Outbreak of public excitement (6)
I believe the answer is:
furore
'outbreak of public excitement' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for furore that I've seen before include "To-do" , "An uproar, of admiration or anger" , "An uproar, outbreak of fury" , "Public indignation" , "Sudden outburst, uproar" .)
