A system and method for generating storm warnings which are precisely tailored automatically for a particular individual or business user's geographic location of interest, which may be provided automatically to the individual user or business. The user establishes an individualized user profile, in which the user may define a particular location of interest and a contact address to which a personalized storm warning is to be delivered. The user may also establish a storm profile defining attribute characteristics of a storm for which the user desires a storm warning to be provided, and an amount of advanced warning to be provided by the personalized storm warning. A detailed and accurate storm track which includes information describing storm characteristics (severe weather conditions) as well as the current location and predicted track of movement of storm, is generated. The storm track may be generated automatically from weather radar data, such as NEXRAD data, either alone, or in combination with local live weather radar information, to provide a more accurate storm track.
