NOAA experts to summarize 2019 high tide flooding in the U.S., provide 2020 outlook

July 8, 2020
Sea level rise is turning nuisance flooding into a “sunny day” event — high-tide flooding that occurs even without a storm.

On July 14, NOAA will release its 2019 State of High Tide Flooding and 2020 Outlook for the U.S. The study tracks changes in coastal high tide flooding from May 2019 to April 2020, and provides projections for next year using national flooding thresholds at 98 NOAA tide gauges around the U.S.  

High tide flooding, sometimes referred to as nuisance flooding, is coastal flooding that leads to public inconveniences such as road closures. It is becoming increasingly common as sea levels rise. NOAA has released an outlook on coastal high tide flooding every year since 2014.
