El Niño and Climate Change Drive Record U.S. Rainfall
US · Published Aug 24, 2026
The United States has experienced record-breaking rainfall this summer, driven by an unprecedented combination of El Niño, a marine heatwave, and climate change.
Atmospheric moisture levels have been 5-15% above average, contributing to extreme weather events across 44 states.

Impact & Risks

The elevated atmospheric moisture has led to destructive flooding in states such as Hawaii, Indiana, Kentucky, Missouri, New York, Texas, and West Virginia. These events have caused significant damage to infrastructure, homes, and communities. The risk of further flooding remains high, particularly in the southern United States, as the subtropical jet stream is expected to intensify during the fall and winter.
