Each disaster alert device includes a radio receiver, and a processor programmed to monitor radio transmissions from one or more central stations for disaster alerts directed to the location of the disaster alert device. Each alert device also includes an audio unit to alert personnel located at the site of the device to the precise nature of the disaster. The disaster alert devices are pre-programmed with information identifying the precise use location of the warning device. This use location information includes latitude and longitude of the use location and may also include other location information such as street address and zip code. Warnings are broadcast from central stations identifying location information specific at-risk regions to which the warnings are directed which could be, for example, nationwide, statewide, countywide, a single street or a single residence.
