Hundreds of workers and thousands of volunteers working to search, rescue and clean up. But who is giving orders?

The remnants of Hurricane Helene thrashed East Tennessee on Friday, causing catastrophic flooding in several communities near the North Carolina border. The big picture: Towns were evacuated and whole homes were carried away by record-breaking floodwaters.

As communities begin regrouping, they're focusing on finding people who are unaccounted for, reopening roads, ensuring there is safe drinking water and finding shelter for people whose homes are damaged.
