    Interface NonConvectiveSigmet

    A parsed domestic non-convective SIGMET for the CONUS.

    Non-convective SIGMETs are issued for severe turbulence, severe icing, widespread dust/sandstorms, and volcanic ash. They are valid for up to 4 hours and are reissued as needed. A single SIGMET may contain multiple hazard descriptions.

    Properties

    areaPoints?: string[]

    Area definition points delineating the affected region (VOR-relative, e.g. "30NW SLC", "60SE BOI").

    ashCloudAltitudeRange?: AltitudeRange

    Altitude range of the observed volcanic ash cloud.

    cancellationReason?: string

    Reason text for the cancellation (e.g. "CONDS MSTLY MOD", "CONDS HV ENDED").

    cancelledSeriesName?: SigmetSeriesName

    Series name of the SIGMET being cancelled (when isCancellation is true).

    cancelledSeriesNumber?: number

    Series number of the SIGMET being cancelled (when isCancellation is true).

    conditionsContinuingBeyond?: DayTime

    Time (UTC) beyond which conditions are expected to continue.

    conditionsEndingBy?: DayTime

    Time (UTC) by which conditions are expected to end.

    forecastAltitudeRange?: AltitudeRange

    Forecast altitude range of the volcanic ash cloud.

    forecastTime?: DayTime

    Forecast time (UTC) for volcanic ash cloud position.

    format: "NONCONVECTIVE"

    Discriminator indicating this is a non-convective SIGMET.

    hazards: SigmetHazard[]

    Weather hazards described in this SIGMET. Multiple hazards may be present in a single SIGMET.

    intensityChange?: SigmetIntensityChange

    Trend in intensity of the phenomena.

    isCancellation: boolean

    True when this SIGMET cancels a previously issued SIGMET.

    movement?: SigmetMovement

    Movement of the hazard area.

    raw: string

    The original raw SIGMET string as provided to the parser.

    seriesName: SigmetSeriesName

    NATO phonetic series name (e.g. NOVEMBER, OSCAR, PAPA).

    seriesNumber: number

    Sequence number within the series.

    states?: string[]

    US state abbreviations and area codes affected by the phenomena.

    validUntil?: DayTime

    Time (UTC) until which this SIGMET is valid.

    volcanoName?: string

    Name of the volcano for volcanic ash SIGMETs (e.g. "MT REDOUBT").

    volcanoPosition?: Coordinates

    Geographic position of the volcano.
