It’s a below-average year for tornadoes in Iowa. While they can strike during any month of the year, the peak time for twisters in the state is usually during May and June. Kevin Skow, a meteorologist at the National Weather Service in Des Moines, says Iowans should not let their guard down as tornadoes can still happen.
Of the 33 tornadoes confirmed in Iowa this year, 24 of them were rated in the weakest category of E-F-zero, while seven were E-F-ones and only two got big enough to rank as E-F-twos. There have been no E-F-threes, fours or fives.
The first three confirmed tornadoes this year all touched down on March 15th in Scott and Clinton counties, while the most recent tornado was just last week in Council Bluffs.
