2012 Tornado and Severe Weather Awareness Drill Scheduled for Thursday April 19, 2012 There are two new and important changes to the 2012 Tornado Drill.his is an historic first in Wisconsin. The tornado warning at 1:45pm will last about one minute on radio and TV stations across Wisconsin. (The drill will also occur at the same time in Minnesota and will be broadcast on radio and TV stations in that state as well).
Tornado paths range from 100 yards to 2.6 miles wide and are rarely more than 15 miles long. They can last from several seconds to more than an hour, however, most don't exceed 10 minutes. Most tornadoes travel from the southwest to northeast with an average speed of 30 mph, but the speed has been observed to range from almost no motion to 70 mph.
