This morning, it's 24° F at the Tony Grove Snotel at 8400 feet, with 27 inches of snow that's continuing to settle after this weekend's storm. Overnight, moderate winds were sustained, shifting from the northwest to southwest while gusting into the 40s mph. Overnight mountain lows hit 18°F on Paris Peak, and highs reached just above freezing at 33°F on Logan Summit.
Over the weekend, the wet, warm, and windy storm that peaked from Friday night into Saturday morning dropped 2.8 inches of water and about a foot of dense, heavy snow on top of an already weak, faceted snowpack from our snowfalls October through November. This strong slab of storm snow sitting on top of the weak old snowpack structure is responsible for many natural avalanches that were large enough to bury a person, as well as too many other red flags—like whumfing and shooting cracks—to count since Friday. For more info on those avalanches, head to the natural activity section below.

Looking ahead, Northern Utah stays under northwesterly flow. There's a shortwave trough that's passing through NE Wyoming tomorrow, which will largely miss us. However, it will bring increasing winds from the NW, as well as the potential for some moisture to hit the Logan zone. While it's not going to be as significant as last weekend's storm, there's a possibility of up to 0.5 inches of water to fall in the Bear River Range by Wednesday evening. Snow levels will remain high as the temperatures gradually warm throughout the week, so don't count on any large accumulations of snow.
A rider reported triggering a 6 foot deep avalanche on a NE-facing slope near 8800 feet yesterday while riding near Double Top Mountain. The slide broke on weak, old faceted snow that was buried during this weekend's storm. We think it was the debris that piled up deeply. In the photo, the avalanche slab looks to be around 2 feet deep. His full observation is HERE.
-Pro observers Katz and Applegarth spotted a number of large natural slides that likely ran during the height of the storm Friday into Saturday while traveling in the Tony Grove Lake area yesterday. The avalanches broke wide and far on the buried persistent weak layer above 8800 feet on northwest through east-facing slopes. You can find more of their obs HERE and HERE. Toby and I observed additional slides in sheltered terrain on similar aspects at mid-elevations that were also large enough to bury a person, see our ob HERE.
