WASHINGTON (AP) - Preliminary government estimates say there were more tornadoes in a single day last week than any other day in U.S. history.
Government analysts said Monday there were 362 tornadoes during last week's outbreak, including a record-setting 312 in one 24-hour period.
The National Oceanic and Atmospheric Administration said the largest previous number on record in one event occurred from April 3-4, 1974, with 148 tornadoes.
NOAA says 340 people were killed during the 24-hour-period from 8 a.m. Wednesday to Thursday.
It was the deadliest single day for tornadoes since the March 18, 1925, tornado outbreak that had 747 fatalities across seven states.
