According to a new analysis, U.S. Geological Survey stream gauges in the Carolinas recorded many instances of record-setting water levels during Hurricane Florence in September, with the majority of those eclipsing previous historic peaks set just two years prior during Hurricane Matthew.
Scientists reviewed 485 USGS stream gauges in the Carolinas and focused on 84 that have registered data for at least a decade—with some sites in continuous operation for more than 70 years.
