This Climate Matters analysis is based on open-access data from the National Oceanic and Atmospheric Administration (NOAA). Key concepts:

  • Climate change is supercharging the water cycle, bringing heavier rainfall extremes and related flood risks across the U.S.
  • Some 126 U.S. cities (88% of 144 analyzed) have experienced an increase in hourly rainfall intensity since 1970.
  • Across these 126 locations, hourly rainfall rates are now 15% higher on average than in 1970.
  • Hourly rainfall intensity has increased in every U.S. region, with the largest average increases among cities in the Upper Midwest, Northern Rockies and Plains, and Ohio Valley.
  • People, ecosystems, and infrastructure in both wet and dry locations are facing the risks that come with heavier rainfall.
