While tornado season isn’t exactly defined, it is said to go from late winter to mid-summer. Although tornadoes can happen anytime of the year if conditions are right, tornado season marks the time when tornadoes are most likely to occur.
In the most recent report found for 2009, according to USA Today, at the end of June there had been 21 deaths caused by tornadoes in the United States on the year so far. This is way down from the 121 deaths caused by the same time last year. The annual record for deaths due to tornadoes is 794 which occurred in 1925.
