Clip of Willie Wonka heading for Washington twisted with violent wind! (8)

'wind' is the definition.
(I know that Williwaw is a type of wind)

'clip of willie wonka heading for washington' is the wordplay.
'clip of' means to remove the last letter (clip can mean a shortening of something).
'heading' says to take the initial letters (head could mean the top letter).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'washington' becomes 'wa' (abbreviation for the US state).
The initial letter of 'wonka' is 'w'.
'willie' with its last letter taken off is 'willi'.
'w' put after 'wa' is 'waw'.
'willi'+'waw'='WILLIWAW'

'twisted with violent' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?
