Tropical Surveillance is provided automatically to all of our SeaWeather "Basic" and "Premium" subscribers. As a subscriber, you will receive a once daily WRI Tropical Summary, outlining all tropical features for your current ocean basin, along with any other regions that you specifically request. The summaries can be viewed both in your e-mail and online at your SeaWeather home page at login.

The summaries describe the movement and likelihood of development of any tropical features, along with descriptions and forecast positions for any active tropical systems, whether the system is classified by national/local government agencies or not. WRI's team of Meteorologists are always closely monitoring tropics worldwide.

Our forecast charts are generated from a variety of model data, including high resolution weather forecast models that are run "in house". The charts are updated 4x daily, and are available at several different "zoom" levels, from entire ocean basins to high resolution coastal areas. Forecast data is available out to 180 hours for long range planning.

Please note that we do not recommend using model forecast data as a "do it yourself" method of forecast/routing at sea. We encourage our clients to use SeaWeather as a supplement to our traditional forecast and routing services, as a means to graphically interpret the reasoning behind the detailed recommendations of our forecasters.
