NOAA: Record 312 tornadoes in 24 hours last week

AP WASHINGTON – 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 8:00 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 7 states.
