The tornado is believed to have been at least an F4, possibly an F5 (the highest category) with a 2-mile wide debris ball. KFOR's news anchor described it as "ripping up everything in its sight," and reporters on the ground said it was leaving "Atomic bomb-like devastation."
The National Weather Service issued a "tornado emergency" for the Oklahoma City area, and has called the tornado "large and extremely dangerous," USA Today reports.
KFOR reporters say that at least two schools in Moore have been hit by the tornado and severely damaged. One reporter described seeing third graders being pulled out of school after the storm, and there are reports that 75 people were in Plaza Towers Elementary school when the tornado hit.

The Associated Press reports that Moore was hit hard by a tornado in 1999 that included the highest winds ever recorded near the earth's surface. A meteorologist for KFOR is predicting that today's tornado may have left more damage.
