Another week, another rumbling train of tornadoes that obliterates entire city blocks, smashing homes to their foundations and killing people even as they cower in their basements.
With the year not even half done, 2008 is already the deadliest tornado year in the United States since 1998 and seems on track to break the U.S. record for the number of twisters in a year, according to the National Weather Service. Also, this year's storms seem to be unusually powerful.
The brutal numbers for the U.S. so far this year: at least 110 dead, 30 killer tornadoes and a preliminary count of 1,191 twisters (which, after duplicate sightings are removed, is likely to go down to around 800). The record for the most tornadoes in a year is 1,817 in 2004. In the past 10 years, the average number of tornadoes has been 1,254.
"Right now we're on track to break all previous counts through the end of the year," said warning meteorologist Greg Carbin at the Storm Prediction Center, also in Norman.
And it's not just more storms. The strongest of those storms - those in the 136-to-200 mph range - have been more prevalent than normal, and lately they seem to be hitting populated areas more, he said. At least 22 tornadoes this year have been in the top part of the new Enhanced Fujita scale, rating a 3 (for "severe") or a 4 ("devastating") on the 1-to-5 scale.
