This year may set records for tornadoes and tornado-related deaths. “We have already seen more than 115 tornado-related deaths, making this the deadliest tornado season since 1998,” said a meteorologist at NOAA’s Storm Prediction Center. “It is only the third time since the 1974 super tornado outbreak that there have been more than 100 tornado-related deaths during a single tornado season in the U.S.,” a research meteorologist at NOAA’s National Severe Storms Laboratory added.
