Jefferson County Siren Locator Map
Welcome to the interactive map showing the locations of the outdoor warning sirens managed by the Jefferson County EMA. To find the siren nearest you, simply input your location in the search bar and hit "enter" and you'll be taken to that address. From there, you can scroll or zoom to locate the siren closest to that address.
Please remember, although sirens may have a maximum audible range of about a mile and a half, that range is definitively smaller once you add in terrain, trees, buildings, traffic, wind, rain, thunder, etc. Do not rely solely on these sirens as your only means of emergency notification. Please have a NOAA weather radio, smartphone app, and other methods to receive emergency alerts like our very own Everbridge Emergency Alert system.
