The primary weather information for mariners is provided by which organization?

• A. National Weather Service broadcast
• B. Coast Guard Weather Center
• C. Local Port Authority
• D. Private meteorological firm

Answer: (A)

Mariners rely on authoritative, official forecasts and warnings provided by the National Weather Service. The NWS is the federal agency charged with issuing marine forecasts, warnings, and advisories that cover coastal waters, the open sea, and inland waterways. These marine products are distributed through NOAA Weather Radio and other NWS broadcast channels, making them the primary source mariners depend on for planning and real-time navigation decisions. The Coast Guard Weather Center supports safety operations and coordination but is not the main source of the official forecasts mariners use. Local port authorities and private meteorological firms can provide helpful information, but they do not supersede the official NWS marine forecasts.
