More than 12 million people were under flood warnings across the South early Wednesday as the region struggled to recover from a week of deadly thunderstorms, NBC News reported.
Rivers were still rising in parts of Texas, Louisiana, Arkansas and Mississippi, with 15 river gauges showing major flooding and a further 26 showing moderate flooding.
Although the worst of the rain stopped on Monday, the crest — or highest point — of several swollen rivers now has to move downstream to the sea.
When the flooding finally subsides depends on the severity and location of several lingering, scattered thunderstorms are forecast for the coming days.
