Forecast for the Logan Area Mountains

Friday morning, February 14, 2025
The avalanche danger will rise to HIGH in the backcountry today. Heavy snowfall and drifting by strong winds from the southwest will continue to elevate the danger. Natural and human-triggered avalanches are increasingly likely on slopes steeper than 30° at all elevations.
People should avoid travel in all avalanche terrain and stay clear of avalanche runouts.

Avalanche Warning
  • The avalanche danger is HIGH today and may rise to EXTREME in some areas this weekend.
  • Very dangerous avalanche conditions are expected through the weekend.
  • Heavy snow and drifting by strong winds have created widespread areas of unstable snow and very dangerous avalanche conditions at all elevations. Natural and human-triggered avalanches are likely.
  • People should avoid travel in all avalanche terrain and keep out of avalanche runouts. This means you should stay off of and out from under slopes steeper than 30 degrees.
Weather and Snow
The avalanche danger will continue to rise today as a powerful winter storm, an "inland penetrating atmospheric river event" impacts the Logan Zone. Drifting by strong and sustained winds from the southwest and heavy snowfall will rapidly create very dangerous avalanche conditions. The danger will rise to HIGH during the day today. Significant natural avalanche activity is quite possible, so people should stay well clear of avalanche runouts.
Heavy storm snow and drifting snow are overloading a widespread weak layer of near surface facets and graupel capping a very hard melt/freeze crust in most areas. This is particularly a concern on snow-covered slopes at lower and mid elevations, where the recrystallized snow on the dusty crust is shallow. The hard crust will likely be a slick bed surface for many avalanches this weekend.

-The Tony Grove Snotel at 8400 feet reports 9 inches of new snow with 1.3" SWE in the last 24 hours. It's 27° F, with 79 inches of total snow. The Card Canyon weather station at 8800 feet reports 5 inches of new snow. It's 24° F, and there is 58 inches of total snow.
-Winds from the south were quite strong and sustained all day yesterday at the CSI Logan Peak weather station at 9700 feet. Overnight they began to swing around from the west, and are now blowing from the west-southwest 24 to 35 mph with overnight gusts of 65 mph. It's 22° F. On Paris Peak, at 9500 feet, it is 21° F, and the winds are blowing 18 to 25 mph from the southwest, with overnight gusts around 35 mph.

The National Weather Service has continued a Winter Storm Warning through Saturday evening. The Logan Area Mountains could pick up a couple more feet of snow. Snowfall will be heavy at times today, with 8 to 12 inches of accumulation possible. Expect a high temperature at 8500 feet around 30° F, with winds blowing from the west-southwest around 15 mph. Snow will be heavy at times tonight, with 6 to 10 inches of additional accumulation possible. The temperature will drop to around 17° F, and winds from the west will blow 9 to 13 mph. Tomorrow, steady temperatures will stay just below 20° F, winds will blow 15 to 20 mph with gusts in the 30s from the west, and 2 to 4 inches of snow is possible.
Please read our forecasts before heading out into the backcountry - we've had four avalanche fatalities this season and do not want another.

Description
AVOID TRAVEL IN ALL AVALANCHE TERRAIN AND STAY CLEAR OF AVALANCHE RUNOUTS
  • Soft slab and loose avalanches of storm snow will become increasingly likely on steep slopes at all elevations as heavy snow accumulates in the backcountry. People are very likely to trigger avalanches on slopes steeper than about 30°, and avalanches could be triggered remotely (from a distance) or from below steep slopes. Large and long-running natural avalanches will probably occur in many areas today and/or tonight, so people should stay well clear of avalanche runouts.
  • Wind slab avalanches, consisting of drifted storm snow, are likely in wind exposed terrain at all elevations. Natural cornice falls and large wind slab avalanches will be increasingly likely as strong winds from the west-southwest load tremendous amounts of fresh snow into avalanche starting zones. Wind slabs are most likely found on the lee side of major ridges and corniced slopes facing northwest through southeast, but also in and around terrain features like sub-ridges, gullies, scoops, and cliff bands.
  • Large and dangerous avalanches stepping down into older snow on one of several buried persistent weak layers are also likely, especially in areas with shallow snow and poor snow structure. Audible collapses (whumpfs) and shooting cracks are sure signs of instability, but these may not be present when avalanches occur. Avalanches failing on a buried persistent weak layer might be triggered remotely (from a distance) or from below steep slopes.
