Devastating flash floods from a storm that pounded central Texas have killed at least 51 people. Officials say the death toll is 43 and likely to grow in the hardest-hit area of Kerr County.

Texas Gov. Greg Abbott said emergency responders remained in a search and rescue posture, hours after the flooding along the Guadalupe River inundated nearby areas. "So many people have been swept up into an extraordinary catastrophe," Abbott said, asking for prayers for residents.

At least 24 people are dead and more than 20 campers are missing after flash floods tore through Texas, prompting massive rescue efforts and leaving families desperate for answers.
