Dozens of people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

As in Friday’s flooding, in 1987, five to 10 inches of rain fell in the upper headwaters of the Guadalupe River basin. In Hunt, Texas, where the Guadalupe River forks, over seven inches had fallen since Thursday afternoon, which was the highest total at the site since the early 1990s.

Local officials have faced angry questions about whether they could have warned people of dangerous flash floods in Texas Hill Country sooner. Rescue teams from neighboring states and Mexico have joined local efforts to search for survivors,
