SIGMETS AND AIRMETS
SIGMETs (SIGnificant METeorological Information) and AIRMETs (AIRmen' s METeorological Information)
are issued for potentially hazardous weather. A Convective SIGMET is issued for hazardous convective
weather such as severe or widespread thunderstorms. A localized SIGMET can be displayed when significant
weather conditions are not widespread.
The entire SIGMET or AIRMET is displayed as long as any portion of it is issued within the coverage area
of the GFDS data request.
