How can a double tornado stay on ground?

A "double tornado" is scientifically known as a multiple vortex or multivortex tornado. In such tornadoes smaller vortices form within the main vortex of the tornado. These subvortices usually do not last long and individually do not impact the overall tornado very much. Rather than indicating a lack of organization in the tornado, a multivortex structure usually indicates a strong tornado.

How long does it take to destroy structures with a tornado?

It varies depending on the structure and the intensity of a tornado. In most cases, though, it takes a matter of seconds, which is usually how long a structure is exposed to the strongest winds. One analysis of the fast-moving EF5 tornado that hit Smithville, Mississippi tornado of 2011 found that houses wiped clean off their foundations were exposed to the strongest winds of the tornado for less than 3 seconds.


How long does a tornado last for landing in the ground?

Can you predict if a Tornado is coming?

To a limited degree. It is possible to detedct a tornado and its immediate precursors with Doppler radar, but this cannot tell when the tornado will touch down, how long it will last, or if it will change course. Beyond this, weather conditions can tell if a given areas is at risk from tornadoes on a given day, but cannot tell where indivitdual tornadoes will strike.
