Johnson County’s outdoor warning system consists of 184 sirens placed strategically throughout the county as an early warning device to alert citizens of potential danger. While the outdoor warning system is an effective method of notifying those outdoors, it is only one component of a comprehensive emergency warning system including the use of NOAA Weather radios, the Emergency Alert System, and emergency notifications from local media.
Sirens are designed as an outdoor warning system, and should not be relied upon to provide sufficient warning indoors or in noisy areas. Air-conditioning, thunder, wind, rain, and other conditions may cause the sirens not to be heard indoors or outdoors (even if sirens can be heard during tests). Sirens are also subject to lightning strikes and other equipment malfunction. Furthermore, sirens provide no information on the type of threat or exact location of potential danger. For this reason, if you hear the sirens, you should seek shelter immediately.
Individuals, families, and businesses are strongly encouraged to use NOAA weather radios to receive warnings and emergency information. Through Project Community Alert, an initiative of the Metropolitan Emergency Managers Committee, these radios are being sold at $29.95, a considerable savings over the regular price, at metro area Price Chopper stores.
