Please note that a Tornado Warning does not mean there is a Tornado on the ground going to tear apart your house, or even that there is one in your neighborhood. It means that ANYWHERE in your COUNTY, could have a tornado, as there is usually rotation detected. Also, if there is the "C" Shape in the cloud on the radar. Usually, a supercell promts the tornado warning. Also, a watch just means that there is probably a supercell or squall line in your area, and that it is a good condition for tornadoes. However, keep in mind that a tornado warning does mean an area of rotation was spotted, and that there COULD be a tornado on the ground about the rip apart your house, BUT, it doesn't mean that there is a tornado on the ground for sure. Usually, i'd say 3 of 5 tornado warnings have a wall cloud or funnel, and 2 of 5 actually have a twister. A half of one out of 5 usually have an F-4+
