DETROIT: At least seven people died late Wednesday when powerful thunderstorms ripped through the Midwest, uprooting trees and lifting homes off their foundations. In the wealthy Detroit suburb of Grosse Pointe Farms, three children and two adults who sought shelter in a waterside gazebo were killed when strong winds swept the little building into the air and sent it crashing into Lake St. Clair. On the east side of Detroit, witnesses said a tornado lifted a house off its foundation and tossed it several feet into an alley. A 38-year-old woman from Mount Morris Township, near Flint, was also killed by a falling tree. "It looked like "The Wizard of Oz,'" said one local resident. The storms blanketed Michigan, Indiana and Ohio with dark, menacing clouds, drenching the region with heavy rains that left some roads flooded up to car windshields.
