Parts of eastern Missouri south of St. Louis could get up to 9 additional inches of rain through Wednesday.

Rivers and creeks are already flooding. The Mississippi is at or approaching major flood stage in several communities. The Missouri River is also flooding, and many tributaries are rising.

Among the hardest hit areas so far is St. Francois County, about 70 miles southwest of St. Louis. Farmington fire crews had to rescue several people from homes and cars over the past few days due to flash flooding. High water damaged a couple of apartment complexes, forcing residents to temporarily relocate.
