Coastal communities in three locations along the Atlantic and Pacific coasts saw record high tide flooding last year — a trend that is expected to continue into 2023 and beyond without improved flood defenses, according to NOAA.
The newly released information documents changes in high tide flooding patterns from May 2021 to April 2022 at 97 NOAA tide gauges along the U.S. coast. It also provides a flooding outlook for these locations through April 2023 and projections for the next several decades.
“High tide flooding is becoming more common and damaging in many parts of the U.S.,” said Rick Spinrad, Ph.D., NOAA Administrator. “As part of NOAA's work to build a Climate-Ready Nation, we will continue to provide coastal communities with the information needed to anticipate, prepare for and respond to increasingly frequent high tide flooding.”
