West Pearl River is expected to crest 5 feet above flood stage as officials keep an eye on the area.
West Pearl River in Louisiana's St. Tammany parish is being threatened with flooding, even as Hurricane Isaac weakens and an evacuation order was lifted in the region.
St. Tammany Parish President Pat Brister said the Pearl River is expected to crest to 19.5 feet, five feet over flood stage, and warned residents to be prepared to evacuate if necessary.
"It's going to be a long couple of days,'' Brister told the Times-Picayune.
The region is still reeling from Hurricane Isaac, which left much of the area southeast of New Orleans flooded and thousands of residents without power, CBS News reported.
Most of the areas heavily damaged by Isaac were outside the levee system that was reconstructed with $14.5 billion of federal dollars after the devastating Hurricane Katrina, which left 1,800 dead.
