At least 90 people have died in central Texas in extraordinary floods, the deadliest in the Lone Star State since Hurricane Harvey killed 89 people.

A torrential downpour started off the July 4 weekend with several months’ worth of rain falling in a few hours, lifting water levels in the Guadalupe River as high as 22 feet. Among the dead are 27 children and counselors at a summer camp near Kerrville in Kerr County. One adult at the camp may have died trying to rescue children. More people are still missing, and more rain is in the forecast.
