The city of Greenbrier is looking for a more cost effective and reliable way to alert residents of severe weather.Mayor Billy Wilson told Nashville's News 2 that during the most recent round of bad weather, he was unable to hear the city's tornado siren."So I'm right there, I pass one of these sirens during this tornado warning and I never heard a siren anywhere, so if I didn't hear it, people didn't hear it," he said.Mayor Wilson has formed a committee of alderman along with the city superintendent to review the old weather alert system."I just felt it was time to look at other ways to alert people," said Wilson, who also serves as a volunteer firefighter and was working the night of the storm.The committee will examine new technology that will alert more residents than the traditional tornado sirens that only serve limited parts of the city. "It just depends on the way the wind's blowing," he added.Mayor Wilson said that one option is to provide every Greenbrier resident with a free weather radio."Taxpayer dollars would pay for that siren, taxpayer dollars... for senior citizens, people who cannot afford that, should be provided by the city," he told Nashville's News 2.The board will review costs for efficiency for each option and report back to the committee.
