Tropical Tidbits :

This website’s primary purpose is to be a home for Atlantic tropical forecast discussions offered by myself (Levi Cowan) and various projects I am developing related to tropical meteorology. My forecasts do not represent the prognostications of any government office. Please visit the National Hurricane Center for official information, some of which can be found on the current storm information page.

I have been tracking tropical cyclones closely since 2002, and am currently a graduate meteorology student at Florida State University.

SailDocs GRIB Service : Like most GRIB services, Saildocs. extracts files on a per request basis from the US NOAA/NCEP global GFS computer model. File size depends upon the amount of data requested and can be from a few tens of kb upwards.

Output is available up to 15 days ahead although I would only recommend using up to 8 days. Beyond that is of academic interest only. The US NWS runs its computer model 4 times a day using data at 00, 06, 12 and 18 hours UTC.

Lee Chesneau’s Marine Weather : Lee Chesneau’s Marine Weather plans to accomplish its vision by first instilling trust in the work done by this country’s most qualified, talented and dedicated professional marine meteorologists. The structure of the National Weather Service and its marine program is a service to every mariner thanks to government funding that is already in place. There are no additional costs for this invaluable resource!

TidesChart : Check the tide anywhere in the world.

PassageWeather.com : PassageWeather.com specializes in Sailing Weather Forecasts, and was developed out of the need for reliable, easy to use weather information… We provide 7-day Wind, Wave and Weather Forecasts to help sailors with their passage planning and weather routing.

TheWeatherPrediction.com : The main focus of this web site is weather prediction education. While there are many websites for retrieving weather data, there remains somewhat of a lack of weather data interpretation and forecasting methods. This site will benefit the beginner as well as the advanced forecaster.
