Weather analysis and forecasting maps developed by the NOAA (USA) and the Met Office (UK) cover vast areas over the Wold. They can be obtained sending a request by email to the weather server of british company MailaSail. With the latter, many maps are available in a listing (¹) in which it suffices to click on the links to load the request in a message ready to send.

The page containing these links can be saved in RTF text format in the Apple "Files" carefully choosing "Location > On my iPad" and taking care to create a "Weather" folder in it beforehand, to be used on a regular basis for new requests from the tablet.
Two file formats are available for each weather graphic : Standard size (environ 40-60 KB) and reduced (SMALL : environ 20-30 KB). So we can get these maps by satellite phone choosing the SMALL size. A simple tap on one of the links opens the editor window in Apple Mail pre-filled.

Thank you very useful for my weather workshop with my club the RYCV
Thank you Francis, it's great
Thank you Francis, super!
Thank you Francis for this update of the 16 March .
It's GRIB well interpreted, humans are still needed while waiting for an Artificial Supra Intelligence.
These weather maps are more than a complement: They should be the basis for making a routing decision and should be treated with respect. A professional meteorologist worked there for several hours and took the time to do an in-depth analysis of the situation. He put all his knowledge into it, even signed it with his name under the heading FORCASTER. Just for NOAA, it is a small group of less than 100 people who sign all these cards. In contrast, a GRIB file is only the result of a calculation algorithm.
Really interesting, Thank you for sharing!
