The average lead time for a tornado warning is 14 minutes.
The average lead time for a tornado warning is 15 minutes.
Although they are driven by completely different mechanisms, both earthquakes and tornadoes are natural disasters that strike suddenly and are difficult if not impossible to predict. with a tornado you usually get a few minutes warning. With an earthquake there is no warning.
A warning is generally the worse advisory. Although it differs depending on which sort of watch or warning is issued, a watch means a particular event is possible. For example, if there is a tornado watch, it means that conditions are favorable for a tornado to form. A warning means the event is expected or probable. In a tornado warning, for example, it means that a tornado has been spotted or is forming.
The NOAA states that the current average warning time before a tornado-due to advances in weather technology, such as Doppler radar-is 13 minutes. The residents of Moore, Oklahoma, got 16 minutes lead time, but this may have been due to Oklahoma having more spotters than other areas. The technology is steadily improving, but at this point I don't think you can say 20 minutes. Going by the NOAA and Moore, Oklahoma, information, I would say that the answer is an average of thirteen minutes, with isolated incidents of a few more minutes.
A tornado warning means that a tornado has already been spotted or is likely to form in the next few minutes. The tornado may be only minutes away from your location, so if a tornado warning is issued, take cover immediately.
That would be a tornado. Once the process starts, a tornado can form in a matter of seconds. Hurricanes, by contrast, usually take several days to form and are easy to track.
Joplin was under a tornado warning for about 17 minutes before the tornado formed and 19 minutes before it entered the city.

Average lead time for a tornado warning is about 15 minutes. In rares cases it can be over 30 minutes.
It varies quite a bit. The average warning time is about 15 minutes.
The average lead time for a tornado warning is 14 minutes.
Severe thunderstorms have the potential of producing a tornado with little or no advanced tornado warning.
It varies. The average lead time for a tornado warning in the United States is 14 minutes. However, in recent years lead times have been as long as 39 minutes, while in other cases there has been no warning.

Partially. A tornado warning means that a tornado is likely to form or already has formed.
