Flash floods fed by up to seven inches of rain forced closure of low-lying roads and chased hundreds of people from their homes Thursday. Some residents fled in boats.
Creeks that empty into the rain-swollen Mississippi River overflowed their banks in heavy thunderstorms.
"We've had flash flooding all day. It hit pretty suddenly," said Warren County Sheriff Paul Barrett.
Barrett said more than 130 houses in the city were flooded and between 30 and 40 homes in county territory have been flooded. "A lot of them have lost everything they had," he said.
No injuries were reported, the sheriff said.
Gov. Ray Mabus declared a state of emergency in Warren County and called out the Mississippi National Guard to help officials and residents deal with the flooding.
