@YacineBoussoufa @filip_k Hi, I am the owner of the website.
The coverage is for almost all of saudi arabia except the eastern part of it and there are some blind spots there and there. and the north eastern part should be covered by Kuwait radar but the radar is currently closed to do conflicts (which sounds weird but well yeah)
Also the radar timing system works different I think
so the radar starts capturing lets say 4:15 until 4:20 and releases an update. you could say 4:15 is actually 4:20 update. although sometimes there are some delays and corrupt images due to problems that happen from the national center there and it really sucks but yeah.

Also for UAE/Sultanate of Oman/Bahrain/Qatar theres radar and I can give the API for free on my email if you want with a key so it doesn't get releases/abused and I might consider mixing my radar with all of them later.
