GNFAC Avalanche Forecast for Sun Jan 29, 2023

Good morning. This is Alex Marienthal with the Gallatin National Forest Avalanche Forecast on Sunday, January 29th at 7:15 a.m. Today’s forecast is sponsored by Stronghold Fabrication, Gallatin Valley Snowmobile Association and Pine Edge Cabins. This forecast does not apply to operating ski areas.

Mountain Weather

This morning, there is no new snow, temperatures are negative teens to negative 20s F, and wind is 0-10 mph with gusts of 15-20 mph out of the east-northeast. Today will be partly cloudy with temperatures 5-15 degrees below zero F and northerly wind at 5-15 mph. A few snowflakes may fall the next couple days, but the next chance for significant snow is Tuesday.

Snowpack and Avalanche Discussion

All Regions

Recent heavy snowfall has created dangerous avalanche conditions and human triggered avalanches are likely. The mountains near Bozeman and Big Sky received 2-4 feet of snow since Wednesday (2-4” of snow water equivalent), and an avalanche warning was issued on the last two days. The warning expired today, but the snowpack is still unstable with a variety of buried weak layers. Over the last two days, people reported many large natural and human-triggered avalanches: 

Near West Yellowstone and Cooke City, 1-3 feet of new snow (1-2” of snow water equivalent) did not cause an avalanche warning, but created similarly dangerous conditions as shown by reports of many large natural avalanches:

  • Skiers and riders near Cooke City saw large slides near Daisy Pass (photos) and up Republic Creek (photos and details).
  • Yesterday Doug and I looked at a fresh avalanche in Taylor Fork which broke on weak facets and surface hoar up to 2.5’ deep and 750’ wide (video, details and photos), and we saw many natural avalanches that broke 1-2’ deep in the new snow. 

Similar avalanches can be triggered today, would have large consequences, and can be triggered on steep slopes or from lower angle terrain below steep slopes. Until the snowpack has adjusted to this recent storm, your safest plan is to avoid travel in avalanche terrain. Today, large human-triggered avalanches are likely and avalanche danger is CONSIDERABLE.
