Forecast for the Logan Area Mountains

Nikki Champion
Issued by Nikki Champion on
Wednesday morning, December 31, 2025

This morning, the avalanche danger is LOW. The persistent weak layer problem still exists in isolated, steep, upper-elevation northerly terrain, though it is now unlikely to trigger. This is a low-probability, high-consequence setup.

Avoid thinner areas where buried objects may be lurking just beneath the snow surface. LOW danger doesn’t mean no danger. Continue moving through terrain with safe travel techniques and stay tuned to changes in the snow and weather.

Keep an eye on the snow surface. If it becomes damp and unsupportable, and you start seeing pinwheels or roller balls, it may be time to switch aspects.

Weather and Snow

This morning, it’s 37°F at Tony Grove with 40 inches of total snow. At the UAC Card Canyon weather station, the temperature is 35°F with 25 inches of total snow. Winds on Logan Peak are blowing from the west at around 15 mph, with gusts reaching 25 mph. On Paris Peak, it’s 35°F with winds from the west southwest at 20 to 25 mph.

Today will be another beautiful, sunny day in the mountains. Temperatures will climb into the mid to upper 30s°F at 8,500 feet with light winds from the west. Forecast models suggest snowfall returning this weekend, beginning the morning of the first of the year.

Riders continue to report excellent conditions, with fresh snow and colder temperatures finally delivering winterlike riding. The recent storm snow is bonding well to the old, damp surface, and the instabilities from the last storm cycle have mostly settled out. Shaded aspects should still hold cold snow this morning. Yesterday, solar aspects picked up a bit of heat, so those slopes will likely have a crust on them today.

Recent Avalanches

No new avalanches have been reported locally since early December. Yesterday was generally quiet in the backcountry, with no new signs of instability observed or reported.

Description

Our main concern is still the poor snowpack structure, with November facets lingering near the ground. In many areas, those grains are now moist or wet, and overall, they’re showing fewer signs of instability.

Hard slab avalanches up to 3 feet deep are still possible in isolated, steep, upper elevation terrain with wind-loaded snow, but the likelihood of triggering has dropped to unlikely. If you see collapsing, shooting cracks, or hear a whumpf, take it seriously. Step into steeper terrain cautiously. LOW avalanche danger doesn’t mean zero danger.

Additional Information

Use safe travel practices: travel with a partner, and cross or ride steep slopes one at a time while the rest of your group watches from a safe spot.
