'bad weather' is the definition.
'tornado' can be an answer for 'weather' (I have seen 'Destructive weather' mean 'tornado' so perhaps 'weather' could also mean 'tornado'). I'm not certain of the 'bad' bit.

'to the navy much fuss' is the wordplay.
'the navy' becomes 'RN' (abbreviation for Royal Navy).
'much fuss' becomes 'ado' (synonyms. I am not sure about the 'much' bit.).
'to'+'rn'+'ado'='TORNADO'

'means' is the link.
