    Interface Airmet

    A parsed AIRMET (Airman's Meteorological Information) bulletin.

    AIRMETs are in-flight weather advisories for conditions potentially hazardous to all aircraft, particularly light aircraft. They are issued as bulletins containing one or more hazard areas, organized by series:

    • Sierra - IFR and mountain obscuration
    • Tango - Turbulence, strong surface winds, and low-level wind shear
    • Zulu - Icing and freezing level
    import { parseAirmet } from '@squawk/weather';

    const airmet = parseAirmet(rawBulletin);
    console.log(airmet.series, airmet.hazards.length);
    for (const hazard of airmet.hazards) {
      console.log(hazard.hazardType, hazard.states, hazard.conditionDescription);
    }
    interface Airmet {
        freezingLevel?: AirmetFreezingLevel;
        hazards: AirmetHazard[];
