HAZARD AVOIDANCE
NOTE: WSR-88D weather surveillance radar or NEXRAD (NEXt generation RADar) is a Doppler radar system
that has improved the detection of meteorological events such as thunderstorms, tornadoes, and hurricanes.
An extensive network of NEXRAD stations provides almost complete radar coverage of the continental
United States, Alaska, and Hawaii. The unobstructed range of each NEXRAD is 124 nautical miles.
The following elements may cause abnormalities in the displayed NEXRAD images:
• Ground Clutter
• Strobes and spurious radar data
• Sun strobes, when the radar antenna points
directly at the sun
• Interference from buildings or mountains,
which may cause shadows
• Military aircraft deploying metallic dust which
can cause alterations in radar scans
