The North American Avalanche Danger Scale is a five level scale used to communicate the danger of avalanche to backcountry recreationalists. The danger is a combination of the expected likelihood, size, and distribution of avalanches. It provides a very basic description of the avalanche conditions.

Are you a member of the Northwest Avalanche Center, or have you renewed your membership for the 2014-15 winter?
Donations from individuals in the community are critical to the continued success of NWAC. Your 2014-15 membership will help ensure that we can forecast reliably until the snow stops falling in the spring, enable repairs and improvements to weather stations and the website, and allow us to provide free avalanche awareness classes to those who need it most. Your support will also help us develop a new NWAC mobile app and hire two more professional observers to make the avalanche forecast even more accurate!
Please consider supporting a service that may someday save your life or that of someone close to you.
