Combined NEXRAD
Regional NEXRAD data and CONUS NEXRAD data are shown together. The
two types of NEXRAD are separated by a white stippled border. This boundary
is updated whenever new Regional or CONUS NEXRAD data is received. The
radius of the boundary is fixed at 150 NM.

4.11.5.5 SIGMETs and AIRMETs (SIG/AIR)
SIGMETs (SIGnificant METeorological Information) and AIRMETs
(AIRmen’s METeorological Information) are broadcast for potentially hazardous
weather considered of importance to aircraft. A Convective SIGMET is issued
for hazardous convective weather. A localized SIGMET is a significant weather
condition occurring at a localized geographical position.
When enabled, SIGMET/AIRMETs advise the pilot of potentially hazardous
weather to all aircraft. SIGMET/AIRMET data covers icing, turbulence, dust,
and volcanic ash as issued by the National Weather Service. The update rate is
every 12 minutes.
