Out of the blue

What does "Out of the blue" mean?

Today it means: Unexpected, suddenly.

This saying comes from a sudden and un-expected squall on an otherwise perfect day with clear blue sky. In such conditions a ship is likely to have full sail and would not be able to shorten them quickly. If gusts of wind catch a ship in full sail it can be devastating. Such things happen regularly if sailing leeward to a range of hills. Even a gentle breeze on a perfect day can turn violent as it spins off the top of a hill and could hit a vessel from any direction.
