It depends on when "back then" refers to, but generally tornadoes in the late 19th and early 20th centuries were the worst because they struck without warning. Starting in the 1940s we began working on ways of studying and eventually predicting tornadoes. Over the decades, improving technology and an expanding understanding of tornadoes have given us the warning system we have now, which gives people time to get to a safe place. Additionally, the overall number of intense tornadoes, the ones responsible for the most death and destruction, appears to have declined, at least in the U.S.
That said, 2011 was a recent anomaly in which we saw the deadliest tornadoes to hit the U.S. in over 50 years. It was reminiscent of the Super Outbreak of 1974 and the devastating 1953 tornado season.
USA, Canada, Bangladesh, Great Britain, New Zealand
Most of the worst tornadoes happen in the central and southern United States, though the worst single tornado on record was in Bangladesh.
Spring is when the U.S. generally has the worst tornadoes.
The worst tornadoes in North America generally strike the central and southern United States, though several particularly destructive tornadoes have occurred in southern Canada and in New England.
Some were the Tri State Tornado, the Natchez tornado , also the Gainesville tornadoes.
This cannot be answered simply, as both hurricanes and tornadoes vary greatly in how bad they are. The impacts of both tornadoes and hurricanes can range from negligible to devastating. That said, the very worst hurricanes can be far deadlier and more destructive than the worst tornadoes.
Yes. The destruction caused by the worst tornadoes is often front page news.
It varies. Most tornadoes don't kill anyone. At their worst tornadoes can kill hundreds. The highest death toll for a single tornado is 1300
Tornadoes are called a thunderstorm's worst killer.
Right now Ahmen Green is not the best.
Overall, no. Historically Texas, especially in its northern and eastern areas, has had worse tornadoes than Nebraska, though both states have experienced very deadly and destructive tornadoes.
There are not publicly available tornado season forecasts. However, seeing as it is now late June, Kansas is probably past the worst of its tornado activity for 2013.
