Torrential rains and flash floods were expected to lash the Gulf Coast again on Friday amid a rash of severe weather that has killed at least five people across the South.
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."
In Louisiana, local deputies and National Guard personnel made a number of dramatic rescues and helped evacuate flood-stricken residents.
More than 3,500 people have been evacuated so far and at least three people in the state have died, the governor's spokeswoman Shauna Sanford told NBC News.
Statewide, at least 5,000 customers were without power as of 8 a.m. (9 a.m. ET), according to power firm Entergy.
In Mississippi, Governor Phil Bryant declared a state of emergency in order to assist areas affected by the flooding.
While the rain isn't expected to dangerous, forecasters are hopeful it could signal a turnaround from a dry February that was only exacerbated by the warmer, summer-like conditions.
