At least 70 people are dead in central Texas after devastating flash floods slammed Texas Hill Country, with water rescues taking place along the Guadalupe River, which rose rapidly early Friday morning to the height of a two-story building.

Kerr County is home to Kerrville, which was hit hardest by the floods, with local officials confirming 59 people died in the county from the floods. During a Sunday press conference, Texas Governor Greg Abbott confirmed the toll, noting that statewide, there are 41 known missing people related to floods.

Searchers used helicopters, boats and drones to search for victims in flash floods that tore across Texas’s Hill Country at the start of the Fourth of July weekend
