ICAO Location indicator and name of FIR 8. Forecast position 3. Observation or forecast time 4. Location 5. Vertical level and extent 7. Change in intensity 2. Name and location of volcano

3 In issuing SIGMET for tropical cyclones or volcanic ash, the MWOs should include as appropriate the advisory information received from the responsible TCAC or VAAC. (REGIONAL SIGMET GUIDE) Example of Text VA Advisory FVFE01 RJTD VA ADVISORY DTG: /1539Z VAAC: TOKYO VOLCANO: SUWANOSEJIMA PSN: N2938 E12943 AREA: JAPAN SUMMIT ELEV: 796M ADVISORY NR: 2016/23 INFO SOURCE: HIMAWARI-8 JMA AVIATION COLOUR CODE: NIL ERUPTION DETAILS: ERUPTED AT /1418Z FL070 EXTD SE OBS VA DTG: 26/1510Z OBS VA CLD: SFC/FL070 N2941 E N2934 E N2934 E N2941 E12959 MOV E 20KT FCST VA CLD +6 HR: 26/2110Z SFC/FL070 N2902 E N2950 E N2952 E N2814 E N2811 E13029 FCST VA CLD +12 HR: 27/0310Z SFC/FL070 N3024 E N3037 E N2723 E N2711 E N2737 E13110 FCST VA CLD +18 HR: NO VA EXP RMK: NIL NXT ADVISORY: /1800Z= Name of volcano Position of volcano Observation time Observed location of volcanic ash cloud Forecast VA cloud location (+6h)

4 The main body of a WV SIGMET message consists of: 1. the ICAO location indicator of the ATS unit serving the FIR to which the SIGMET refers and the name of the FIR; 2. the Name and location of the volcano and/or an indicator for VA cloud; 3. Observation or Forecast information; 4. Location; 5. Vertical level and extent; 6. Movement or Expected movement; 7. Expected change in intensity; and 8. Forecast position of VA cloud at the end of the SIGMET validity period.

5 1. ICAO location indicator of the ATS unit serving the FIR to which the SIGMET refers and Name of the FIR e.g. RPHI Manila FIR

6 2. Name and location of volcano and/or an indicator for VA cloud (1) If the erupting volcano is known and named: [VA ERUPTION] [MT] [nnnnnnnnnn] [PSN Nnn[nn] or Snn[nn] Ennn[nn] or Wnnn[nn]] VA CLD e.g. VA ERUPTION MT BULUSAN PSN N1246 E12403 VA CLD (2) If the location of the eruption is known but un named: VA ERUPTION PSN <lat,lon> VA CLD e.g. VA ERUPTION PSN N5403 E15927 VA CLD (3) If the source of the volcanic ash is uncertain: VA CLD VA : Glossary volcanic MT : mountain PSN : position CLD : cloud

7 3. Observation or Forecast information OBS AT GGggZ e.g. OBS AT 1850Z FCST AT GGggZ e.g. FCST AT 0530Z OBS : observed FCST : forecast The observation time is based on the source of the observation (satellite image, special air-report, report from a volcano observing station, etc.)

8 4. Location Notes Main Body (WV SIGMET) (1) An area of the FIR defined by a polygon. WI <N or E or S or W>nn[nn] <N or E or S or W>nn[nn] <N or E or S or W>nn[nn] e.g. WI N6030 E02030 N6500 E02300 N5900 E02600 N6030 E02030 The end point should be a repeat of the start point to explicitly close the polygon. (REGIONAL SIGMET GUIDE) The points of a polygon '... should be kept to a minimum and should not normally exceed seven'. (ICAO ANNEX 3) The points of a polygon are provided in a 'clockwise' sense. This assists automated systems in determining the 'inside' of polygons. (REGIONAL SIGMET GUIDE) WI : within 1 WI... 2 FIR Hexagon is a polygon which has maximum coordinates

9 4. Location (2) Covering the entire FIR (permitted only for volcanic ash): ENTIRE FIR ENTIRE FIR (3) An area describing a zone defined by a line of a specified width (rather than a polygon): see the 'Vertical level and extent' section that follows. FIR

10 5. Vertical level and extent FLnnn SFC/FLnnn SFC/nnnnM SFC/nnnnFT FLnnn/nnn e.g. FL200/250 (lower level reported first) nnnn/nnnnft TOP FLnnn ABV FLnnn TOP ABV FLnnn nnn or nnnn is the relevant number SFC : TOP : ABV : surface cloud top above

11 5. Vertical level and extent Main Body (WV SIGMET) Horizontal extent An area describing a zone defined by a line of a specified width (rather than a polygon): FL<nnn/nnn> <nnn>km WID LINE BTN [<(lat,lon)p1 - (lat,lon)p2 - >] or FL<nnn/nnn> <nnn>nm WID LINE BTN [<(lat,lon)p1 - (lat,lon)p2 - >] e.g. FL310/ KM WID LINE BTN N4330 E N4315 E N4230 E N4145 E N4130 E02145 WID : BTN : width between

12 6. Movement or Expected movement MOV <direction> [speed <KMH or KT>] e.g. MOV NW 30KMH MOV E 25KT MOV SSW STNR Notes Movement information should not be provided when a forecast position is explicitly given. (REGIONAL SIGMET GUIDE) 7. Expected change in intensity INTSF WKN NC Given using one of 16 compass points MOV : KMH : KT : STNR : INTSF : WKN : NC : move km/h kt stationary intensify weaken no change

13 8. Forecast position of VA cloud at the end of the SIGMET validity period (1) An area of the FIR defined by a polygon: FCST <GGgg>Z VA CLD APRX <(lat,lon)p1 - (lat,lon)p2 - > e.g. FCST 1800Z VA CLD APRX N6300 E N6030 E N5815 E N6100 E N6300 E (2) An area describing a zone defined by a line of a specified width (rather than a polygon): FCST <GGgg>Z VA CLD APRX nnkm WID LINE BTN <(lat,lon)p1 - (lat,lon)p2 - > or FCST <GGgg>Z VA CLD APRX nnnm WID LINE BTN <(lat,lon)p1 - (lat,lon)p2 - > Notes :The GGggZ group should indicate the end of the validity period as given in the first line of the SIGMET message.
