Rescue operations are ongoing in Central Texas after flash flooding along the Guadalupe River left 27 dead and 10 girls and one counselor unaccounted for at Camp Mystic. Officials said more than 100 have died as catastrophic floods ravaged the Hill Country.

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.

Flash flood warnings remain in effect across parts of Central Texas Tuesday morning as thunderstorms and torrential rain continue to soak the region
