Does a tornado always go counter clockwise?

Answer 1

Most tornadoes north of the equator go counter clockwise. There are a few that will rotate clockwise. These are referred to as anti-cyclonic. They are still destructive. Two well documented clockwise tornadoes occurred in Grand Island, Nebraska in June of 1980. The famous 'Night of the Twisters' book was based on this event which spawned nine tornadoes, one which moved so slowly through a residential neighborhood that a brisk walk would have outrun it. Four died and 150 blocks were devastated.
