humour me but coming into LHR the other day (and not adviSed of a late change of rwy) we were advised of moderate snow falling....jeez... That to me is buckets of snow falling, braking action comes to mind etc etc.....in reality it was a sprinkle of wet snow....what is defined as moderate snow, as giving reports of same rachets up a situation where uncalled for. I was'nt with impressed with them at all.........
