Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Thursday morning, March 6, 2025
Heavy snowfall and drifting by south winds created dangerous avalanche conditions overnight and will continue to elevate the danger in the backcountry today. There is CONSIDERABLE danger on all mid and upper elevation slopes. Natural avalanches are possible, and people are likely to trigger loose and soft slab avalanches of storm snow up to 2 feet deep on slopes steeper than 30°.
Evaluate the snow and terrain carefully, make conservative choices, and continue to practice safe travel protocols. Avoid wind-drifted slopes and large overhanging cornices.

Special Announcements
March kicks off our Spring Campaign! If everyone in Utah’s backcountry community donates the cost of something they regularly enjoy on an adventure—like a dawn patrol burrito, a backpack snack, or post-ride trailhead drinks—we could fund not just one but two forecasters for the entire season! Donate here.
Join the UAC on Thursday, March 6th at Brewvies in Salt Lake for friends, drinks, prizes, and an action-packed film! Alpine Assassins is a movie about incredible backcountry sledding and adventure. Doors open at 6:30 PM. Get your tickets HERE.
Weather and Snow
Remember the extra goggles today. Expect stormy weather in the mountains, with periods of heavy snow, rising avalanche danger, and dangerous conditions already on many steep slopes. You'll find nice deepening powder riding conditions in the meadows and on safe slopes less than 30° in slope steepness.
The Tony Grove Snotel at 8400 feet reports 8 inches of new snow overnight containing 1.2 inches of SWE (snow water equivalent). It's 28° F, with 96 inches of total snow. There's also 8 inches of new snow at the Card Canyon weather station at 8800 feet. It's 25° F, and there's 70 inches of total snow.
At 9700 feet at CSI's Logan Peak Wx station, winds are blowing 18 to 24 mph with overnight gusts to 42 mph from the south and it's 19° F. On Paris Peak at 9500 feet, it's 21° F, with light winds blowing 4 to 8 mph from the south-southeast. (the wind sensor may be snow covered or rimed)
The National Weather Service continued a Winter Storm Warning through Friday evening. It will snow today, and the snow could fall heavily at times with 4 to 8 inches of accumulation possible. Expect a high temperature of 33° F at 8500 feet and 9 to 13 mph winds blowing from the south-southwest.
Snowfall will continue tonight with 3 to 5 inches of accumulation possible. Winds will blow 9 to 11 mph from the west and the temperature will drop to around 20° F. Snow will taper off on Friday, with 1 to 3 inches possible. High temperatures around 28° F and 8 to 14 mph winds from the west-northwest are expected.
Bluebird conditions with plenty of sun and warming temperatures are expected this weekend.

Recent Avalanches
No new avalanches were reported from the Logan Zone recently. Plenty of wet loose avalanches were visible over the past week, and the last reported large natural slab avalanche occurred on February 25.

Avalanche Problem #1
New Snow
Type
Location
Likelihood
Size
Description
Natural avalanches are possible, and people are likely to trigger loose and soft slab avalanches of storm snow up to 2 feet deep on drifted mid and upper-elevation slopes steeper than 30°.
Avalanches of storm snow are also possible in steep low-elevation terrain, but many slopes were bare of snow or had only very shallow coverage before the storm. The rain-snow line descended to the valley floor overnight, but plenty of rain fell on lingering low elevation snow before then.
Avalanche Problem #2
Persistent Weak Layer
Type
Location
Likelihood
Size
Description
While unlikely, the new load may reawaken a persistent weak layer buried 3 to 4 feet deep, and dangerous hard slab avalanches are possible, especially in outlying rocky terrain with generally shallow snow cover. The last reported avalanches failing on this PWL occurred on January 25 and were triggered by cornice falls.
It's a good idea to stick to terrain with deep snow and slopes that are not threatened by overhanging cornices, but the best way to avoid any chance of triggering a dangerous avalanche is to avoid being on or under slopes steeper than 30°.
