Tornadoes most frequently happen in Tornado Alley, a strip of land that goes up the United States Midwest. However, tornadoes can happen almost anywhere. Flat land, like in Tornado Alley, does not interfere with the winds, so the tornado is not dissipated.

What is a tornado advisory?
There is nothing that is specifically called a tornado advisory, but there are two types of advisory that relate to tornadoes. A tornado watch is issued if overall conditions in a region favor the formation of tornadoes. Meaning there is a risk, but not an imminent threat. A tornado warning is more serious. This means that a tornado has been spotted or detected, or that observations of a thunderstorm indicate that one is likely to form soon. Each of these advisories has a subcategory. A PDS tornado watch (particularly dangerous situation) indicates that a system is likely to produce strong tornadoes. A tornado emergency is an unofficial variety of tornado waring that indicates a large tornado is threatening a populated area and has the potential to cause major damage.
