On the heels of a deadly weekend of tornado activity in Oklahoma, a much larger tornado touched down there on Monday.
A twister struck just south of Oklahoma City on Monday afternoon, ripping apart homes and other buildings in populated areas.
A mix of volunteers and first responders are combing through debris in an Oklahoma City suburb looking for survivors.
The city of Moore, Okla., was hit by a tornado that was estimated to be two miles wide at one point.
People wearing neon-green vests were joined by residents in the search through rubble. Neighborhoods are flattened and homes blown apart.
This tornado is being compared to the devastating May 3, 1999 tornado that ravaged the same area. Neighborhoods, trailer parks, schools, businesses and other structures in the area are gone.
Shards of wood and pieces of insulation were strewn everywhere. Television footage also showed first responders picking through rubble and twisted metal.
Storms on Sunday killed two people near Shawnee, about 35 miles southeast of Oklahoma City. Gov. Mary Fallin earlier Monday took a tour of the areas hardest hit. She expressed concern that, with power out, Oklahomans might not receive warnings about the new round of storms.
