EDMOND, Okla. - One of several tornadoes that touched down Sunday in Oklahoma turned homes in a trailer park near Oklahoma City into splinters and rubble and sent frightened residents along a 100-mile corridor scurrying for shelter.

The tornadoes that touched down in Oklahoma, Kansas and Iowa were part of a massive, northeastward-moving storm system that stretched from Texas to Minnesota.

At least four separate tornadoes touched down in central Oklahoma late Sunday afternoon, including the one near the town of Shawnee, 35 miles southeast of Oklahoma City, that laid waste to much of a mobile home park.
