Residents eager to put behind a historic flood that submerged much of Vicksburg face a long and slow goodbye, forecasters said Friday, predicting that the river could remain out of its banks until at least mid-June. The Mississippi River is not expected to return to its 43-foot flood stage in Vicksburg until after June 14, which is 46 days after it climbed out of its banks, said Amanda Roberts, a National Weather Service hydrologist said. It crested at 57.1 feet Thursday, and the weather service predicts the crest will hold through at least Saturday morning in Vicksburg.
