AccuWeather said the private forecasting company and the National Weather Service sent warnings about potential flash flooding hours before the devastation.

At the all-girls Camp Mystic, located in Hunt – about 17 miles from Kerrville – staff notified parents that all campers at Cypress Lake and Senior Hill are accounted for, adding that those whose daughters are "not accounted for" have been notified.

Flash floods in central Texas have led to at least 27 fatalities, including nine children, with many still missing, particularly from Camp Mystic. Patrick Keely/via REUTERS THIS IMAGE HAS BEEN SUPPLIED BY A THIRD PARTY. MANDATORY CREDIT. NO RESALES. NO ARCHIVES. (Patrick Keely via REUTERS)
