Over the holiday weekend, a catastrophic flash flood swept through Central Texas, leaving at least 80 people dead and more than a dozen missing after torrential rains sent rivers surging over their banks within a matter of hours. While rescue efforts are ongoing, the event has quickly become one of the deadliest disasters in Texas history, with the full extent of the damage unfolding by the minute.

On the East Coast, tropical storm Chantal made landfall in South Carolina on Sunday, delivering up to 10 inches of rainfall as it moved inland. The tropical depression is heading northeast, where it will bring several inches of precipitation to parts of Maryland and New Jersey.

The dual extreme rainfall events are causing unprecedented flood activity in large swaths of the country. There are currently 124 counties under flood watches from the National Weather Service, representing more than 24 million Americans. Streamflow levels are at or near record highs in dozens of rivers, with water levels multiple feet above flooding thresholds. A closer look at real-time data from the U.S. Geological Survey reveals the places where flooding is at historic extremes right now.

To determine where flooding is at historic extremes right now, Climate Crisis 247 reviewed data on current flooding observations from the U.S. Geological Survey. Stations were ranked based on the historic percentile of current streamflow for July 7, 2025. Stations where current streamflow conditions are in the highest percentile – meaning where streamflow levels are at their most record-breaking – were ranked highest. Supplemental data on current water levels and flooding thresholds are also from the USGS. Station locations were paired to Census Bureau places using nearest neighbor analysis.
