Heavy rains from the remnants of Hurricane Delta triggered flash flooding and violent weather across the Southeast on Sunday -- even washing out tracks, which led to a train derailment in Georgia.

The National Weather Service (NWS) forecast office in Atlanta said the storm system dropped 2 to 3 inches of rain across Atlanta's metropolitan area, with some locally higher isolated amounts.

Those heavy rains led to a train derailment in Lilburn early Sunday, located northeast of Atlanta.
