Historic rainfall fell last week in Central Texas, with the Guadalupe River rising 25 feet in 45 minutes around 4:30 a.m. on Friday, July 4. At least 84 of the confirmed fatalities are in Kerr County, Texas, including at least 27 at Camp Mystic, a summer camp along the river. Last week, Mr. Trump signed a disaster declaration for the region.

At least 81 people, including more than two dozen children, died in the torrential downpour. Dozens more were still missing three days later.

The flood disaster in Texas claimed dozens of lives. Extreme floods also bring dangers in parts of California, although experts say there are differences.
