Below is the North American Public Avalanche Danger Scale, which offers explanations of the danger levels and what each means. These are the ratings you will find on avalanche advisories. As well, many advisories will use the avalanche danger rose.
- National Ski Patrol (NSP) Southern California: Offer Level I and II courses in So Cal. Also work with partner instructors in the Sierra.
- Sierra Mountain Guides (SMG): A great resource for AVI 1 and 2 courses in the Sierra.
- Sierra Mountain Center (SMC): Another guide service in the Sierra offering avalanche courses.
- Sierra Mountaineering International (SMI): And one more...
Nearby (relatively speaking) Avalanche Centers
- Eastern Sierra Avalanche Center (ESAC): The one and only avalanche forecasting center in the Eastern Sierra.
- Sierra Avalanche Center (SAC): Avalanche forecasting for the Tahoe area. Great resource for up-to-date snowpack reports. We hope that one day So Cal Snow's reports page will look like theirs!
- Mt. Shasta Avalanche Center
- Kachina Peaks Avalanche Center (Arizona)
- Central Oregon Avalanche Association: This group is similar to So Cal Snow, as they do not produce official advisories, but instead promote awareness and user-submitted field reports.
