USGS Flood Information

Current Flood Events | Hurricane Sandy | Mapper

Prior to the arrival of Hurricane Sandy, USGS technicians deployed non-transmitting storm tide sensors and wave height sensors and real-time rapid deployment streamgages (RDGs) along the Northeast coast.

The data are available on the Hurricane Sandy Mapping Application. The mapper provides location information, site photos and data for storm tide and inland flooding. Data will be made available as soon as possible following the storm.

Please read this critical user information.
