There's a few inches of fresh, super light powder in the Logan Zone, but southwest winds picked up significantly overnight, building sensitive cornices and drifting the low density snow into slabs in avalanche starting zones. Upper elevations in the Logan Zone picked up over 2 feet of snow with over 4 inches of SWE with the Valentines Storm.
The Tony Grove Snotel at 8400' reports 6" of light new snow with .4" SWE in the past 24 hours. It's 7º F this morning and there's 90" of total snow containing 106% of average SWE for the date. It's -1º F, at the 9700' CSI Logan Peak weather station, and southwest winds are currently averaging around 27 mph, gusting to 50 mph.
A potent winter storm will settle into the Great Basin today, then remain over the region through late in the week. Heavy snow associated with this storm will concentrate mainly across the southern two-thirds of Utah late today through early Friday. Expect snow today, with 3 to 5 inches possible. High temperatures at 8500' are expected to be around 17º F, and with 20 to 25 mph southwest winds, wind chills will be around -20º F. Tonight temperatures will be around 3º F, with 10 mph southwest winds, veering from the east-southeast after midnight. Mostly cloudy tomorrow, with a chance of a little snow, high temperatures around 16º F, and increasing 20 to 25 mph east winds with gusts in the 40s!
Numerous natural avalanches involving heavy, drifted, and rain-saturated snow were observed this weekend on slopes at all elevations across the Logan Zone. Observers report triggering small soft slabs and sluffs including the soft new snow in steep terrain in the past couple days.
This large natural hard slab avalanche was observed Friday afternoon in upper Providence Canyon. The crown looks to be 6 to 8 feet deep and it's about 1000' wide.
There were several large avalanches at low elevations on the east side of the Wellsville Range involving wind drifted and rain saturated new snow. This one is at around 6000' on Maple Bench.
