He will shortly create uproar (4)
I believe the answer is:
hell
I believe this clue is a double definition.
'he will shortly' is the first definition.
(common abbreviation)
'uproar' is the second definition.
(I've seen this before)
'create' is the link.
(Other definitions for hell that I've seen before include "Unpleasant place" , "Tartarus, of myth" , "Place of vice, misery or turmoil" , "Abode of the forces of evil" , "Abode of the damned" .)
