Forecast for the Logan Area Mountains

Toby Weed
Issued by Toby Weed on
Tuesday morning, March 25, 2025
Warm temperatures and strong sun will elevate wet avalanche conditions at all elevations today. The danger is MODERATE; large cornice falls and shallow wind slab avalanches are possible in upper-elevation terrain. As temperatures rapidly warm during the day, natural wet avalanches are possible, and people could trigger wet loose or wet slab avalanches on steep slopes with saturated snow.
Evaluate the snow and terrain carefully.
  • Avoid overhanging cornices as they could break further back than expected and could cause an avalanche on the slope below.
  • 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.

Special Announcements
Our Spring Campaign is in full swing, and there are two great ways to support forecasting, awareness, and education across Utah:
Every dollar helps keep the backcountry community on top. Thank you for your support!
Weather and Snow
Very warm mountain temperatures and blow-dryer winds are doing in the low-elevation snow. Many solar slopes at low and mid elevations have already burnt off, and you have to travel over rocks and mud to access the snow from many of our lower trailheads. It was nice to get out into the backcountry yesterday, but the warming temperatures rapidly turned the surface snow to slush. We expect mountain temperatures to be several degrees warmer today, with less clouds and more periods of direct sun. After another night with above-freezing temperatures and a poor surface refreeze, the danger of wet avalanches will rise rapidly with the temperatures today. Small avalanches of wind-drifted snow and large cornice falls are possible up high in exposed terrain, mainly on slopes facing northwest through southeast. Expect an uptick in mountain temperatures tomorrow and again on Thursday, with a high of 60° F possible at the summit of Naomi Peak.
The Tony Grove Snotel at 8400 feet reports 98 inches of total snow. It's too warm; 38°F this morning, and temperatures stayed a few degrees above freezing overnight. It's 34° F at the Card Canyon weather station at 8800 feet, with 75 inches of total snow.
At 9700 feet at CSI's Logan Peak Wx station, winds are blowing 20 to 25 mph from the northwest, and it's 31° F. The winds on Paris Peak at 9500 feet are blowing 17 to 21 mph from the west-southwest, and it's also 31° F.
Today will be sunny with a high temperature at 8500 feet near 51° F. Winds will blow from the northwest around 7 mph. Skies will be mostly clear tonight, with low temperatures around 32° F and wind blowing from the south-southwest 6 to 10 mph. Tomorrow will be sunny, with a high temperature around 55° F and 8 to 11 mph winds switching around from the east.
Significant warming is expected to continue, as mountain temperatures could top 60° F on Thursday We can expect significant melting and continuing burnoff of sunny slopes at low and mid-elevations.
The next chance for snow (or rain) showers comes late Thursday and Friday. Snow showers are also expected in the mountains over the weekend.

Avalanche Problem #1
Wet Snow
Type
Location
Likelihood
Size
Description
Daytime warming and sunshine will cause the snow on solar slopes to become unstable. Natural wet loose and slab avalanches will become increasingly likely as temperatures rise significantly this week.
  • Watch for rollerballs and pinwheels 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 simply to lower-angle terrain.
  • 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.
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.
  • With daytime heating, natural and human-triggered cornice falls are possible today, and these could trigger avalanches on slopes beneath.
  • Stiff slabs of wind-drifted snow exist in some areas, mainly near ridgelines and in 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 and below cornices. Hard wind slabs sometimes let you get out on them before releasing suddenly.
