‘Clear-sky’ flooding worsens across U.S. as sea levels rise, report says

Got flippers?

High-tide flooding is happening across the USA at twice the rate it was just 30 years ago, according to a new report released Wednesday.

And this flooding isn't necessarily caused by a storm, but by rising seas: As ocean levels rise because of global warming, flooding can now occur with high tides in many locations.

Also known as "sunny-day," "clear-sky" or "nuisance" flooding, 27 locations across the nation set or tied records for most days with floods from May 2017 to April 2018, the report said. Cities such as Boston and Atlantic City both had 22 days with high-tide floods.
