Authorities now say fewer than ten people were hurt by last night’s tornadoes which struck northern Black Hawk and Buchanan counties. Earlier estimates were twice that, although a specific number is still unavailable. Black Hawk County Sheriff’s Deputy Tony Thompson says only one person is in critical condition. The woman was pinned in a house that collapsed around her and she may have lost one or both arms. Deputy Thompson says between ten and 13 homes are either badly damaged or destroyed, although he says the toll could have been much worse. The twisters struck within three miles of Waterloo/Cedar Falls. Thompson says many hundreds of people are still without electricity according to MidAmerican Energy officials. It may take one to four days to repair the damaged substations and the many downed power lines. 25-hundred people are without power. Thompson is putting out a plea to anyone who wants to see the damage up-close — to forget it — and watch the T-V news. He says several tornado sirens did NOT sound last night due to power outages.
