ST. LOUIS (KMOV) -- Don’t be alarmed if you happen to hear sirens in your neighborhood next week, as St. Louis County will be conducting a number of tests on several emergency sirens throughout the area.
Officials say the county will test 24 sirens at random every day next week between 10 a.m. and 2 p.m.
During the most recent regularly-scheduled test earlier this month, residents around those 24 sirens said they had a hard time hearing them.
“We’ll run multiple tests from different directions, checking decibels in different distance from each siren,” said David Wrone with St. Louis County Public Works. “It matters if you have tall buildings or open space. So that affects the specific testing.”
The tests will last only one minute. In a real tornado emergency, the sirens sound continuously for three minutes.
