A system, method, and computer program product for alerting a flight crew of weather radar return data collected, yet not presently being displayed. The system includes a memory, a processor, and an output device. The memory stores radar return information in a three-dimensional buffer. The processor determines if any radar return information stored in a three-dimensional buffer is within a threshold distance from an aircraft's present position and generates an image based on target data stored in the three-dimensional buffer and selected display parameters. The processor also generates a target alert if any target data is determined to be within a threshold distance from the aircraft's present position and is not included in the generated image. The output device presents the generated target alert.
