Instruction: 
Anyone outdoors should move to shelter inside a well-built structure and stay away from windows. These storms are capable of producing widespread damaging winds. Intense thunderstorm lines can produce brief tornadoes and widespread significant wind damage. Although a tornado is not immediately likely, it is best to move to an interior room on the lowest floor of a building. These storms may cause serious injury and significant property damage. A Tornado Watch remains in effect until 1200 AM CDT /1100 PM MDT/ for portions of south central and southwest North Dakota.
