St. Louis County, Mo (KSDK) -- Twenty-four St. Louis County tornado sirens will be tested next week to determine if they are loud enough.

The one-minute tests will be performed between 10 a.m. and 2 p.m. April 16-20.  An announcement that "This is only a test" will be made prior to a device being tested.

Each of the two dozen sirens generated multiple calls following the regular, first-Monday-of-the-month siren tests conducted this year, according to the St. Louis County Departments of Highway and Traffic and Public Works.  Residents reported that they were unable to hear the sirens, whereas under the old system, they could be heard.

In an actual emergency, the sirens would wail continuously for three minutes. Their activation serves as an alert that a tornado or tornadoes are approaching the region - and that residents need to immediately take cover.

The exception to this is the first Monday of every month, at 11 a.m., at which date and time the sirens are tested.

The tornado warning system - the installation of which was overseen by the County's Emergency Communications Commission - was paid for by an emergency communications sales tax approved by voters in 2009. It was activated last Labor Day Weekend (September 2011).
