Fwiw, I too concur with what PPRuNe Towers has said (
above) about Cb activity just offshore at BEY (
Orographic uplift?) and of the very able ground based Wx radar system they use.
My most recent flight to Beirut was 21st Jan during which we too had Cb's (
plus a quite low freezing level on departure, with ice soon to form under the wiper blade and also on the wiper nut).
ATC were top notch on our arrival (
giving us excellent vectors to avoid, i.e. before we had to ask for it) and likewise, pre-takeoff, giving us a clearance that would see us clear the Cb's on the departure track - top stuff!
As for the Cb's themselves, whilst they might not be the size of summer ones, they are not to be under estimated!
