The National Oceanic and Atmospheric Administration (NOAA) has released its 2017 State of U.S. High Tide Flooding with a 2018 Outlook report. The study looks at coastal high tide flooding around the U.S. based on new, national flooding thresholds and focuses on more impactful floods affecting some communities. High tide flooding, sometimes referred to as nuisance flooding, is coastal flooding that leads to public inconveniences such as road closures. As noted by NOAA, high tide flooding is becoming increasingly common as sea levels rise. Among the report’s key points, it notes the nation-wide average annual frequency of high tide flooding hit an all-time record of six flood days in 2017. For 2018, the report predicts that annual flood records will continue to be broken at locations along the U.S. coastline. Additionally, it forecasts that if high tide flooding follows historical patterns, flooding will be most common during the winter months on the West Coast and the Northeast and during the fall in the Southeast. NOAA.
