Mariners Weather Log

The Mariners Weather Log (MWL), a publication of the National Weather Service (NWS), contains articles, news and information about marine weather events and phenomena, worldwide environmental impact concerns, climatology studies, storms at sea, and weather forecasting. The MWL is dedicated to the NWS Voluntary Observing Ship (VOS) Program, Port Meteorological Officers (PMOs), cooperating ships officers, and their vessels.

The MWL provides meteorological information to the maritime community, and contains a comprehensive chronicle on marine weather. Through the MWL, the VOS program recognizes ships officers for their efforts as voluntary weather observers, and allows the NWS to maintain contact and communicate with over 10,000 shipboard observers worldwide (ships' officers) in the merchant marine, NOAA Corps, Coast Guard, Navy, etc.

The MWL is currently published three (3) times per year (April, August, & December), and is distributed via email to mariners, marine institutions, the shipping industry, scientists, educational and research facilities, libraries, government agencies, and offices worldwide in a digital high resolution format. It is permissible to print the MWL from this format.
