Fuss about fleet meeting a storm (7)
I believe the answer is:
tornado
'storm' is the definition.
(type of weather)
'fuss about fleet meeting a' is the wordplay.
'fuss' becomes 'todo' (both can mean a commotion).
'about' indicates putting letters inside.
'fleet meeting' becomes 'rn' (I can't explain this - if you can you should give a lot more credence to this answer).
'rn'+'a'='rna'
'todo' placed around 'rna' is 'TORNADO'.
Can you help me to learn more?
(Other definitions for tornado that I've seen before include "Road not turned in the windstorm" , "Whirling storm" , "Terrible current" , "It's a big blow" , "Tempest'" .)
