Principles

  8.1.2 The principles for the preparation and issue of warnings and weather and sea bulletins are as follows:

  • .1 For the purpose of the preparation and issue of meteorological warnings and the regular preparation and issue of weather and sea bulletins, the oceans and seas are divided into areas for which national Meteorological Services assume responsibility.

  • .2 The areas of responsibility together provide complete coverage of oceans and seas by meteorological information contained in warnings and weather and sea bulletins.

  • .3 The issue of meteorological warnings and routine weather and sea bulletins for areas not covered by NAVTEX shall be broadcast by the International SafetyNET Service for the reception of maritime safety information (MSI) in compliance with SOLAS chapter IV “Radiocommunications”, as amended.

  • Note: In addition, national Meteorological Services may have to prepare and/or issue warnings and routine forecasts for transmission by an HF-direct printing telegraphy maritime safety information service for areas where such a service is provided for ships engaged exclusively on voyages in such areas.

  • .4 The preparation and issue of warnings and weather and sea bulletins for areas of responsibility are coordinated in accordance with the procedures mentioned in the Manual on Marine Meteorological Services (WMO No. 558) and the Guide to Marine Meteorological Services (WMO No. 471), and summarized in the following section.

  • .5 The efficiency and effectiveness of the provision of warnings and of weather and sea bulletins are monitored by obtaining opinions and reports from marine users.

  • .6 Maritime Safety Information broadcasts are monitored by the originating Issuing Service to ensure the accuracy and integrity of the broadcast.
