Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Thursday morning, April 10, 2025
The avalanche danger is MODERATE. After a warm night in the mountains and a poor overnight refreeze, today's intense April sun and seasonal warmth will elevate the threat of wet avalanches on slopes steeper than 30 degrees. Although more likely in sunny terrain, heightened avalanche conditions may exist on any slope with saturated snow. Natural and human-triggered cornice falls, loose wet, and wet slab avalanches are all possible in today's heat.
  • Stay off of and well away from large, overhanging cornices, as they can break back much further than expected.
  • Avoid being on steep slopes with saturated snow, especially those above trees or other terrain traps.

Weather and Snow
Mountain temperatures stayed several degrees above freezing last night, and the winds diminished significantly. With mostly clear skies, yesterday's moist snow surface most likely froze and shallowly hardened. Sunny skies, light winds, and temperatures around 10 degrees warmer than yesterday's are expected today, and any overnight superficial surface refreeze will not last long.
You may start sinking into saturated snow earlier today than yesterday, and if you do, it's time to reevaluate your plans if they include travel in steep avalanche terrain. Now is not a good time for challenging mountaineering, peak bagging, or extreme skiing-gully surfing. You'll find decent riding conditions with plenty of wet snow to cool your sled in lower-angled terrain and in the high meadows, but watch for weakened snow bridges and tank traps around steams that are melting out. Plan on a significant warm-up today and tomorrow, with daytime temperatures pushing 60° F at the highest elevations in the Bear River Range.
The snow has completely melted off most low-elevation slopes in the Logan Zone (below about 7000 feet). The little that remains in north-facing terrain is very shallow and patchy.
The Tony Grove Snotel at 8400 feet reports 40° F this morning, with 86 inches of total snow. It's already 40° F at the Card Canyon weather station at 8800 feet, with 65 inches of total snow. At 9700 feet at CSI's Logan Peak Wx station, winds are blowing from the west-northwest 8 to 15 mph, and it's 38° F. The winds on Paris Peak at 9500 feet are blowing from the west-northwest at 10 to 15 mph, and it's 37° F.
Today will be sunny, with high temperatures at 9000 feet near 58° F (around 10 degrees warmer than yesterday's high). Light winds blowing out of the south-southwest are expected this afternoon. Tonight will be partly cloudy, with a low temperature around 38° F. Winds will blow from the south-southwest 8 to 10 mph. Tomorrow will be mostly sunny, with a high temperature near 62° F. Winds from the southwest will blow 8 to 16 mph. Dangerous wet avalanche conditions may develop with tomorrow's heat, but a cool-down is expected for the weekend, with clouds and showers possible on Saturday and temperatures dropping to around 21° F on Saturday night.

Recent Avalanches
No avalanches were reported recently in the Logan Zone, but I could see some small recent natural cornice falls and loose wet avalanches in the Wellsvilles from western Cache Valley yesterday.

Description
Today's warm temperatures will increase the danger of wet avalanches. The poor overnight refreeze may cause the snow to soften up earlier in the day today than it did yesterday. As the snow melts and becomes waterlogged and loose, wet avalanches will become possible on steep slopes. Roller balls and pinwheels are sure signs of instability.
  • Pay attention to potential terrain traps below you, like trees, cliffs, or gullies, that a small avalanche might carry you into.
  • Avoid being under steep slopes with saturated snow.
  • If you are sinking in above your ankles, move to a cooler aspect, elevation, or lower-angle terrain.
Avoid being on or underneath overhanging cornices, as they can break back much further than expected and could trigger avalanches on slopes below. The warm temperatures make them more fragile.
These natural wet avalanches in Rattlesnake Canyon in the Wellsville Mt Wilderness occurred during our most recent warm spell at the end of March. After a few warm nights and mountain daytime temperatures in the 50s, cornice falls spawned by the heat, triggered wet slab avalanches.
Additional Information
Our regular daily avalanche forecasts will end this Sunday, April 13. After that, we will issue updates when necessary and publish public observations until May 1.
