TCM-8/Doc. 4.3.1, APPENDIX
The Decision of the 17th WMO Congress
The WMO publication WMO-No. 1157 – Abridged final report with resolutions of the Seventeenth
World Meteorological Congress contains the following paragraph that is requested to follow:
3.1.65 Congress noted that the regionally coordinated systems under TCP had covered all ocean
basins prone to tropical cyclones. However, Congress noted that some Members on the periphery
of ocean basins such as the Arabian Sea are occasionally struck and/ or influenced by tropical
cyclones, although there is no reference to the handling of such tropical cyclones in the existing
warning system procedures. Considering the essential roles of the regionally coordinated system
in supporting Members of the five regional tropical cyclone bodies to provide reliable and timely
forecasts of tropical cyclone tracks and intensities, and related forecasts of strong winds, heavy
rainfall, and storm surges, etc., Congress requested the Secretary-General to establish a reliable
link, and develop a mechanism with the support of the regional associations, to include all
Members affected by this hazard into the regionally coordinated system.
