Additional clusters of storms through this evening could down trees and knock out power from Indiana and Ohio to eastern Kentucky and the central Appalachians. Widespread power outages: More than 800,000 homes and businesses across Illinois, Indiana, Ohio, West Virginia and Virginia were without power early Tuesday afternoon, according to PowerOutage.us. Flash flood emergency: Water rescues are ongoing in Perry County, Ohio, the state's emergency management director told CNN. Areas where the ground is already waterlogged because of storms earlier in the week will be even more prone to flooding. Over 6 inches of rain is close to double the average August rainfall of 3.43 inches in Cincinnati and 3.75 inches in Charleston, West Virginia.
