An F-4 is described as ““devastating.’’ It turns large objects into missiles, cars into loose change. Last week’s disaster was declared a rare F-5, classified as ““incredible.’’ The Fujita scale compares it to an atomic bomb.

And it kills. Gathering up quickly, the skinny smudge hurled winds of more than 200 miles per hour. At a subdivision in the farming town of Jarrell, 40 miles from Austin, rescue workers have found 27 bodies amid the flattened wreckage. A series of nearby tornadoes claimed two more lives. And those, of course, were the important numbers.
