Oklahoma twister tracked path of 1999 tornado

Monday’s powerful tornado in suburban Oklahoma City loosely followed the path of a killer twister that slammed the region in May 1999. The National Weather Service estimated that the storm that struck Moore, Okla., on Monday had wind speeds of up to 200 mph, and was at least a half-mile wide. The 1999 storm had winds clocked at 300 mph, according to the weather service website, and it destroyed or damaged more than 8,000 homes, killing at least two people.
