Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Friday morning, March 28, 2025
The avalanche danger is MODERATE; wet avalanches and large cornice falls are possible on steep slopes with saturated snow.
Evaluate snow and terrain carefully. Avoid and stay out from under overhanging cornices as they could break further back than expected and could cause avalanches on slopes below.

Weather and Snow
A couple of inches of new snow accumulated early this morning at upper elevations across the Bear River Range, and we expect improved riding conditions today. Temperatures dropped into the mid-twenties on the mountain tops overnight, and they reached freezing early this morning at the Tony Grove Snotel. Yesterday, we found decent riding in the Egan Basin area and observed stable snow conditions in upper-elevation north-facing terrain. Beaver Creek is starting to melt out, adding a tank trap hazard to the list of concerns. With only a light refreeze overnight, warming daytime temperatures will elevate the wet avalanche danger on steep slopes with saturated snow today despite a breeze and cloudy skies. Natural cornice falls are possible near major ridgetops, and these could trigger large wet avalanches on slopes beneath.
Beaver Creek and other mountain streams are melting out and opening up, creating another springtime backcountry hazard to keep in mind.
*** Spring Travel Advice: The danger of wet avalanches will rise with the temperatures, so get an early start and finish the day early. If you start sinking into saturated snow, it's time to pull the plug, reevaluate your route, or change your location.
The Tony Grove Snotel at 8400 feet reports 2 inches of new snow early this morning, and there is 93 inches of total snow. It's pretty warm again; 32° F this morning, and temperatures stayed well above freezing for most of the night. Temperatures dropped to 26° F overnight at the Card Canyon weather station at 8800 feet. There is 2 inches of new snow, with 69 inches of total snow.
At 9700 feet at CSI's Logan Peak Wx station, winds are currently blowing 18 to 23 mph from the northwest, and it's a cool 23° F. The winds on Paris Peak at 9500 feet are blowing 16 to 22 mph from the west-northwest, and it's also 23° F.
Today will be mostly cloudy with a high temperature at 9000 feet near 41° F. Winds will blow from the southwest 6 to 14 mph. Skies will be mostly cloudy tonight, with low temperatures around 26° F and 6 to 12 mph winds switching from the north. Snow is likely tomorrow, mainly after noon. The snow could be heavy at times, with 3 to 7 inches of accumulation possible. High temperatures at 9000 feet will be near 37° F, and winds from the southeast will blow 6 to 14 mph and veer from the west in the afternoon. Mountain temperatures will drop to around 20° F on Saturday night, with a couple more inches of snow possible.
The weather will remain unstable through next week, with cooler temperatures and periods of mountain snow.

Recent Avalanches
Tuesday, I saw a recent natural slab avalanche in Pine Canyon in the Wellsville Mt Wilderness. From a distance, I estimated the avalanche at around 8800 feet on an ENE-facing slope to be about 3 feet deep and 250 feet wide. Picture Window Ax report
Numerous natural wet loose avalanches and roller-ball swarms from the past few days are visible from Cache Valley, and the mountains look like they are dripping hot candle wax.

Avalanche Problem #1
Wet Snow
Type
Location
Likelihood
Size
Description
Daytime warming will cause the saturated snow to become unstable on some steep slopes. Wet loose and slab avalanches are possible as temperatures rise during the day.
  • Watch for rollerballs, pinwheels, and sluffs, as signs of instability.
  • If you sink up to your ankles in the mushy snow, it is time to move to a cooler aspect or elevation or to lower-angle terrain.
  • Avoid travel on steep slopes above trees or other terrain traps.
Avalanche Problem #2
Cornice
Type
Location
Likelihood
Size
Description
  • People should stay off of, out from under, and well away from the edges of large overhanging cornices, which are deceptive and often break much further back than expected.
  • Stay out from under the large cornices, as the heat will cause them to buckle and some to calve off large, school bus-sized chunks. With daytime heating, natural and human-triggered cornice falls are possible, and these could trigger avalanches on slopes beneath.
