(3/30/13) Starting Monday the National Weather Service plans to give more detailed severe weather warning in Wisconsin and 13 other states.
The more descriptive information is being offered to help people get to safety sooner when the weather is threatening. The expanded warnings have been tested in Kansas and Missouri. When there is substantial evidence of the approach of a large and dangerous tornado, the warning will include the potential for considerable damage and listeners will be told to take shelter immediately. When a tornado has the potential for devastating damage, the warning issued will include the work "catastrophic."
