At least 43 people, including 15 children, died in Kerr County after a storm unleashed nearly a foot (0.3 meters) of rain on Friday and sent floodwaters gushing out of the Guadalupe River through the hilly region known for its century-old summer camps.

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.

Kerrville police said they worked overnight and are continuing rescue efforts Saturday after catastrophic floods came through the area on Friday.
