When severe weather strikes, there's another way for people in Nashville to stay informed. The city has upgraded its system of tornado sirens by adding 20 more.
Metro officials have increased the number of sirens in Davidson County from 73 to 93 in the past couple months.
The sirens' sound has also changed from an electronic tone to a mechanically-generated one similar to an old-fashioned air-raid warning.
"I think it's going to sound more like 'danger.' The electronic tone is loud, but it doesn't associate with danger," said Scott Potter, with Metro Emergency Operations.
The city said the different tone will also make it easier to hear and travel a greater distance.
The purpose of the tornado warning siren system is to provide emergency weather alerts to those in outdoor settings when a tornado warning had been issued.
"This is something we've long wanted, and I'm very excited Mayor Dean is making it happen," said Metro Councilwoman Karen Johnson.
The estimated cost of the upgrade is $2 million, which will be paid for by a capital bond program approved by the Metro Council in 2012.
