SIGnificant METeorological advisories knows as SIGMETs contain important meteorological information that can impact the safety of all aircraft. There are 2 broad categories of SIGMETS, Convective and Non-Convective. Convective SIGMETs are issued for areas of atmospheric convection which may produce thunderstorms or severe surface weather. Non-Convective SIGMETs are often issued for areas of turbulence, severe icing or other dangerous atmospheric conditions such as volcanic ash. If you are flying thru an active SIGMET the chance of turbulence is increased.
