Tornadoes are always big news, because they are strong storms that we still don't understand very well. Because of their size, speed, and unpredictability, they can cause massive amounts of damage. Yesterday, an unusual tornado touched down in Kansas. Even in an area known for its frequent twisters, this week’s storm was strange in that it lasted on the ground for about 90 minutes, which is 10 times longer than usual. The twister traveled about 23 miles. Luckily, there were no deaths or injuries.
