The onslaught from heavy rain is not over for the South-Central states as more rounds are on the way that will bring renewed flooding in some locations and initiate flooding in others into mid-May.

At least two people were reported to have died as heavy rains soaked the region. More thunderstorms were expected on Thursday.

The south-central U.S. is facing a "heightened" risk of flash flooding into Thursday following days of deadly storms across a region that's spanned from Texas to the Northeast, the National Weather Service warns.
