Abstract: Lightning and thunderstorm are the most significant cause of interferences in the transmission and electrical power distribution systems. All terrestrial based electrical systems; telecommunication exchanges stations, global system for mobile communications (GSM) base stations as well as tall structures are prone to disruptive forces of lightning strikes. The intent of this study is to look at the available data for the development of a map on the thunderstorm day and flash density and to determine the area that are prone to high/low risk of thunderstorm/lightning in the northeast zone of Nigeria. This was done in order to give insight into the risks associated with the thunderstorm on electrical equipment in relation to the locations in the region. The data information for more than twenty years about this region was collected from the Nigeria Meteorological Service (NMS) for the analysis of the thunderstorm day level.
