"Eight locations along the nation’s Atlantic and Pacific coasts experienced a record surge in high-tide flooding days last year, a trend intensified by rising sea levels and weather patterns that El Niño is expected to escalate in 2024, NOAA said Tuesday.
Coastal communities are expected to face three times as many high-tide, or “sunny day,” flooding instances through next April, compared to two decades ago, agency officials said in a press call.
“Increased high-tide flooding is not isolated to a few regions but is accelerating in many locations across the country due to sea-level rise,” said Nicole LeBoeuf, assistant administrator for NOAA’s National Ocean Service. “A new factor in the mix this year is the strengthening of El Niño conditions that are predicted to further amplify high-tide flooding frequencies at more than a third of NOAA’s tide gauge locations in the East and West coasts.”"
