Authorities say the fatality toll from the devastating tornadoes across the country's south has climbed to 337, making it the second deadliest day for a twister outbreak in US history.
The largest death toll ever was on March 18, 1925, when 747 people were killed in storms that raged through Missouri, Illinois and Indiana.
Alabama was in the path of the most destruction this time with at least 246 deaths.
Authorities on Saturday raised the total number of confirmed dead in several states to 337. The second deadliest day had been in March 1932, when 332 people died, all in Alabama.
The 1925 outbreak was long before Doppler radar could warn communities of severe weather. Forecasters say residents were warned, but the twisters were too powerful to avoid the horrifying body count.
