See storm erupts in county (8)
I believe the answer is:
somerset
'county' is the definition.
(I know that Somerset is a county)
'see storm erupts' is the wordplay.
'erupts' indicates anagramming the letters.
'see'+'storm'='seestorm'
'seestorm' is an anagram of 'SOMERSET'.
'in' acts as a link.
(Other definitions for somerset that I've seen before include "head over heels" , "English county known for its cider and Cheddar cheese" , "Cheddar Gorge's county" , "Wells's county" , "County; acrobat move" .)
