Violent storm split a party (7)

I believe the answer is:

tornado

'violent storm' is the definition.
(I know that tornado is a type of cyclone)

'split a party' is the wordplay.
'split' becomes 'torn' (I've seen this in another clue).
'party' becomes 'do' (do is a kind of party).
'torn'+'a'+'do'='TORNADO'

(Other definitions for tornado that I've seen before include "RAF fighter; whirlwind" , "Funnel-shaped windstorm" , "Violent whirling wind" , "Violent wind storm" , "squall" .)

I've seen this clue in The Telegraph.
