Yes, if 'flying conditions' is prefaced by anything other than 'excellent' or 'good', do up your seat belt extra tight! I have trouble getting around thunderstorms because that word instills panic in some. 'The odd rain shower in the area' covers lightning that gives more light than darkness. 'Quite a lot of rain' covers the Bombay monsoon on June 15th. 'Quite breezy' does indeed cover Hurricane Kate. 'A little bumpy' covers turbulence that makes your fillings fall out.
I once came on the PA after landing at Gatwick in 'a little breezy and bumpy' weather that had everybody near panicking and broke the tension by saying 'we'd flown that route 50 times in the last year and it is always extremely boring. I'm sorry if you found it awful, but if it's any consolation, today we had a whale of a time and enjoyed in immensely, like a wonderful bracing sail in a yacht in a storm across the Bay of Biscay'. It worked.
