4.7.5 NEXRAD Weather
NEXRAD (Next-Generation Radar) is a network of 159 high-resolution Doppler radars
operated by the National Weather Service (NWS) to detect meteorological data for
the United States. The data can be processed and displayed in a mosaic map showing
patterns of precipitation and its movement. Each NEXRAD radar site has a maximum
range of 250 nm. Since NEXRAD data is not real-time, data is updated about every 10
minutes not including processing and dissemination time, it should be used for long
range planning only. Do not use NEXRAD to penetrate severe weather.
Coverage is generally limited to the Continental United States, its coastal regions.,
portions of Alaska, Hawaii, Puerto Rico and Guam. The Hot Key label is green when
enabled and blue when disabled. When enabled the NXRD annunciation displays above
the current Range. The Weather default setting is OFF.
