Tornadoes began occurring over the affected area on April 30, but the most prolific continuous period was the seven day period of May 4–10. There were 401 tornado reports in 19 states and 1 Canadian province, 1,587 reports of large hail, and 740 reports of wind damage. More severe weather broke out this week alone than any other week in U.S. history. The old record for most tornado reports in one week was 171 during the week of the May 1995 Tornado Outbreak Sequence (May 12 to May 18, 1995). The Super Outbreak of April 3 to April 4, 1974, previously held the record for the most tornadoes produced in a 24 hour period until that record was surpassed by the 2011 Super Outbreak which produced approximately 190 tornadoes in a 24 hour period. The Super Outbreak in April 1974 also produced more significant and violent tornadoes than any other week in history.
