Tornado touches down in Ohio

Severe storms across southwest Ohio brought powerful winds and at least one tornado that toppled gravestones, damaged roofs and scattered debris across parts of four counties. In parts of northern Ohio, a flash flood watch was extended into Wednesday night as a new round of storms threatened to dump several inches of rain on areas already saturated from earlier storms. The National Weather Service on Wednesday confirmed at least one tornado touched down at the Dayton Mall near Interstate 75 in Montgomery County, and investigated funnel-cloud sightings Tuesday night elsewhere in Montgomery, Butler, Clermont, Clinton and Warren counties. The storms knocked down trees and power lines, but reports of structural damage were relatively minor -- from damage to roofs of homes and stores to a freestanding sign at a Dayton comedy club being blown over. No serious injuries were reported in the storms, which also knocked over grave markers in a cemetery near Goshen in Clermont County, east of Cincinnati.
