Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Monday morning, March 10, 2025
The backcountry avalanche danger is MODERATE. Avalanches of wind drifted snow are possible on steep slopes at upper elevations this morning. Warm temperatures in the mountains will elevate the danger during the day, and both human-triggered and natural avalanches of wet snow and large cornice falls are possible under the intense March sun on slopes steeper than 30 degrees.
  • Evaluate snow and terrain carefully, and continue to practice safe travel protocols.
  • Stay off and out from under overhanging cornices; they can break back much farther than expected and can trigger avalanches on slopes below.

Special Announcements
We are very sad to report a fatal avalanche accident that occurred on Friday in the Western Uinta Mountains near Kamas. Preliminary accident report is HERE
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.
Weather and Snow
Winds from the south-southwest increased overnight and continue around 30 mph on the ridge-tops this morning. Drifting likely created small wind slabs on the lee sides of major ridges and in and around upper elevation terrain features. The snow in high shady terrain should still be in decent condition this morning, but we'll find surface crusts of differing thicknesses on most slopes. Once the sun climbs high enough, its sharp March angle will soften the crusts and it could turn the surface of the snow into a pile of unstable mashed potatoes or slush. As the snow becomes saturated, heightened avalanche conditions will develop, with wet avalanches and large cornice falls possible.
Low elevation terrain facing the south half of the compass is bare of snow or has only very shallow snow cover.
The Tony Grove Snotel at 8400 feet reports 33° F, with 94 inches of total snow. It's 31° F at the Card Canyon weather station with 70 inches of total snow. At 9700 feet at CSI's Logan Peak Wx station, winds are blowing 30 to 38 mph from the south-southwest, and it's 26° F. On Paris Peak at 9500 feet, it's 26° F, with winds blowing 22 to 32 mph from the south-southwest.
Expect another stunning day in the mountains with clear skies, strong sunshine, and high temperatures at 8500 feet pushing 40° F. Tomorrow will be the same but a little bit warmer. Sunshine and warm temperatures last through midweek with the next chance for snow beginning on Wednesday night, with another good shot of snow expected in the Logan Zone on Thursday.

Recent Avalanches
-Natural wet avalanches were reported from and observed in sunny terrain across the zone Saturday and yesterday, including in the Wellsville Mt and Mt Naomi Wildernesses and in Logan Canyon.
-We received multiple reports of natural and human-triggered storm slab avalanches Thursday and Friday, ranging from 12-18 inches deep and up to 200 feet wide. These were all on very steep slopes, approaching 40° in slope steepness.

Avalanche Problem #1
Wet Snow
Type
Location
Likelihood
Size
Description
  • Human-triggered soft slab avalanches up to two feet deep and perhaps 200 feet wide are still possible today on steep slopes in drifted mid and upper-elevation terrain where a weak layer above a melt-freeze crust may still exist.
  • Rapid warming today will elevate the danger of both wet loose and wet slab avalanches, especially in sunny terrain and at low elevations. Natural avalanches entraining significant piles of wet snow will become increasingly likely as the fresh snow becomes saturated due to surface melt.
  • If the snow you are in starts feeling sticky or moist, move to cooler aspects or higher elevations, or avoid travel in steep terrain altogether.
**People fishing in the Logan River should avoid being under steep snow-covered slopes, especially in places like the Dugway and the turns just below Temple Fork.
Avalanche Problem #2
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
Drifting by winds blowing from the south-southwest likely created shallow but stiff wind slabs in upper elevation terrain. Watch for and avoid recent drifts on the lee side of major ridges, below cornices, and in and around terrain features like cliff bands, sub-ridges, and gully walls.
  • Cracking is a red flag indicating unstable snow.
  • Wind slabs sometimes let you get out on them before releasing suddenly.
Avalanche Problem #3
Cornice
Type
Location
Likelihood
Size
Description
  • Large natural cornice falls are likely during the heat of the day, and these could trigger slab avalanches of recent drifted storm snow on slopes beneath.
  • People should stay off of, out from under, and well away from large overhanging cornices, which are deceptive and often break much further back than expected.
Additional Information
We come to you with heavy hearts and great sadness this morning to confirm an avalanche accident on Friday, March 7th near Hoyt Peak, involving 51-year-old Micheal Janulaitis from Marion, Utah. Micheal was caught, carried, and killed in an avalanche while skiing a steep, northeast facing run in Hoyt Bowl. Huge thanks to the Department of Public Safety, Park City Mountain Resort and Canyons Village Snow Safety and Ski Patrol teams, along with Wasatch Backcountry Rescue for the hard work recovering Micheal and returning him to his family. Micheal was a friend of Utah Avy and we feel privileged for the time we got to spend together. This is a tremendous loss for our backcountry family and we will miss him deeply. We are compiling accident details and a preliminary report can be found HERE.
