This document outlines a new approach to defining the impact of weather. By examining the factors that produce the weather's impact, whether it is the characteristics of the event itself, who/what is being impacted, and the capacity to mitigate the impact, this document outlines a broader range of impact types. These are:
Low-impact minor inconvenience, small and local economic losses, etc. Moderate-impact minor damage, some social disruption, etc. High-impact damage, risks to health, broad economic impact, etc. Extreme-impact Catastrophic losses, deaths, injuries, major social disruption
The impact of weather is applied to economic sectors, people, society, and the environment to determine the characteristics of each category. This approach also suggests a tiered method of alerting the end user to the various levels of weather impact. This is discussed briefly in the presentation.
