Short summary
We analyzed long-term groundwater, precipitation, and storm-surge records across coastal New York and Connecticut to estimate how often these hazards occur together. Overlap is highest along southwestern Long Island and western coastal Connecticut during the colder months, when groundwater is higher and mid-latitude cyclones are more common. Results from this study can support better preparation for coastal storms by taking into consideration the compounding effects of different flood drivers.
We analyzed long-term groundwater, precipitation, and storm-surge records across coastal New...
