Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Wednesday morning, April 9, 2025
The avalanche danger is LOW this morning. Good ventilation by winds blowing from the west should prevent the snow from getting too soft, but intense April sun and seasonal warmth will elevate the threat of wet avalanches on slopes steeper than 30 degrees. In some sheltered sunny terrain, heightened wet avalanche conditions could develop, and the danger may rise to MODERATE.
  • Use normal caution and follow safe travel protocols, exposing only one person at a time to avalanche risk.
  • 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
High clouds trapped the April warmth in the atmosphere overnight, and mountain temperatures stayed around or above freezing... Mostly sunny skies are expected today, and the overnight superficial surface refreeze will not last long. We may start sinking into saturated snow earlier today than yesterday. Plan on a significant warm-up in the next couple of days, with daytime temperatures pushing 60° F at the highest elevations in the Bear River Range tomorrow and Friday. This will elevate the danger of wet avalanches, especially on Friday if Thursday night's temperatures don't fall below freezing.
The snow has completely melted off most low-elevation slopes in the Logan Zone (below about 7000 feet). What remains in north-facing terrain is very shallow and patchy.
The Tony Grove Snotel at 8400 stopped updating yesterday afternoon, with 89 inches of total snow. It's 35° F at the Card Canyon weather station at 8800 feet with 67 inches of total snow. At 9700 feet at CSI's Logan Peak Wx station, winds are blowing from the west-northwest 15 to 25 mph, and it's 31° F. The winds on Paris Peak at 9500 feet are blowing from the west-northwest at 17 to 30 mph, and it's 31° F.
Today will be mostly sunny, with high temperatures at 9000 feet near 48° F. Winds blowing out of the west will blow 7 to 15 mph with gusts around 30 mph. Tonight will be mostly clear, with a low temperature around 32° F. Winds will blow from the west-southwest 6 to 15 mph. Tomorrow will be mostly sunny, with a high temperature near 58° F. Winds from the east-southeast will blow 7 to 10 mph and switch from the south-southwest in the afternoon. Overnight temperatures at the highest elevations in the Bear River Range will not drop below freezing tomorrow night and will be around 40° F, with Friday's daytime high temperatures around 60° F.

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 gets slushy or sticky, 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
Here is the video from last Wednesday (4-2-25) in the Provo Area Mountains. Don't underestimate the potential of wet avalanches; avoid and stay out from under steep slopes with saturated snow in the heat of the day.
