Currently average warning time is close to 15 minutes before a tornado strikes. Sometimes there is over an hour of warning, while other times a tornado strikes with no warning.
Presumably you mean to ask how long a tornado lasts. The average duration for a tornado is about 10 minutes. However, tornadoes can last anywhere from just a few seconds to over an hour. The longest lived one on record lasted 3 hours and 29 minutes.
The time it takes for a tornado to destroy something can vary depending on the tornado's intensity, size, and the durability of the object. In many cases, a tornado can cause significant damage within seconds to minutes as it passes through an area.
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.
A tornado is called a rope when it starts to thin out and weaken because its appearance resembles that of a long rope hanging from the clouds. This stage typically signals that the tornado is losing strength and will soon dissipate.
The average time for a tornado to stay on the ground is around 10-15 minutes, but they can last anywhere from a few seconds to over an hour, with some particularly long-lasting tornadoes staying on the ground for hours.
It is impossible to make long-term predictions about where one when a tornado will strike.
until the tornado ends and then the people fall and die or get injured

The longest-tracked tornado in Illinois actually had such a long track that it could not be contained withing Illinois. The Tri-State tornado holds the record with a 219-mile-long damage path across portions of Missouri, Illinois, and Indiana. This tornado killed at least 695 people, most of them in Illinois, making it the deadliest tornado in U.S. history.
The deadliest tornado in Illinois history was the Tri-State tornado of March 18, 1925. This F5 tornado tore a 219-mile-long damage path across portions of Missouri, Illinois, and Indiana, killing at least 695 people, making it by far the deadliest tornado in U.S. history. A least 606 people died in Illinois.
The worst tornado in U.S. history was on March 18, 1925. Called the Tri-State tornado, it tore a 219 mile long path across Missouri, Illinois, and Indiana, killing 695 people.
The Tri-State Tornado of March 18, 1925 claimed the most lives of any single tornado, killing 689 people in 3½ hours on its 219-mile long track. This tornado also was the third-fastest tornado on record, traveling at nearly 60 miles per hour.
most likely in a long time but scientist are detecting black holes coming closer to earth.
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.
The worst tornado to strike the United States was the Tri-State tornado of March 18, 1925. This F5 tornado tore a 219-mile-long path of destruction across parts of Missouri, Illinois, and Indiana, ravaging many towns and killing an estimated 695 people.
Tornado sirens are typically turned off after the threat of a tornado has passed or when it is no longer necessary to warn people of immediate danger. This helps prevent confusion and panic among residents in the area.
The deadliest tornado in southern Illinois was the Tri-State tornado of March 18, 1925, the deadliest tornado in US history. This F5 tornado tore a 219-mile-long path of destruction across parts of eastern Missouri, southern Illinois, and southern Indiana, killing 695 people. Of those, 606 were in Illinois.
