USA - NOAA Warns of 'Extraordinary' Increase in Coastal Flooding

The National Oceanic and Atmospheric Administration (NOAA) said Tuesday that a trend of increased coastal flooding will continue to worsen as the climate crisis escalates.

Increased flooding is happening even without storms. "Nuisance" or "sunny day" high-tide flooding is becoming more commonplace across the U.S., according to the NOAA report that warns such flooding will worsen in the decades to come as seas continue to rise, according to USA Today.

The agency noted record levels of high-tide flooding in 2019. Some of the hardest hit areas were on the Atlantic and Gulf coasts, where the increase in high-tide flooding has been "extraordinary," according to the report, 2019 State of High-Tide Flooding and 2020 Outlook.

The number of days with high-tide flooding set or tied records in 19 places around the country last year, including Corpus Christi, Texas, which recorded 18 days of flooding; Galveston, Texas (18 days); Annapolis, Maryland (18 days); and Charleston, South Carolina (13 days), as The New York Times reported. The place with the greatest number of recorded flood days was Eagle Point, Texas, in Galveston Bay; it dealt with high-tide flooding on 64 days, or about one out of every five days.
