Outdoor sirens are an outside-warning tool
Springfield-Greene County emergency guidance explains when outdoor warning sirens may sound, but residents still need direct weather alerts.
Outdoor warning sirens are built for people who are outside, not as the whole household alert plan. Greene County and Springfield share emergency-management tools, and sirens can sound for triggers such as a National Weather Service tornado warning for the warned area, a trained spotter report, or a thunderstorm warning with life-threatening winds.
The better habit is to treat a siren as one layer. Indoors, you may not hear it well, and a phone alert or weather radio can give more direct notice. A tornado watch means conditions could produce a tornado. A tornado warning means danger is closer and it is time to move to an interior room on the lowest floor.
Do not spend storm minutes sorting out policy language. Have more than one alert, and know where the safer room is before the sky gets loud.
