Destructive weather feature developing rapidly (9)
I believe the answer is:
whirlwind
'feature developing rapidly' is the definition.
I can't tell whether this defines the answer.
'destructive weather' is the wordplay.
'destructive' becomes 'whirl' (I can't explain this - if you can you should give a lot more credence to this answer).
'weather' becomes 'wind' (wind is a kind of weather).
'whirl'+'wind'='WHIRLWIND'
Can you help me to learn more?
(Other definitions for whirlwind that I've seen before include "Cyclone" , "Impulsive" , "(Of a romance) rapidly sweeping you off your feet?" , "Energetic person" , "Atmospheric eddy" .)
