There are many reports of odd things dropping from the sky. Fish, various crustaceans and frogs seem to be most common and these are usually put down to tornadoes/waterspouts lifting them from their habitats and dropping them somewhere else.
That's certainly plausible. The UK does get a fair amount of tornado activity, not usually with the strength of those seen elsewhere in the world but once in a while a big one does come along.
Apples though, are an oddity. Especially in December, when they should all have been harvested in September and October.
There are more strong winds forecast. Perhaps there'll be another bizarre celestial delivery somewhere.
