Advisory Area

The Sawtooth Avalanche Center advisory provides danger roses, danger ratings, and a Bottom Line for different zones within the advisory area. This map shows the different zones, along with locations of the five weather stations we or our partners operate. Keep in mind:

  • The advisory 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 advisory applies, but expect variations in conditions and danger levels.
