A method and system for correlating the performance of at least one cellular coverage area with external impact events. The method can include receiving and storing performance data for the cellular coverage area. The method can also include receiving and storing a national weather service (NWS) weather alert for a geographic area near the cellular coverage area. The weather alert indicates a severe weather condition. The method further includes extracting and storing geographic coordinates, alert type, and alert time data from the NWS weather alert, and generating an output indicative of relationships between the performance of the cellular coverage area and the severe weather condition.
