I'll Answer you with the maximum knowledge I know untill I make sure of any one of the working ATCs
To get the MET info that would be only through the ATIS on each airport only HECA,Cairo Intl Currently have an ATIS all other airports don't have an ATIS but controllers Have to provide the latest weather observation for departing traffic before giving them the ATC Clearance
Email usage is increasing in Egypt for governmental conversations and related some are available on the AIP (PM Me if you need something from) But telex is also still there in use
Hope I helped by what I know though I don't think i did much
Regards and will be back with a more preicse answer from a real ATC
