• Description:
  In this report, we show that water level exceedances above the elevation threshold for “minor” coastal flooding (nuisance level) impacts established locally by the National Weather Service (NWS) have been increasing in time. More importantly, we document that event frequencies are accelerating at many U.S. East and Gulf Coast gauges, and many other locations will soon follow regardless of whether there is an acceleration of SLRrel. Lastly, we show a regional pattern of increasingly greater event-rate acceleration as the height between MSL and a location’s nuisance flood threshold elevation decreases.
