UDOT PLANNED AVALANCHE CLOSURES!!

Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Tuesday morning, April 1, 2025
The avalanche danger is MODERATE. Heightened avalanche conditions exist on drifted slopes at upper and mid-elevations, and periods of heavy snow and winds from the west could further elevate the threat today. People could trigger soft slab avalanches of storm snow or stiffer wind slabs, 1 to 2 feet deep, on slopes steeper than 30 degrees.
  • Evaluate snow and terrain carefully.
  • Pay attention to obvious signs of instability like cracking or recent avalanches nearby.
  • Avoid cornices and steep drifted slopes above trees or other terrain traps.

Weather and Snow
The National Weather Service continued a Winter Weather Advisory for the Logan Zone through this evening. 5 to 9 inches could accumulate in upper elevation terrain, and winds from the west will continue to drift snow in the mountains through tonight. The storm is elevating avalanche conditions in the backcountry, with human-triggered avalanches of wind-drifted storm snow possible at upper and mid elevations today. We'll find nice shallow powder riding in the new snow today, especially in low-angled terrain where the underlying crusty old snow from last week is smooth. The snowpack took quite a hit from last week's hot weather, with most low-elevation terrain completely melted off or with very shallow coverage.

The Tony Grove Snotel at 8400 feet reported around 3 inches of new snow overnight and .8" SWE in the last 24 hours. It's 21° F, with 95 inches of total snow. About 4 inches accumulated at the Card Canyon weather station at 8800 feet. It's 18° F and there is 75 inches of total snow.
At 9700 feet at CSI's Logan Peak Wx station, winds are blowing from the west-northwest 18 to 30 mph, and it's 15° F. The winds on Paris Peak at 9500 feet are blowing from the northwest 15 to 25 mph, and it's 14° F.

It is snowing heavily at Beaver Mountain, and there is about 6" of new snow on their snowstake. (Check the Beaver Mt Webcams) Snow showers are likely today, and snowfall could be heavy at times, with 5 to 9 inches of accumulation possible by evening. Expect a high temperature at 9000 feet around 26° F, and it will be breezy, with a west wind 10 to 18 mph with gusts as high as 32 mph.
Snow showers are possible tonight. Low temperatures will be around 14° F with west-northwest winds decreasing to 6 to 11 mph after midnight.
There's a chance of snow showers tomorrow, mainly after noon. it will be partly sunny, with a high near 30° F. Winds will blow from the west 5 to 10 mph.

Recent Avalanches
No avalanches were reported over the weekend, though last week we observed many wet avalanches due to the heat.

Avalanche Problem #1
Wind Drifted Snow
Type
Location
Likelihood
Size
Description
Human-triggered avalanches of wind-drifted storm snow are possible and will become more likely this afternoon as fresh snow is rapidly drifted onto slopes along ridgelines and in and around terrain features like cliff bands, gully walls, and sub-ridges.
  • Cracking is a sure sign of instability.
  • Avoid being on or underneath overhanging cornices, as they can break back much further than expected and could trigger avalanches on slopes below.
Avalanche Problem #2
New Snow
Type
Location
Likelihood
Size
Description
​​​​​​No Joke! Small loose and soft slab avalanches of storm snow are possible, especially during periods of particularly heavy snowfall. Shallow wet avalanches entraining the new snow are possible on steep slopes if the sun pokes out even for a short period.
Pay attention to potential terrain traps below you, like trees, cliffs, or gullies, that a small avalanche might carry you into.
Additional Information
There were a few good-sized wet slab avalanches spawned by the heat last week, including these in Rattlesnake Canyon in the Wellsville Mt Wilderness. These natural avalanches were triggered by cornice fall. The picture is from Saturday, March 29
