"Close to half of the spotter reports are from ham radio operators, so they really are the backbone. The rest comes from law enforcement with some reports from the public," Tucek said. "Communication is the key to public safety."
It was amateur radio operators who first spotted signs of a potential tornado over Terre Haute heading toward Indianapolis last May 30. Storms combined to create 23 tornadoes on that day, largely in central Indiana, for the second largest tornado outbreak in state history, causing one fatality in Crawford County from lightning, Tucek said.
"We average about 20 tornadoes per year, so that was a big day for Indiana," Tucek said.
During those storms last May, 98 percent of the storm warnings sent out from the National Weather Service came from information obtained from amateur radio weather spotters, Tucek said.
