Survivors have described the floods along the Guadalupe River as a “pitch black wall of death” and said they received no emergency warnings.

The flooding brought the Guadalupe to its second-highest point in history, according to the National Weather Service, which urged people in the affected area to move to higher ground.

The risk of life-threatening flooding is still high in central Texas with more rain on the way. Searchers now have found 68 bodies in Kerr County, where a wall of water came down the Guadalupe River.
