What types of weather conditions do SIGMETs provide warnings for?

SIGMETs, or Significant Meteorological Information, are critical weather advisories that are issued to inform all aircraft about significant weather phenomena that may affect their safety during flight operations. These advisories cover a range of severe weather conditions, including thunderstorms, turbulence, icing, volcanic ash, and dust storms.

Since SIGMETs are intended for all types of aircraft—regardless of their size or mission—their information is crucial for ensuring the safety of commercial, general aviation, and private flights alike. The warnings provided by SIGMETs help pilots make informed decisions about routes, altitudes, and other operational parameters in the face of potentially hazardous weather conditions. This comprehensive approach ensures that all pilots receive the necessary information to navigate safely, thus emphasizing the importance of SIGMETs as a universal safety tool in aviation meteorology.
