Forecast for the Logan Area Mountains

Paige Pagnucco
Issued by Paige Pagnucco on
Saturday morning, March 15, 2025
Avalanche conditions are heightened in the backcountry. Triggering wind-drifted avalanches on upper and mid-elevation slopes steeper than 30 degrees is possible. Some areas may reach CONSIDERABLE danger, especially on northwest to southeast-facing slopes, with wind slabs building up to 1-2 feet deep. Avalanche danger will increase throughout the day with periods of heavy snowfall and strong winds.
Make conservative choices, evaluate snow and terrain carefully, and avoid steep, drifted slopes and overhanging cornices.
You'll find improving riding conditions with the best riding in low-angle terrain as the day progresses.

Weather and Snow
Thursday's storm left an even coating of about 3-5" of snow across the zone, improving riding conditions slightly. Today's more robust storm should help with another 6 - 10 inches of snow forecast. The hard melt-freeze crust is slowly getting buried, and hopefully, by this afternoon, we'll be hearing a lot less scratching under our skis. Today's biggest concern is wind-drifted snow in exposed terrain as winds are expected to be fairly obnoxious in the afternoon, with consistent speeds in the teens mph and gusts near 40 mph. We may also see new snow and dry loose avalanches in steep terrain as the snow accumulates. You'll find the best riding conditions on lower-angle slopes facing any direction where you can avoid hitting the hard crust.
The Tony Grove Snotel at 8400 feet reports 3 inches of new snow in the past 24 hours. It's 20° F, with 95 inches of total snow. It's 16° F at the Card Canyon weather station with 3 inches of new snow and 74 inches of total snow. At 9700 feet at CSI's Logan Peak Wx station, winds are blowing 20 to 36 mph from the northwest, and it's 13° F. The winds on Paris Peak at 9500 feet are blowing 10 to 19 mph from the west-southwest.
Winter is back! The National Weather Service has issued a Winter Weather Advisory for today. It's already snowing in the mountains, but it should really turn on this afternoon with gusty winds and periods of heavy snowfall. 8500' high temps will be around 25°F but may feel much colder, with winds blowing from the west at 16-21 mph and gusts up to 40 mph. Snowfall continues through tomorrow, with another 4-8" of accumulation possible by Sunday evening. Unfortunately, the winds will stick around, and we expect a significant temperature bump tomorrow. Another storm is on tap for Monday night.

Recent Avalanches
  • We are very sad to report a fatal avalanche accident that occurred on Friday, March 7, in the Western Uinta Mountains near Kamas. The preliminary accident report is HERE.
  • No avalanches were reported yesterday.

Avalanche Problem #1
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
Winds are the big story today. They are expected to blow fairly consistently from the west, around 15-20 mph, with gusts near 40 mph. There'll be plenty of fresh snow to blow around, especially this afternoon when snowfall really kicks in. Hard and soft wind slabs will develop on the lee side of exposed ridges and around terrain features like cliff bands, sub-ridges, and gullies.
  • Watch for and avoid stiffer wind drifted snow on the lee side of major ridges, below cornices, and in and around terrain features like cliff bands, sub-ridges, and gully walls.
  • Wind slabs appear smooth, chalky, and rounded, and they can sound hollow, like a drum, when you move around on them.
  • Cracking is a red flag indicating unstable snow.
  • Hard wind slabs sometimes let you get out on them before releasing suddenly. Freshly formed, softer wind slabs are often very easily triggered, sometimes remotely (or from a distance).
  • 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. Natural cornice falls are possible, and these could trigger avalanches on slopes beneath.
Avalanche Problem #2
New Snow
Type
Location
Likelihood
Size
Description
Small storm slabs and dry loose avalanches of new snow are possible on steep slopes, especially during periods of high PI. Some of these could run pretty fast and far on the just barely covered melt-freeze crust. Small avalanches of new snow are generally manageable, unless you are caught and carried into trees or other terrain traps below steep slopes. As snow accumulates and gets deeper, these may become unmanageable. Again, the best riding conditions will be on slopes less than 30 degrees to mainly avoid hitting the shallowly buried melt-freeze crust.
