NEXRAD
NOTE: The TOPO and/or TERRAIN display and NEXRAD are mutually exclusive for all applicable maps.
NEXRAD (NEXt-generation RADar) is a network of 158 high-resolution Doppler radar systems that are
operated by the National Weather Service (NWS). Its technical name is WSR-88D.
NEXRAD data provides centralized meteorological information for the continental United States and
selected overseas locations. The maximum range of a single NEXRAD radar site is 250 nautical miles. In
addition to a wide array of services, the NEXRAD network provides important information about severe
weather and air traffic safety.
NEXRAD data is not real-time. The lapsed time between collection, processing, and dissemination of
NEXRAD images can be significant and may not reflect the current radar synopsis. Due to the inherent
delays and the relative age of the data, it should be used for long-range planning purposes only. Never use
NEXRAD data or any radar data to penetrate hazardous weather. Rather, use it in an early-warning capacity
of pre-departure and enroute evaluation.
