During Washington hearing, weather experts question focus on more lead time for tornadoes

At Capitol Hill hearing, University of Oklahoma weather researcher says focus should be on zero deaths rather than a “magical number” of how much lead time to provide people to get to safety

— Citing the chaos in central Oklahoma last month when people tried to flee from dangerous storms in their cars, a weather expert from the University of Oklahoma said here Wednesday that research on storm warnings should include an examination of how people respond to them.

Kelvin Droegemeier, a professor of meteorology and a researcher at OU's National Weather Center, told a House subcommittee that lawmakers should be cautious in focusing on reaching the goal of providing an hour of lead time to people about potential tornadoes.

“We need to understand how we convey and formulate uncertainty in messaging to the public, how the public responds and comprehends warning information,” Droegemeier told a Science, Space and Technology subcommittee.

“And I think that we have to even ask ourselves whether the whole current watch and warning system really needs to be rethought from the ground up starting with people, because the people are the ones who are affected ultimately.”

The researcher's comments came during a hearing on legislation by Rep. Jim Bridenstine, R-Tulsa, that would boost funding for weather research and make it a higher priority for the federal government. The bill creates a program to “develop and extend accurate tornado forecasts and warnings beyond one hour in order to reduce loss of life, injury, and damage to the economy.”

Droegemeier said it was important to look at the lead time.

“But I think we want to be careful about not focusing entirely on that magical number because ultimately the question is ... what are people going to do with that one hour?”

On May 31 in central Oklahoma, he said, thousands of people fled their homes and “put themselves in harm's way because they had a very large amount of lead time without really knowing what to do with it ... And so I would argue that our focus really should be on the goal of zero deaths.”
