An improved avionics display unit graphically presents meteorological phenomena data to a pilot enroute utilizing conventional pilot report (PIREP) information which includes meteorological phenomena data including phenomena location data. The avionics display unit generates an icon defined by the meteorological phenomena data of the PIREP information and presents the icon on a display of the avionics display unit overlaying a map display at an icon location determined in response to the phenomena location data of the PIREP information.
