BELLINGHAM, Wash. (AP) — The National Oceanic and Atmospheric Administration says high tide flooding has become more common as sea levels rise and is affecting residents of coastal towns and states. Floods that used to only occur during large storms now occur more regularly from simple causes. They include full-moons or changes in currents and winds. High tide flooding is defined as “the overflow or excess accumulation of ocean water at high tide that covers low-lying areas.” It typically occurs when tides reach from 1.75 to 2 feet above the daily average high tide and start spilling onto streets or bubbling up from storm drains.
