Forecast Area

The Sawtooth Avalanche Center forecast provides a Bottom Line, Danger Ratings, Avalanche Problem discussions, and Weather Forecast for 4 different zones within the forecast area. Keep in mind:

  • The forecast regions are approximate.
  • When you are traveling near the boundaries of two zones, factor the information and Danger Rating from both zones into your decision-making.
  • We receive fewer observations from more remote areas. The avalanche forecast applies, but expect variations in conditions and danger levels.

Listed below are brief descriptions of each zone.
