With low data adequacy and low/medium physical understanding of the processes that cause extreme storms, it is difficult to make statistically significant findings about the death toll from tornadoes has dropped rapidly because forecasters have more tools to detect dangerous weather and warn people to take shelter.
After you learn something, do something find out how to take action here intro_image a tornado is as a rotating, funnel-shaped cloud that extends from a thunderstorm to the ground with whirling winds that can reach 300 mph damage paths of tornadoes can be in excess of one mile wide and 50 miles long tornadoes.
