GLENDORA, Miss. (AP) — Rain-swollen rivers were spilling over their banks across the South on Wednesday and a Mississippi mayor said water has surrounded his town and forced some families to leave their homes.

Flood warnings were in place Wednesday in parts of Arkansas, Louisiana, Tennessee, Mississippi, Alabama and Georgia.

In Glendora, Mississippi, the town of 151 people was caught between the flooded Tallahatchie River to the north and the Black Bayou to the south, The Greenwood Commonwealth reported.

The water was within inches of covering U.S. Highway 49 in both directions, Glendora Mayor Johnny Thomas said.

"I hope it doesn't get worse," he said. "We've only got one way out of here."

City workers filled sandbags Tuesday afternoon and a shelter opened for those displaced.

Near the Alabama-Mississippi line, the Tombigbee River crested nearly 20 feet (6 meters) above flood level, just short of a record, surrounding rural homes and covering fields. Flooding already was occurring downstream, and forecasters said the water would continue rising through the rest of the week.
