Why not? I'm making an entirely different point altogether: Warnings are just that: they are not promises of gargantuan, tropical deluges everywhere within the area mentioned. And, how do I know this? I lived in the NW Highlands on many days when snow was forecast, for NW Scotland...And, more often than not, it all fell 'elsewhere'!
Warnings are about probabilities not certainties. It can be bloody annoying sometimes, though!
