Road not damaged in storm (7)
I believe the answer is:
tornado
'storm' is the definition.
(tornado is a kind of storm)
'road not damaged' is the wordplay.
'damaged' is an anagram indicator.
'road'+'not'='roadnot'
'roadnot' with letters rearranged gives 'TORNADO'.
'in' acts as a link.
(Other definitions for tornado that I've seen before include "Severe wind" , "Violent wind vortex" , "Funnelling wind" , "Violent whirlwind over land" , "Funnel-shaped windstorm" .)
