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 simply click on the links to load the request in a message ready to send.
Saving the MailaSail Answering Machine List
The page containing these links can be saved in RTF format in the Apple app "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 (about 40-60 KB) and reduced (SMALL : about 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 prefilled.
Reception in Apple Mail
Once received in Apple Mail, the graphic is displayed as an attachment after the text. A tap on the image allows to share with Apple app "Books".

These graphic weather charts are an essential complement to the GRIB files when sailing in the open sea. They are easily downloaded by satellite phone thanks to small sizes.

Thank you very useful for my weather workshop with my club the RYCV
Thank you Francis, it's great
Thank you Francis, super!
Francis thank you for this update 16 March .
It is well understood GRIB, the human is still necessary until a Supra Artificial Intelligence.
These weather maps are more than an add-in: They should be the basis of work to make a routing decision and should be treated with respect. A professional meteorologist worked there for several hours and took the time to do an analysis of the situation in depth. Ago put all his knowledge even signed it with his name under the heading FORCASTER. Just for NOAA, It's a small group under 100 people who sign these cards. As opposed, a GRIB file is only the result of a calculation algorithm.
Really interesting, Thanks for sharing this!
