2026 Early Season Avalanche Statement

When it comes to early-season avalanches, the bottom line is simple: if there’s enough snow to ride, there’s enough snow to slide. Whether you’re out hiking, hunting, searching for some early-season turns, or breaking out the snowmobile, don’t let the date on the calendar fool you. Avalanche accidents and fatalities have occurred this time of year.  

Limited information makes it tricky to determine when and where you might trigger an avalanche. Often, the same places we seek out for early-season fun are the exact locations where avalanches are more likely:

  • High elevation terrain
  • Permanent snowfields
  • Wind drifted slopes

Be cautious in terrain where snow hides vegetation and rocks. As snow depth increases, so could the size of avalanches. You’re most likely to encounter unstable snow:

  • During and immediately after a storm
  • In steep, wind-loaded terrain

Even though the amount of snow on the ground may limit the size of an avalanche, terrain traps can cause even tiny slides to result in serious injury or death. Avalanche fatalities have occurred from a victim being: 

If your plans include traveling through or within a closed ski resort: 

  • Check the ski area’s uphill travel policy. 
  • The snowpack and terrain at a closed ski area may pose hazards similar to those found in any backcountry location. 
  • Be prepared to make your own assessments, choose appropriate terrain, and handle any emergency situation that may arise.

If you’re out in the mountains, please take a moment to submit an observation. Simply a photo showing terrain with snow cover and information on snow depths is very helpful.

NWAC is actively preparing for winter. Avalanche and mountain weather forecasts typically begin in mid to late November as the winter snowpack develops. In the meantime, check over your gear, refresh on your snow and avalanche training, and get excited about the winter to come!
