If a possible tornado is seen by spotters or detected by radar a tornado warning is issued. The public is then informed of the warning via special TV and radio announcements, as well as through the internet. Some towns sound sirens that warn of a coming tornado.

What does it mean when meteorologists issue a tornado warning?
When a tornado warning means that a tornado has been spotted or detected or if a thunderstorm may produce a tornado at any moment.
What tools meteorologists use to predict and know when a tornado is coming?
Meteorologists use a variety of tools to predict and detect tornadoes, such as weather radar, satellites, weather balloons, and computer modeling. Doppler radar is especially important as it can detect rotations within storms that may indicate the formation of a tornado. Additionally, meteorologists rely on storm spotters, tornado sirens, and public alerts to provide warnings to the public when a tornado is approaching.
How do weather forcasters know a tornado is coming?
There are two primary ways. First is Doppler radar, which measures winds moving toward and away from the radar to detect features in a storm that can produce a tornado, and sometimes the signature of the tornado itself. Then, by simply looking at where the storm is going they can warn places in the potential path. However, radar cannot determine if a tornado has actually touched down, and can occasionally miss a tornado. For this reason there are storm spotters. These are people who report severe weather such as tornadoes to authorities. Through such reports meteorologists (weather scientists) can gain a better idea of the potential threat.
How do meteorologists spot tornadoes?
On valuable tool is doppler radar which can detect the signature of a tornado. Storm spotters are also important. These are people who go out and look for severe weather such as tornadoes and then report the events. Police, emergency workers and the general public can also report tornadoes.
What did meteorologists use to figure out that the Joplin tornado was coming?
The main tool they uses was Doppler Radar. With that radar the meteorologists were able to detect rotation in the approaching thunderstorm and knew that it had the potential to produce a tornado 17 minutes before the tornado itself even formed. This was rather fortunate, as the tornado itself touched down only two minutes before it entered Joplin.
Can scientists and meteorologists predict tornadoes?
yes, to a limited degree. By using tools like Doppler radar meteorologists can predict approximately where and when a tornado is likely to occur. Still, even with a combination of radar and weather spotters we cannot predict the exact path a tornado will take with certainty.
What measures are humans taking to minimise the impact of a tornado?
Scientists are studying tornadoes so that they can better predict them and warn people when they need to get to safety.
What were the meteorologists predictions on the worcester mass tornado in 1953?
Meteorologists knew that severe thunderstorms were possible and that some might produce tornadoes and so issued a severe thunderstorm watch. They did not include any mention of tornadoes in the forecast as they clung to the notion still prevalent at the time that forecasting tornadoes would start a panic. As a result the people were not warned of the Worcester tornado.
Can meteorologists predict the path of the tornado?
To a limited degree yes. A tornado usually moves in the same direction as the storm that produces it. Additionally, it is well known among meteorologists that very strong tornadoes have a tendency to make left turns.
How do they know when there is a tornado?
Meteorologists use a combination of Doppler radar and eyewitness reports. Doppler radar can detect the rotation of a tornado or rotation that may soon lead to one. Newer advancements in radar can now detect debris lifted into the air from trees and buildings. People can also report when they see a tornado.
Why do the tornado sirens turn off?
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.
Are tornado warnings too late?
Not usually. Today the average lead time for a tornado warning is about 15 minutes, which is enough time for most people to get to the safest part of their home but not enough time to evacuate the area. Meteorologists are working to increase the lead time.
