Proposed Changes to U.S. Weather and Navigation Broadcasts via NAVTEX
Reprinted with permission from NOTICE TO MARINERS No. 8, 25 February 2006The U.S. Coast Guard, in coordination with the National Weather Service, is proposing to modify the broadcasting of Maritime Safety Information (MSI) via NAVTEX, as detailed. This change is necessary in order to reduce the potential of delayed or missed broadcasts of MSI due to the large amount of information broadcast within the six daily broadcast slots for each NAVTEX station.

San Juan | R | 02001, 0600, 1000, 14001, 1800, 2200 |
New Orleans | G | 03001, 0700, 1100, 15001, 1900, 2300 |
1 Repeated Navigational Warnings and no Weather normally broadcast at these times. |
Currently, Meteorological Forecasts are broadcast four times per day and rebroadcast twice per day. Meteorological warnings are broadcast upon receipt and at the next routine scheduled time until canceled. Navigational Warnings are broadcast at the next available broadcast slot and rebroadcast in all subsequent slots as long as they remain in force.Under the proposed change, Meteorological Forecasts would no longer be rebroadcast. These two time slots would be allocated to rebroadcasts of Navigational Warnings. The proposed elimination of previously broadcast Meteorological Forecasts and reduction in repeated Navigational Warnings will reduce the potential of delayed or missed broadcasts of MSI.
