(May 6, 2007)--The tornado that tore through Greensburg, Kan. this weekend was an F5, the most powerful possible and the same rating as the tornado that killed 27 of the residents of Jarrell in Williamson County almost a decade ago.
The National Weather Service says the Kansas tornado cut a 22-mile track, 1.7 miles wide.
Its winds were clocked at about 205 miles per hour.
At least eight deaths in Greensburg have been blamed on the twister, which leveled the southwest Kansas town.
Meteorologists say the last tornado of that strength in the US was eight years ago.
That storm struck Oklahoma City on May 3, 1999, and killed 36 people.
In Greensburg Sunday, searchers were continuing to pick through the rubble, checking for anyone who may still be trapped under crumbled debris.
