A method is presented for providing information associated with a geographical area to users of broadcast communication receivers. The information, as well as an indication of the geographical area associated with the information, are transmitted to, and received by, each of the broadcast communication receivers. In each of the receivers, the indication of the geographical area is compared with a geographic code associated with, and stored within, the receiver. Each of the receivers also provides at least one alert to a user of the respective broadcast communication receiver if the geographic area is located on a travel vector of the respective broadcast communication receiver indicated by the geographical code.
