Expanding the concept of avalanche climate: Detailed insights into the nature and variability of avalanche hazard in Western Canada between 2009/10 and 2016/17

Different snowpack structures and weather conditions create distinct types of avalanche problems that require different risk mitigation practices. In North America, nine types of avalanche problems have been identified in the recently introduced Conceptual Model of Avalanche Hazard (CMAH). Avalanche Canada and Parks Canada forecasters have identified and assessed avalanche problems according to the CMAH daily since the winter 2009/10. This dataset provides a unique opportunity for examining the nature of avalanche hazard in western Canada.
