When will the outdoor warning sirens sound?
The City of Waco tests the sirens on the first Friday of each month at 10 a.m. If you hear the sirens at any other time, there is the possibility of a weather-related or other emergency that could require you to take precautions. For weather-related emergencies, the City of Waco will activate the sirens during a tornado warning if a tornado is imminent.
