As the floodwaters rushed into Kerrville, Texas, under the cover of darkness on Friday morning, officers jumped into action to evacuate over 100 homes and rescue more than 200 people in one hour, the police department said.

The Associated Press has assembled an approximate timeline of the 48 hours before, during and after the deadly flash flood, beginning with the activation of the state’s emergency response resources on July 2 — the same day Texas signed off on the camp’s emergency plan for disasters.
