Rising sea levels, more intense storms and heavier downpours related to climate change are contributing to increasingly severe and damaging floods. Coastal storms are likely to cause flooding over larger areas and prompt currently at-risk areas to flood more frequently. Heavier downpours can overwhelm existing infrastructure, causing flooding and impacting water quality. Low lying coastal areas are likely to experience more frequent tidal flooding. Understanding flood risks in advance of storms and over the longer term can help decision-makers prepare for the flood-related impacts of climate change.
