Weather aboard Milo

Weather sites (the first two are in French)

• Worldwide tropical cyclone tracking: Cyclone Xtreme
• Bulletins, charts and GRIB files, worldwide: Meteo Marine
• Weather forecasts for sailors and adventurers: PassageWeather

iPad weather apps (the pick of the bunch):

• Weather4D sets out to give you worldwide weather. Through a simple, intuitive interface you watch your weather data in four dimensions: Weather 4D
• Hurricane HD — the ultimate hurricane tracking experience.
• Earthquake Hound — by far the best app for watching all that activity on a full-screen map, and for following tsunami warnings.
