Not very far. The average lead time for a tornado warning is 14 minutes. However, the potential for tornadoes across a region can be forecast several days in advance.
Tornado sirens or alarms are designed so that they can be heard at least five miles away. Tornado sirens are placed in cities and towns and rural areas so that people can be warned well in advance of a tornado.
It is impossible to make such predictions for any specific location a day in advance; such predictions can only be made on a time scale of minutes. For the tornado outbreak of April 9, 2015, tornadoes were reported not far from Peoria, but it does not appear that Peoria itself was hit.
No. Supercomputers are used to run forecast models, which are used for longer time frames of hours to days. Such models can predict that tornado activity may occur across a region on a given day, but cannot predict where or when individual tornado will form. Down to the minute forecasts are made using Doppler radar images and, in some cases, eyewitness reports. Human meteorologists then judge, based on this information, whether a tornado warning is warranted. Computer forecast models are useless in these scenarios, as they take too long to run.
No one can predict exactly when an area will have a tornado far in the future and therefore no one knows.
No. The Titanic was far too massive to be lifted even by the most violent tornado.
A long term forecast could be good for about 2.5 months.
it takes about four hours

It is not known. It is impossible to predict a tornado for a specific location until it actually occurs. Regional tornado potential can be predicted up to a few days in advance, but even then there is a lot of uncertainty. A forecast could say tornadoes are likely, but cannot say for certain if a tornado will touch down in a particular area such as central Louisiana. As of August 22, 2013 there is little to no tornado potential in the southern United States for the next few days.
It is impossible to catch a tornado. However, using a combination of forecast models and Doppler radar it is possible to predict where a tornado might occur. Scientists will try to use this information to find a tornado and study it.
The first tornado forecast ocurred on March 25, 1948. Air Force meteorologists at Tinker Air Force Base in Oklhoma City noticed that weather conditions were very similar to those that had produced tornadoes earlier in the week. Not long afterward an F3 tornado struck the base, destroying numerous planes and several hangars.
Hurricanes often begin as disturbances off the coast of Africa.
Key words for tornadoes include eye, barometric pressure, funnel cloud and forecast. Additional key words include supercell, tornado alley, tornado watch, tornado warning, vortex and counterclockwise.
Tornadoes cannot be predicted so far in advance. The only way you can know that a town or city will likely be hit, is if the tornado is already on the ground and heading toward that community. The chances of a given location being hit byt a tornado on any given day, though, are quite small.
The hardest tornado was in Texas, USA.
