Oklahoma twister tracked path of 1999 tornado

NEW YORK (AP) — 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.

Kelsey Angle, a weather service meteorologist in Kansas City, Mo., said it's unusual for two such powerful tornadoes to track roughly the same path.

The weather service has tentatively classified the Moore twister's wind speeds as an EF-4 on a 5-point scale. Angle said less than 1 percent of all tornadoes reach a EF-4 or EF-5.
