Which intensity of precipitation is not shown to en route controllers on the WARP/NEXRAD display?

The intensity of precipitation displayed on the WARP/NEXRAD system for en route controllers typically includes categories such as light, moderate, severe, and heavy. However, light precipitation intensity is not represented on the en route radar display for controllers.

This is primarily due to the operational focus of en route controllers, who are responsible for managing aircraft in the en route phase of flight, where monitoring significant weather phenomena that could impact flight safety and efficiency is crucial. Light precipitation, while present, does not usually pose a significant threat to flight operations, making it less relevant for immediate air traffic management.

By omitting light precipitation from the display, en route controllers can concentrate on more impactful weather conditions that require their attention and may necessitate adjustments in flight paths for safety. This focus ensures that controllers can maintain situational awareness around heavier weather activities while applying resources effectively to manage air traffic safely.
