Storm damaged? Bother! (7)
I believe the answer is:
tornado
'storm' is the definition.
(tornado is a kind of storm)
'damaged? bother' is the wordplay.
'damaged?' becomes 'torn' ('torn' can be similar in meaning to 'damaged').
'bother' becomes 'ado' (I've seen this before).
'torn'+'ado'='TORNADO'
(Other definitions for tornado that I've seen before include "A violent and destructive whirlwind" , "A major blow" , "Terrible current" , "Violent rotating windstorm" , "Funnelling wind" .)
