Most severe thunderstorms do not produce tornadoes. If a tornado is detected or it is believed a storm might produce one a tornado warning is issued, which is more serious than a severe thunderstorm warning. A thunderstorm that produces a tornado is automatically classified as severe even if other severe weather (damaging non-tornadic wind or large hail) does not occur.
What else can I help you with?
Have there ever been violent tornadoes in a severe thunderstorm watch?
Yes, extremely violent tornadoes can occur within severe thunderstorm watches. Severe thunderstorm watches indicate conditions are favorable for the development of severe thunderstorms, which can produce tornadoes with little warning. It is important to stay informed and be prepared for rapidly changing weather conditions during such watches.
What is a severe weather alert?
The severe weather watch is when a group of meterologist decide that conditions are appropriate for an abnormally severe storm to occur. They will then alarm the public that it is likely for one of these storms to occur. Therefore, it is a good idea to be on the look out to prevent injury.
What indicates that a tornado warning should be given?
A tornado watch is issued when general weather conditions in a region are favorable for the formation of tornadoes. Tornado watches are numbered in the order that they are issued. So tornado watch 4 is the 4th tornado watch issued in the country that year.
Why should you be on the lookout for tornadoes during a severe thunderstorm?
tornadoes occur most often in the Great Plains but they can and do occur in nearly every part of the United States that if you hear a tornado warning move to a safe area as soon as you find the safest place to be during a tornado is in the basement of a well built building.
What is a tornado alarm?
A tornado alarm is a warning system that is used to alert people of an impending tornado. It is typically a loud siren or whistle that sounds when a tornado is spotted or conditions are favorable for one to occur, allowing residents to seek shelter and take necessary precautions.

How long does it take for a tornado to change from a cloud to a tornado?
The transformation from a thunderstorm cloud to a tornado can occur rapidly, typically within a matter of minutes. This process involves the development of a severe thunderstorm with rotation that can quickly strengthen and produce a tornado.
What is the difference between a weather watch a weather advisory and a weather warning?
A severe weather watch informs you when the conditions are right for severe weather to happen, while a warning means it is happening or is imminent, and is warning you to take immediate action.

Where in the storm does a tornado happen?
A tornado forms within a supercell thunderstorm, which is a type of severe thunderstorm with a rotating updraft called a mesocyclone. The tornado typically descends from a rotating wall cloud that is located beneath the base of the storm.
What does it mean if a thunderstorm warning is issued?
A thunderstorm warning means that severe thunderstorms are expected to occur in the warned area. This can include threats of strong winds, hail, heavy rain, and lightning, which can pose dangers to life and property. It is important to take immediate precautions and seek shelter when a thunderstorm warning is issued.
What does the sky look like when a tornado is about to hit?
Contrary to what some might say, there is no particular "tornado sky" that will give you a warning. Tornadoes occur during severe thunderstorms and so will be accompanied by thick, often dark clouds. Heavy rain is often present The clouds often appear gray, as they usually do during a thunderstorm, but may become black, green, yellow, or blue. Such colors often indicate that a thunderstorm may be severe but do not necessarily mean there is potential for tornadoes. One sign that is a potential warning is a wall cloud, which is a rotating mass of cloud that hangs down from the base of the thunderstorm. This however is not always present or may be hidden by rain.
Does lightning strike in a tornado?
Yes, lightning can occur during a tornado. It is not caused by the tornado itself, but rather the severe thunderstorm that often accompanies tornadoes. Lightning is a common occurrence in thunderstorms due to the electrical charges interacting within the storm clouds.
When do tornadoes occur most frequently?

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.
