F5 tornado

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.

The afternoon of May 25, 2008 many Iowa residents noticed the sky had turned an eerie shade of green. That was the first sign that something bad was potentially imminent. By the time the day was over, a 43-mile path of destruction would be all that was left after a F5 tornado destroyed many communities in central and eastern Iowa.
