Wisconsin ? Relentless thunderstorms pounded parts of the Midwest and the Plains on Monday, causing mudslides, washing out bridges and flooding towns. At least 12 people have died since the weekend.

Remnants of Tropical Storm Erin dumped heavy rain in southwest Missouri on Monday, leaving one town temporarily cut off. Over the weekend in Oklahoma, the same system swamped buildings, led to dozens of water rescues and left six dead.

In southwestern Wisconsin on Monday, emergency workers braced for more rain and flooding. A storm system over the weekend left six dead in southeastern Minnesota; one man was still missing Monday.

As the light rain continued to fall in southwestern Wisconsin Monday morning, there were stark reminders of the flooding. Two days of thunderstorms turned the countryside into swamps, drowned crops, eroded bluffs and strained dams.

In Missouri, some of the worst damage was in Pleasant Hope, a town of 700 residents near Springfield. Dozens of homes were damaged or destroyed, emergency management director Rick Davis said. Some parts of the town got 15 inches of rain in a four-hour period.
