There has been much talk recently about Lubbock installing tornado sirens.
In very small towns, these tornado sirens can be very helpful in alerting the citizens to take shelter. However, in larger cities such as Lubbock, these sirens would benefit only a very small percentage of the population.
Few people have their windows open, especially during a thunderstorm and thus would not be able to hear the sirens unless they lived very close to the siren location.
