Nineteen of the twenty deadliest tornadoes occurred before 1960. This in spite of the fact that population density was much lower, and that they didn’t have superstores like Home Depot and Wal Mart with hundreds of people in one place.
The US Weather Service (Ministry of Truth) issued this statement in May :
The death toll so far this year stands at 520. The previous highest recorded death toll in a single year was 519 in 1953.
The Weather Service lacks access to the Internet and apparently was unable to spend ten seconds or so searching Google before making that statement.
