Flooding forced hundreds of people to flee their homes and closed scores of roads Wednesday across a wide swath of America's midsection as a huge storm system poured as much as 10 inches (25 centimeters) of rain on the region, AP reported. Four deaths were linked to the flooding in Missouri, and five people were killed in a highway wreck in heavy rain in Kentucky. Searches were under way in Texas for a teenager washed down a drainage pipe and in Missouri for a man missing in a creek, and two people were missing in Arkansas after their vehicles were swept away by rushing water. The National Weather Service posted flood and flash flood warnings from Texas to Pennsylvania on Wednesday, and evacuations were under way in parts of Missouri, Arkansas and Ohio.
