Abstract

It is widely believed that tornadoes move from the southwest. However, 30 percent of all Iowa tornadoes move instead from the northwest quadrant, and the majority of summer tornadoes come from this direction in the upper midwest. The greatest recorded outbreak of northwest-type tornadoes occurred on June 28, 1979, when 27 such twisters touched down in North Dakota, Minnesota, and Iowa. Ten of these were in Iowa, including the destructive Algona and Manson tornadoes. Meteorological information, satellite cloud imagery, and eyewitness accounts of the 1979 outbreak and especially the Manson storm are used here to illustrate this less-well-known class of tornadoes.
