The tornado that devastated Parkersburg, Iowa on Sunday has now been rated an EF-5 by the National Weather Service. An EF-5 is the strongest possible classification a tornado can receive, and is only given to those tornadoes with estimated winds over 200 mph. The winds in the Parkersburg tornado were estimated at 205 mph. At those wind speeds, total destruction of homes occurs. Even those sheltering in basements are not safe–several of the six deaths from the Parkersburg tornado were from people sheltering in basements.
