At least 82 people have died after floods rushed through central Texas, USA, during the July 4 weekend.

Axar.az reports, citing CNN, the toll includes at least 28 children in Kerr County, where 10 girls and one counselor from Camp Mystic are still unaccounted for. The toll has risen as local emergency officials across the state carry out search, rescue and recovery efforts.

Rising water levels: Waterways in some of the most devastated parts of central Texas are beginning to swell once again as more rain falls in the area. Gov. Greg Abbott said Sunday flash flooding could still pose a danger for some regions of Texas over the next few days as “more heavy rainfall” is expected.

Missing campers: Crews are continuing to search for 10 campers and one counsellor from Camp Mystic, the all girls’ summer camp near the Guadalupe River. Crews are searching by land and air, with the Texas Air National Guard using remotely piloted military drones typically used by the military to conduct surveillance.

Emergency readiness: Records show officials in Kerr County previously considered installing flood warning sirens, but the plan never came to fruition. While the National Weather Service issued a slew of alerts before the storm, questions have been raised about the agency’s staffing and ability to reach residents at the time of the disaster.
