Computer 32 determines a plurality of routes, each for one of a specified plurality of ground vehicles 34, upon receipt of a command to broadcast an alert. The computer instructs each ground vehicle to follow its respective route while playing a message from external speakers 36. The computer may receive data from the ground vehicles about an external environment which includes at least one of video, wind speed, wind direction, and traffic density. The plurality of ground vehicles may be selected from a plurality of eligible ground vehicles. The computer may instruct a plurality of stationary sirens 38 to activate, with the routes based on a coverage area of the stationary sirens. The routes may be based on population density, substantially equalizing coverage of a forecast emergency area by the ground vehicles, the driving ranges of the ground vehicles, or areas experiencing power outages.
