Atlantic and Pacific Offshore & High Seas Marine Forecasts by area

Atlantic Surface and Wind/Wave Analysis

The National Weather Service (NWS) Storm Prediction Center (SPC) routinely collects reports of severe weather and compiles them with public access from the database called SeverePlot (Hart and Janish 1999) with a Graphic Information System (GIS). The composite SVRGIS information is made available to the public primarily in .zip files of approximately 50MB size. The files located at the access point contain track information regarding known tornados during the period 1950 to 2006. Although available to all, the data provided may be of particular value to weather professionals and students of meteorological sciences. An instructional manual is provided on how to build and develop a basic severe weather report GIS database in ArcGis and is located at the technical documentation site contained in this metadata catalog.

Graphical depictions of the observed and forecast wind-driven waves for the Atlantic and Pacific Oceans adjacent to the coasts of the Continental United States (US) and extending south over the Caribbean Sea and the west coast of Central America. The gridded products are prepared for the initial wave heights and the 24 hour and 48 hour forecast wave heights in Gridded Binary (GRIB2) format.
