identifies deceptively strong or unknown intensity parts of a storm. While in horizontal
scan mode, this feature can be used as a tool to determine areas of possible inaccuracies in displayed
intensity due to weakening of the radar energy. This weakening is known as attenuation. The radar energy
weakens as it passes through areas of intense precipitation, large areas of lesser precipitation, and distance.
Issues with the radome also attenuates the radar energy. All these factors have an effect on the return
intensity. The more energy that dissipates, the lesser the displayed intensity of the return. Accuracy of the
displayed intensity of returns located in the shaded areas are suspect. Make maneuvering decisions with
this information in mind. Proper antenna tilt management should still be employed to determine the extent
of attenuation in a shaded area.
To activate or deactivate the WATCH
