A quckly-forming storm over the southwest Missouri town of Ozark has produced a tornado that has caused some damage at the high school. Meteorologist John Cagan with the National Weather Service says the storm came out of nowhere and then disappeared as quickly as it came.

Nobody has been hurt. Some homes had minor damage. The tornado touched down at the high school and damaged some bleachers and a field observation tower.

Gagan says no rating has been assigned to the tornado. He says that will be done after analysts review the damage in Ozark.
