This graph shows the number of tornadoes in the U.S. from June 1-22 this year compared to average. We started out with an above average number of tornadoes, but a very quiet late May and June have brought the count well below the average number-to-date of 979. The current number to date of 812 is 167 below average. This is a preliminary count. The number is likely to drop as duplicate reports of the same tornado are eliminated.
We had 351 tornadoes in April, but May – often the month with the most tornadoes in the U.S. – saw only 140 twisters. The total for June 1-22 is just 79 twisters – and that’s fewer than the number that we had in January.
