Avalanche Danger Scale

The Canadian Avalanche Danger Scale is consistent with the five level international danger scale used in alpine nations world-wide. The danger scale as used by the CAC is intended for public recreation advice in uncontrolled backcountry areas.

Backcountry Avalanche Advisory (BAA)

The BAA offers a simplified view of avalanche conditions for awareness purposes. BAA levels are related to, but not exactly the same as avalanche danger. BAA advice and guidance offers information on how prepared users need to be to undertake activities in the backcountry on a given day. Only one BAA icon is supplied per forecast region. This icon is updated daily during the avalanche season.
