Texas floods kill over 100, prompt questions about disaster preparedness

Zoom in: Camp Mystic, a private Christian camp for girls, confirmed on its website that 27 campers and counselors had died following the flooding. "Our hearts are broken alongside our families that are enduring this unimaginable tragedy," a statement read. "We are praying for them constantly."

Local and federal officials have said they had not expected such an intense downpour of rain and insisted that no one saw the flood potential coming.

The massive rain flowing down hills sent rushing water into the Guadalupe River, causing it to rise 26 feet (8 meters) in just 45 minutes.
