GULFPORT, Ill. (AP) — Floodwaters breached another levee in Illinois on Wednesday and threatened more Mississippi River towns in Missouri after inundating much of Iowa for the past week.

The breach in Meyer, in western Illinois, forced the evacuation of the town of 40 to 50 people and threatened its farmland, Adams County Emergency Management Agency spokeswoman Julie Shepard said. Authorities patrolled the town Wednesday morning to make sure no one was left behind, she said.

Officials monitored levees in other Mississippi River towns in Illinois and Missouri in hopes that they would hold.
