St. Louis County, Mo (KSDK) -- St. Louis County's retesting of its new tornado sirens will begin February 1 and will continue through February 8. Tests will not be conducted on Saturday or Sunday.
The testing originally scheduled for last week was cancelled because of poor weather conditions.
The tests were spurred by possible sound coverage gaps reported during a previous tornado warning, according to St. Louis County Department of Highways and Traffic and Public Works Public Information Manager David Wrone.
The tests will be performed on individual sirens located in St. Ann, Kirkwood and Wildwood.
A scheduled date for the retesting has not been announced.
The tests are part of St. Louis County's Emergency Communications Network's ongoing tweaking of its new 187-siren tornado warning system, which started last Labor Day.
