SIGMETs
noun
1. Like PIREPs, SIGMETs is a combination of Significant Meteorlogical hazards, which are inflight weather advisories for pilots covering a certain area. These serve as alerts for things such as convection (thunderstorms), turbulence, icing, and visibility, and can be viewed on aviationweather.gov. Look for TURB or CONV sigmets as indicators of potentially bumpy/turbulent areas of your flight, and plan your beverage orders accordingly.
