Most tornadoes form within a larger circulation called a mesocyclone that usually exists for some time before a tornado forms. Doppler radar can detect this rotation, and warnings issued baded on that. The cicruclation of the tornado itself may also be detected before it touches down. Warnings can then be issued through TV and radio broadcasts, online outlets, smartphone apps, and, in some towns, sirens.
Yes. Tornado warnings are commonplace in the United States, with an average lead time of 14 minutes.
A tornado warned storm is a thunderstorm for which a tornado warning has been issued, meaning that the storm is producing rotation that can spawn a tornado.
Storm spotters can help tell exactly were a tornado is and where it is going, so people in the path can be warned and get to safety.
A tornado warned storm is a thunderstorm for which a tornado warning has been issued, indicating that it is capable of producing a tornado. A tornado threat is a general term that refers to the danger tornadoes may pose to an area during a particular storm.
They didn't prepare. Waco was never warned about the approaching tornado, which was obscured by rain. As a result, nobody knew it was coming.
In developed nations such as the U.S. yes. Tornado warnings are broadcast through television, radio, the internet, and some smartphone apps. In some towns sirens will sound during a tornado warning.
Warned has no prefixes or suffixes.
Yes. Usually this happens if you are rude or offensive to other people, if you are warned and then continue to do whatever you were warned for, or if you are spamming or vandalizing the site.
Yes, though circumstances still led to some being caught off guard. The City of Joplin was under a tornado warning for 17 minutes before the tornado actually formed, so residents were told of a thunderstorm with the potential to produce a tornado. When the tornado actually touched down, it was only a mile outside of Joplin and was causing damage in the city only two minutes later. While the warning was updated accordingly, it gave little time for the people on the west side of Joplin.
Both, it seems. God has warned people, throughout history, to worship only Him and stay away from evil. We are not doing it.
Usually a watch is issued first, and then warnings are issued as tornadic storms develop. However, occasionally a tornado warned storm may develop without a tornado watch.
Move into a room, or better, a small space with no windows or glass as fast as you can. But more than likely you'll be warned with tornado sirens beforehand.
