Flash-flood watches were in effect for much of Louisiana and parts of southern Arkansas and Texas, with up to 5 inches of rain expected across the region, the National Weather Service said.
"This will result in additional significant and possibly life-threatening flooding," it warned. "Flooding of rivers and lakes will be an ongoing threat for the next several days and likely into next week."
