What data base does MS draw weather from...

...and is it possible to gather ocean and sea data and create them in FS for the sea planes? Wouldn't have to be a big detailed simulation just a way to have it where not all bodies of waters are accessable for take-off or landings. If sea conditions arent downloadable maybe use the weather data to create seas by wind direction and strength and then create seas that kind of would relate to those reports. It sure would bring a whole new experience into aviation on water.Kilstorm
