Abstract

Understanding the spatial variability in the hydrological impact of landfalling tropical cyclones (TCs) is critical for current and future risk management of floods/droughts that occur at relatively local to watershed scale. In this context, this study examines the role of TCs in flooding and drought mitigation, from a climatological perspective, through analyzing the long-term, spatially distributed observational datasets of hurricane tracks, precipitation, and streamflows over the Mid-Atlantic region. Despite limited contribution of TCs to annual precipitation (
