Avalanche.org connects the public to formal avalanche information and education in the United States. Avalanche.org is a partnership between the American Avalanche Association (A3) and the US Forest Service National Avalanche Center (NAC).

The U.S. and Canada use a five-category estimation of the avalanche danger: low, moderate, considerable, high, and extreme. The North American Avalanche Danger Scale is a tool used by avalanche forecasters to communicate the potential for avalanches to cause harm or injury to backcountry travelers. This video provides an overview of the scale, as well as a quick illustration of how it applies to your daily backcountry risk assessment. More information here.
