Marine weather forecasting is the process by which mariners and meteorological organizations attempt to forecast future weather conditions over the Earth's oceans. Mariners have had rules of thumb regarding the navigation around tropical cyclones for many years, dividing a storm into halves and sailing through the normally weaker and more ...
Embedded in these high seas areas are smaller offshore zones off the Atlantic and Pacific coasts. These zones extend from near the coast seaward to just beyond the U.S. Exclusive Economic Zones, out to about 250 nautical miles (460 km). OPC services ensure the safety of the extensive commercial and recreational fishing, boating, and shipping ...

A NAVTEX receiver prints an incoming message NAVTEX message for the Baltic Sea. NAVTEX (NAVigational TEleX), sometimes styled Navtex or NavTex, is an international automated medium frequency direct-printing service for delivery of navigational and meteorological warnings and forecasts, as well as urgent maritime safety information (MSI) to ships.
Weather Buoy / Data Buoy / Oceanographic Buoy operated by the Marine Data Service. The first known proposal for surface weather observations at sea occurred in connection with aviation in August 1927, when Grover Loening stated that "weather stations along the ocean coupled with the development of the seaplane to have an equally long range, would result in regular ocean flights within ten years."
A weather window occurs when weather forecasts indicate that a given set of marine operations or offshore construction activities can be performed within their maximum limits for wave height, wind speeds etc. Critical elements for offshore operations are use of time and expected weather.
The National Weather Service issues a similar high wind warning (Specific Area Message Encoding code: HWW) for high winds on land. The criteria vary from place to place; however, in most cases, the warning applies to winds of 40 miles per hour (64 km/h) to 73 miles per hour (117 km/h) for at least 1 hour; or any gusts of 58 miles per hour (93 km/h) to 114 miles per hour (183 km/h) on land.
An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. [1] Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and ...
