It may have been before opening... I just remember that the attraction was getting a severe rap already... and the banner just had everyone rolling their eyes and wondering if it had been cursed. I also remember one of the times I visited a month later and a car had bottomed out on the first drop and it was shut down. It was not however a tornado. Nothing else was damaged in the storm that pulled through, and it wasn't as bad a storm as this last one... by a long shot.
