    Interface WindsAloftLevel

    Wind and optional temperature forecast at a single altitude for a single station.

    Light-and-variable winds (raw code "9900") are flagged via isLightAndVariable with directionDeg and speedKt left undefined, because the underlying product only indicates "< 5 kt, variable direction" - it does not commit to a specific value.

    Missing entries (where the station is too low or too high for the altitude column) are flagged via isMissing with all data fields left undefined.

    interface WindsAloftLevel {
        altitudeFt: number;
        directionDeg?: number;
        isLightAndVariable: boolean;
        isMissing: boolean;
        speedKt?: number;
        temperatureC?: number;
    }
