our practice video.
