The Impacts theme focuses on the multi-faceted nature of hurricane hazards (winds, storm surge, waves, heavy rainfall, flooding, mudslides) continues to result in natural disasters with loss of life and property. Substantial improvements are needed to develop and validate impact-relevant metrics from numerical weather forecast and stochastic risk model outputs, so people can be advised on the potential consequences of a hurricane event. HRD scientists are involved in research to advance the understanding of these impacts. We have partnerships within our agency, with other government agencies, academia and the private sector that are part of the preparedness, response and recovery during extreme events.
