1. A method for automatic event notification in a radio communication system having a plurality of geographically dispersed transmitters, comprising the steps of:
- receiving weather information and corresponding locality information broadcasted from weather a data source;
receiving a weather location code from the weather data source as part of the locality information; and
querying a database, which database maps weather location codes to corresponding transmitter locations, for a transmitter location using the weather location code as a search criteria;

Abstract
A subscriber (125) to a radio communication system (110) is automatically notified of an event affecting or potential affecting a particular geographical locality. The radio communication system obtains such event and locality information (310, 320), and uses the locality information to transmit the event information to subscribers of that system potentially affected by the event. In one embodiment, the system automatically uses only transmitters that service at least a portion of the affected locality to transmit the event information (330, 340). In another embodiment, the system automatically transmits event information selectively to those subscribers having a location designation corresponding to the particular locality (410, 420).
