More than an entire summer’s worth of rain fell in some spots in central Texas in just a few hours early on the Fourth of July, quickly overwhelming dry soils and creating significant flash flooding. Central Texas is currently home to some of the worst drought in the United States and bone-dry soils flood very quickly.

A July Fourth weekend deluge in Texas caused catastrophic flash flooding that has killed more than 80 people. Camp Mystic in Kerr County says Monday morning that it is “grieving the loss” of 27 campers and counselors as the search continues for victims of the disaster.
