Rent fuss causes violent storm (7)
I believe the answer is:
tornado
'violent storm' is the definition.
(tornado is a kind of violent storm)
'rent fuss' is the wordplay.
'rent' becomes 'torn' (synonyms).
'fuss' becomes 'ado' (synonyms).
'torn'+'ado'='TORNADO'
'causes' acts as a link.
(Other definitions for tornado that I've seen before include "Whirling storm" , "Donator of fierce wind" , "Funnelling wind" , "A violent and destructive whirlwind" , "Funnel-shaped windstorm" .)
