AIR/SIGMET

An AIRMET advises of weather that may be hazardous (other than convective activity) to aircraft, but are less severe than SIGMETs. This information is used by end-users that are directly related to aviation flight planning and safety of flight, including pilots and personnel who provide weather information to pilots. AIRMETs are regularly scheduled text messages containing a 6 hour forecast with a 6 to 12 hour outlook period. This results in a "time-smear" over which the condition(s) may exist. AIRMETs are issued by the NWS's AWC (for the lower 48 states and adjacent coastal waters).
