Can't really add anything to the excellent replies of Standard Noise or ATCOJ30 but surely any information is better than no information?
If I was departing Bristol for some far flung destination then I think I would be grateful to have heard of a met warning on the ATIS advising me of some or other unclement weather that I might expect on my return. At least then I can prepare for all eventualities. Quite surprised that some pilots have not heard of met warnings anyway, surely there might be some holes in training/education that need to be addressed?
