(KMOV) – News 4 is hearing from a number of our viewers about tornado sirens going off around St. Louis County.
Those sirens are false alarms.
As we first reported on Monday night at 10, there is a malfunction in the St. Louis County system.
On Tuesday, engineers are setting off the sirens on purpose in an attempt to identify the problem.
The county is also about to put a new system in place. That system should be ready for next year.
