Residents in Mississippi's Delta region are bracing for a flood threat that's expected to continue through Saturday night.
The National Weather Service said the area most at risk of flooding is along the western side of the state, near the Mississippi River.
The Delta Democrat-Times reports that city and county crews on Thursday were filling sandbags after heavy rain caused some flooding in parts of Washington County, home to the city of Greenville.
Anna Wolverton, a forecaster with the National Weather service in Jackson, said 3 inches (8 centimeters) of rain had fallen within a 24-hour period at Greenville's airport, which is about 100 miles (160 kilometers) northwest of Jackson, Mississippi.

Officials in northern Indiana's largest city were forced to shut down its wastewater treatment plant as it was swamped by flooding from a record-high river crest caused by heavy rain and melting snow in parts of the Midwest.
The city of South Bend says the treatment plant restarted at limited capacity Thursday morning after being shut down overnight. The plant shutdown forced it to release untreated sewage water into the St. Joseph River.
The National Weather Service says the river crested at 12.7 feet (3.87 meters) late Wednesday — nearly 2 feet (0.61 meters) higher than its previous record.
Mayor Pete Buttigieg (BOO'-tah-juhj) issued an emergency declaration for the city, allowing for tougher enforcement of numerous street closures. Officials haven't yet estimated the extent of building damage.

In Michigan, states of emergency were declared in the Lansing area as officials recommended the evacuations of several neighborhoods. Flooding also hit nearby Michigan State University.
