Storm, scattering gear (4)
I believe the answer is:
rage
'storm' is the definition.
(I know that storm can be written as rage)
'scattering gear' is the wordplay.
'scattering' indicates an anagram.
'gear' with letters rearranged gives 'RAGE'.
(Other definitions for rage that I've seen before include "Latest fashion; high emotion" , "Be furious" , "a poetic response to dying light?" , "Frenzy" , "Fit of anger" .)
