5. TROPICAL CYCLONE ADVISORY CENTRES (TCAC) 5.1 Tropical cyclone advisory information 5.1.1 The advisory information on tropical cyclones shall be issued for tropical cyclones when the maximum of the 10-minute mean surface wind speed is expected to reach or exceed 63 km/h (34 kt) during the period covered by the advisory. 5.1.2 The advisory information on tropical cyclones shall be in accordance with the template shown in Table A2-2. 5.1.3 Recommendation.— When the tropical cyclone advisory information is issued in binary format, the BUFR code form should be used. Note.— The BUFR code form is contained in WMO Publication No. 306, Manual on Codes, Volume I.2, Part B — Binary Codes. Annex 3 — Meteorological Service for International Air Navigation Appendix 2 7/11/07 APP 2-6 Table A2-1. Template for advisory message for volcanic ash Key: M = inclusion mandatory, part of every message; O = inclusion optional; = = a double line indicates that the text following it should be placed on the subsequent line. Note 1.— The ranges and resolutions for the numerical elements included in advisory messages for volcanic ash are shown in Appendix 6, Table A6-4. Note 2.— The explanations for the abbreviations can be found in the Procedures for Air Navigation Services — ICAO Abbreviations and Codes (PANS-ABC, Doc 8400). Note 3.— Inclusion of a “colon” after each element heading is mandatory. Note 4.— The numbers 1 to 18 are included only for clarity and they are not part of the advisory message, as shown in the example.
