Commissioners in Kerr County, Texas, are set to meet Monday in their first official court hearing since more than 100 people, including children and counselors at a summer camp, were killed in catastrophic flooding last week.

In Kerrville, authorities went door-to-door to some homes early Sunday to alert people that flooding was again possible.

FEMA records obtained by NBC 5 Investigates show that Kerr County officials did not use FEMA’s Integrated Public Alert & Warning System to send warnings with safety instructions to all mobile phones in the affected area during critical hours as the flooding began on July 4.
