The number of days with high tide flooding in 2016 was above the local flood‐frequency trend at the majority of the 28 locations examined (more than half of the trends are accelerating in time). Three all‐ time records for annual‐flood days were either tied (Key West, FL) or broken (Charleston, SC; Savannah, GA). If an El Nino develops this coming year (May 2017 ‐ April 2018) as model guidance suggests is possible, the frequency of daily floods may be compounded relative to long‐term trends, upwards of 25% or more at several U.S. West and East Coast locations.
