AIRMET (Airmen's Meteorological Information)
An in-flight weather advisory for conditions that may affect aircraft operations but are less severe than SIGMET criteria, such as moderate icing or turbulence, mountain obscuration, or widespread IFR. Modern briefings commonly present these as G-AIRMETs (graphical AIRMETs).
