"The frequency of coastal flooding from high tides has doubled in the US in just 30 years," reports Oliver Milman, sharing data from the National Oceanic and Atmospheric Administration (NOAA). Moreover, 2017 set the record of flooding days in coastal area: "there was an average of six flooding days per area across 98 coastal areas monitored by the National Oceanic and Atmospheric Administration."

The coastal flooding doing all this damage is known as "sunny day flooding," explains Milman. "[T]hese events swamp streets and homes with water simply from the incoming tide, without the aid of a storm."

"Noaa said that in 2017 areas across the US north-east and Gulf of Mexico were worst hit, with Boston, Massachusetts, and Atlantic City, New Jersey, both experiencing 22 days of flooding, while Galveston, in Texas, was soaked on 18 different days."

NOAA also warns that coastal sunny day flooding is likely to continue to increase in 2018 and 2019.
