Almost a year after a tornado leveled large portions of Joplin, Missouri, new footage from a hospital security camera shows the devastation as it occurred.

St. John's Medical Center was among the most heavily damaged buildings in Joplin. Winds of 200 miles per hour ravaged the interior. The footage shows chairs and tables swept up and tossed against the ceiling and walls. No people appear in the 36 seconds of video.

The tornado and its aftermath killed more than 160 people. On Monday, President Obama will deliver the commencement speech to the graduating class at Joplin High School. A White House press release reads, "The Joplin community's resilience and selflessness in the face of tragedy continues to inspire our nation."

Missouri Governor Jay Nixon will also attend.
