Thirteen people are dead and more than 20 people unaccounted for after heavy rain lashed Texas, leading to "catastrophic" flooding. Children are among the dead, and about 23 campers from a summer camp in the area, Camp Mystic, are unaccounted for, said Lt. Gov. Dan Patrick, who has taken on the duties of acting governor.

Daniel Morales, assistant chief of the Comfort Volunteer Fire Department, believes that long, flat tone the morning of July Fourth saved lives.

Officials at the Comfort Volunteer Fire Department triggered a flood warning siren last week when the Guadalupe River began to swell

Officials are being pressed about their response and whether there could have been a better warning system.
