The three-day period from 25-28 April saw 362 tornadoes strike, including some 312 in a single 24-hour period.
The previous record was 148 in two days in April 1974.
The tornadoes and the storm system that spawned them killed at least 350 people in Alabama and six other states. It was the deadliest outbreak since 1936.
