That is a tragedy, It must be a record for deaths from a tornado.

Not even close:

The Tri-State Tornado of March 18, 1925 killed 695 people in Missouri, Illinois, and Indiana. The outbreak it occurred with was also the deadliest known tornado outbreak, with a combined death toll of 747 across the Mississippi River Valley.

A tornado killed 625 people on March 18, 1925. These storms are terrible, but they are no match for the deaths that occurred before we had good prediction and early warning.

Udall, KS tornado, May 25, 1955

Udall was a town of 610...and suffered 76 fatalities. The town was half-a-mile square and the tornado was a quarter-mile wide at the base. It went thru from SW to NE, leaving only the Northwest and Southeast corners of the town still standing. Everything in the path of the tornado was totally destroyed.

As one who arrived at the scene the next morning, I mean destroyed -- nothing but splinters remained. The only thing comparable that I've seen was the Greensburg, KS storm of two years ago -- where only 3-4 were killed due to ample warning, even though a significant portion of the town was literally flattened.

There have been higher fatalities than Udall, too. Wichita Falls, Waco and Moore, OK all had higher death counts I believe.

[Verginius Rufus]

The World Almanac lists 13 times since 1925 when more than 100 people died in tornadoes either in a single day or on two consecutive days. In 1974 there were 315 deaths in several states on April 3 and 4. Back in 1925 there were 689 deaths on a single day, March 18, in three states.

Today's death toll is already the highest since 1985 for one day (75 killed on May 31) and if the number goes any higher could be the worst day since the 315 in April 1974 (which was over two days but obviously at least 158 on one of the two days).

The worst toll on one day since 2000 was 57 on Feb. 25, 2008.

Here’s another larger fatality outbreak

The OKC meteorologist said it was one of the worst outbreaks over a large area ever. Without warnings, the death count would be much higher. It has to be bad when the OKC weather guys are shaken.
