Ever notice how unattended children in a car will honk the horn?
That seems to be the case with the 911 operators; they can't seem to resist the urge to run the siren. Each and every time the siren has sounded there has been no danger. After a while everyone ignores the warning. Thunderstorms tend to announce themselves rather brightly and loudly, and well in advance of their arrival. The siren does not need to be sounded because of some weather a 100 miles away that will take hours to arrive, that might turn into a thunderstorm, that could become severe, that may hit Alpena. The siren should only be sounded when there is a "Clear and Present Danger."
