Insurance Journal reported last week on a bill sponsored by Representative Jim Bridenstine (R-Oklahoma). In a fit of poor reporting, the author says the bill makes the “protection of people and property a priority.” Unfortunately, the National Weather Service mission statement has included “protection of life and property” for years. The bill itself contains no such insulting verbiage. On the surface, it’s actually a welcome relief: a Congressman looking to direct over half a billion dollars of new funding to scientific research and operations. In reality, it strikes me as more of a pipe dream.
The average tornado warning lead time is currently around 13 minutes. The goal of Bridenstine’s bill is a lead time of 60 minutes or more. Stretch goals are good, but a 4x increase is not, perhaps, the most appropriate for legislation. Even so, there’s a question of how valuable such an increase would really be. Increased protection of property is probably not going to be that dramatic with hour-long lead times. It’s not like people can move their houses and businesses out of the way. Some damage could be prevented by securing loose objects and boarding windows, but it’s not likely to be significant.
Protecting life is the more important aspect, but would a one-hour lead time help? I’ve argued for years that there’s definitely an upper bound to lead times after which the returns diminish. My suspicion is that as the lead time grows beyond that point, people become more and more complacent. This argument has been based on hunches and unsubstantiated reasoning. It turns out, there’s evidence that increased lead time has no impact on injuries from tornadoes.
Even if the benefits are minimal, the amount of learning that would have to take place to get lead times up to an hour would aid our understanding of severe weather. The improvements to observation networks and modeling would benefit all areas of weather forecasting. Even if tornado warning lead times remain unchanged, the scientific impact of this bill would be dramatic. I just worry that it’s setting the National Weather Service up for “failure”.
