As Harvey continues to dump heavy rainfall over Texas, southwestern Louisiana now faces a threat of flooding from the slow-moving storm.
The former Category 4 hurricane has battered the Texas coast with destructive winds and drenching downpours following landfall on Aug. 25. Widespread and unprecedented flooding is ongoing in the Houston, Texas, area, with thousands of water rescues completed and tens of thousands of 911 calls placed.
In addition to the devastating flooding in southern Texas, there have also been widespread power outages, isolated tornadoes and at least five reported deaths as of Sunday.
Harvey is the first major hurricane to impact the United States since Wilma in 2005.
