How much warning in advance are people today given for an approaching large tornado?

It varies considerably. Warnings for major tornado may have a better lead time than averages because the signature is usually easier to detect on radar. Lead time is often 15 to 20 minutes. This can include time before the tornado touches down.
However, there is quite a bit of variability. Greensburg Kansas, which was hit by an EF5 tornado in 2007, had 39 minutes warning. By contrast, Cincinnati, Arkansas, which was hit by an EF3 tornado in 2010, had no warning.
If you only consider the time after the tornado has touched down, lead times can be shorter, as sometimes a tornado will develop just outside a town, leaving little time to update warnings. In the case of Joplin, Missouri in 2011, the tornado touched down less than a mile outside of town and entered the city two minutes later. A tornado warning has been in effect for 17 minutes before the tornado formed, warning of the potential for a tornado.

Were people prepared for the tri state tornado?
No. Back in 1925, when this tornado ocurred, there were no tornado waatches or warnings. In fact, meterologists were forbidden to mention tornadoes in their forecasts for fear of starting a panic. As a result, the Tri-State tornado struck without warning. Because of the wide funnel and low cloud base, many people who saw it approaching did not even realize it was a tornado.

How did people protect themselves from the Greensburg tornado?
The National Weather Service was aware of the tornado well in advance and issued a tornado warning in Greensburg 39 minutes before it was hit and a tornado emergency 12 minutes before. The people of Greensburg responded accordingly by seeking shelter in their basements and interior rooms, giving them as much shelter as they could get.
How close does a tornado have to be to issue a warning?
A tornado warning is when someone has seen a funnel cloud or when a tornado touchdown has been reported. A tornado warning is in play for the people near, or remotely near, or even right next to the tornadic activity area. I agree, but when they give out a warning, it is most likely they'll do it by county.

Why did the most deadly tornadoes happen in the past?
Most extremely deadly tornadoes happened in the first half of the twentieth century or earlier because there was no warning system. People rarely knew a tornado was coming unless they could see or hear ait, and by that time it was often too late to take cover. Nowadays most tornadoes prompt a warning at least a few minutes in advance, giving people a chance to get to safety. On May 3, 1999 an F5 tornado tore through the Oklahoma City area. The tornado killed 36 people, but it is estimated that advance warning saved as many as 600 lives.
How long does it take scientist to warn people that a tornado is coming?

Was there a severe weather warning for the Rock Springs tornado?
No. We did not have a warning system back when the tornado hit in 1927. People in nearby towns were not even aware the tornado had occurred until some time after.
Why is it easier to prepare for a hurricane than a tornado?
Hurricanes are large-scale systems that can be detected and tracked days before the strike, giving plenty of time for most people to prepare. A hurricane warning may be issued up to 36 hours in advance. Tornadoes are very small-scale storms that are less easily detected and develop in a matter of minutes. The average tornado warning is issued 14 minutes in advance.
