These Are Iowa’s Worst Tornado Outbreaks
The tornado outbreak of May 15th, 1968 was the worst outbreak of such weather in Iowa's recorded weather history. Between mid-afternoon and early morning on the 16th, there were a total of 39 tornadoes over 19 states. In Iowa, there were five tornadoes (two F1s, one F2, and two F5s) that caused 18 deaths and over 600 injuries.
One tornado traveled through Franklin, Butler, Floyd, Chickasaw, and Howard causing damage in its path over 61 total miles, a little after 4 pm. The worst of it was in Charles City where it swept through the downtown area. 450 were injured, 76 were put in the hospital, and there were 13 fatalities. A total of $30 million in damages with 337 homes totally destroyed.
The same tornado continued on to Elma where it's estimated it caused over $1.5 million in damage, injuring 12 and hospitalizing 3 people. After it passed through Elma, it dissipated but not before several rural homes and farms were damaged or completely destroyed.
On that same day, about 45 minutes later, another tornado in Fayette County landed and tore through Oelwein and moved through Maynard. There were no fatalities but 956 families were affected by the destruction. Of the 156 injuries, 34 were hospitalized and total damage was estimated near $21 million.
AT 5:45 pm, another funnel cloud was seen and became a tornado after landing in Audubon damaged 2 farms before dissipating.
If this wasn't enough, a half-hour later, yet another tornado was spotted traveling through Howard and Winneshiek counties where no one was injured and the only damage was debris from farm fields that had only just been planted.
According to NOAA, the only two F5s in the whole 10 state outbreak were the ones in Charles City and Oelwein. Since 1968, only two other F5 tornadoes have hit Iowa. One on June 13, 1976, in Jordan and another on May 25, 2008, that leveled Parkersburg.
