Kerr County, Texas, lacked a “last mile” warning mechanism that could have saved residents before the deadly floods devastated the area, including a children’s summer camp, killing more than 80 people.

Emergency responders continue to search for missing people and local police said efforts have been slowed by "sightseers who are making things worse."

After deadly floodwaters swept through Central Texas, there are questions about the timeline of weather alerts and possible gaps in the warning system.
