NOAA map highlights U.S. coastal cities at risk from rising sea levels

A new map from NOAA shows which U.S. coastal cities may be affected by rising sea levels. Projections indicate an average rise of 10 to 12 inches by 2050, with significant risks for cities along the Atlantic, Gulf, and Pacific coasts. Cities like Miami, New Orleans, and San Francisco are highlighted as at risk. The map indicates areas that could experience partial flooding, with dark blue regions showing the most significant projected rises. Experts note that while no cities are expected to be permanently underwater by 2050, increased flooding events could occur more frequently. Rising sea levels may lead to episodic flooding, impacting communities even on sunny days.
