NASHVILLE, Tenn.- Metro's Office of Emergency Management announced Thursday a new tornado siren policy designed to save lives during severe weather.
When the National Weather Service issues a tornado warning for Davidson County, OEM will activate all 70 sirens across the county simultaneously.
They will sound continuously for three minutes and repeat in eight-minute intervals.
Officials said the policy will help alert those who are unaware of dangerous weather conditions.
"This policy was created to provide our citizens with an additional layer of notification that severe weather is imminent and shelter should be sought immediately," said Acting Director Stephen Halford in a news release.
"By sounding the sirens more than once, we increase the safety of our vulnerable citizens who may be outdoors away from a television or radio," Halford said.
The new policy was put into action for the first time last week as severe weather and deadly tornados ripped across the state.
The weather service issued six tornado warnings for Davidson County on Feb. 5 and Feb. 6 when the siren system was activated 25 times, according to OEM.
