Heavy rains caused multiple rivers in Central and North Texas to swell by more than 20 feet. Search efforts for victims of the July Fourth floods were suspended until Monday.

A National Weather Service advisory warned of another 2-4 inches of rain falling in the region − and isolated areas could see 9-12 inches.

The heavy showers have caused Flash Flood Warnings across Central Texas and prompted officials to close low-water crossings, roads and parks.

There are more than 100 emergency personnel on the ground working to reunite families, the sheriff said. A large-scale search and rescue effort is ongoing.

A "Basic Plan" for emergency response for three Texas counties labeled flash flooding as having a "major" impact on public safety, according to a page on a city website.

Some camps in the region had to be evacuated, and local newspapers described how Camp Mystic was among those cut off from the outside world. According to a Kerr County history book, floodwaters at Camp Mystic almost reached the top of the dining hall’s stairs.

July Fourth brought "life-threatening flash flooding" to the Kerrville area. More than 20 children remain unaccounted for from nearby Camp Mystic.
