How much time does the public have after they heard that a tornado is coming but before it happens?
It varies. The average lead time for a tornado warning is 14 minutes, but in some cases there is no warning while in others, there have been lead times over 30 minutes. This is based on the ability to issue a warning before a tornado even touches down. If you are warning of an approaching tornado that is already on the ground, it depends on where the tornado is and how fast it's moving. This citizens of Greensburg, Kansas had 39 minutes of warning as a tornado approached their town on May 4, 2007, while Smitville, Mississippi was struck by a tornado that had formed just outside of town less than two minutes earlier.

The lead time for a tornado warning can vary, but it is aimed to give people enough time to seek shelter and stay safe, usually ranging from a few minutes to up to an hour in advance of the tornado's arrival. It is crucial for individuals to have a reliable way to receive these warnings quickly, such as through weather radio or smartphone alerts.
Average lead time for a tornado warning?

What makes a tornado warning a warning?
A tornado watch is when general conditions may lead to a tornado forming. A tornado warning is when a tornado has been spotted in the area or indicated by radar.More Information:In the United States, both the tornado watch and the warning are issued by the Storm Prediction Center in Norman Oklahoma for every location in the country. They are typically issued for 6-10 hour periods and also usually in advance of the anticipated weather. It is left to local National Weather Service offices to detect severe thunderstorms and tornadoes and issue the appropriate warnings. It should be noted that a tornado warning does not necessarily mean that a tornado has been spotted - in fact, the majority of tornado warnings do not pan out as such. Most of these warnings are issued based on a radar signature, i.e. the meteorologist sees something on the Doppler radar that suggests strong rotation and a potential tornado, however more often than not a tornado will not form. However, a tornado warning should still be treated as if a tornado is imminent simply due to the severity of the situation. The last thing meteorologists want to do is not issue a warning when a tornado is in fact on the ground. If there is good evidence that a tornado could be on the ground, the warning is issued and emergency management personnel proceed as such, as the public should follow.Some tornado safety links can be found in the related links.A tornado warning means that a tornado has been spotted by Trained NWS or other Emergency Services Personel , or that Doppler radar indicates a thunderstorm circulation which can spawn a tornado. When a tornado warning is issued for your town or county, take immediate safety precautions. local NWS offices issue tornado warnings.
How much warning in advance are people today given for an approaching large tornado?
It varies considerably. Warnings for major tornado may have a better lead time than averages because the signature is usually easier to detect on radar. Lead time is often 15 to 20 minutes. This can include time before the tornado touches down. However, there is quite a bit of variability. Greensburg Kansas, which was hit by an EF5 tornado in 2007, had 39 minutes warning. By contrast, Cincinnati, Arkansas, which was hit by an EF3 tornado in 2010, had no warning. If you only consider the time after the tornado has touched down, lead times can be shorter, as sometimes a tornado will develop just outside a town, leaving little time to update warnings. In the case of Joplin, Missouri in 2011, the tornado touched down less than a mile outside of town and entered the city two minutes later. A tornado warning has been in effect for 17 minutes before the tornado formed, warning of the potential for a tornado.
