When did boscastle flood?

Because of everything.

The torrential rain came for 24 hours causing The river Jordan to burst its banks. The flood made cars go under the water and people were airlifted out of their homes,

Yes, Boscastle was built on a flood plain. This is why, in 2004, Boscatle flooded as that area was where the water was naturally supposed to go

16th August 2004 it started at 12:00 and ended at 20:00
