Hurricane or blizzard (5)
I believe the answer is:
storm
I believe this clue is a double definition.
'hurricane' is the first definition.
(thesaurus)
'blizzard' is the second definition.
(I've seen this in another clue)
(Other definitions for storm that I've seen before include "= Gale force 10" , "violent reaction" , "Rampage" , "Uproar" , "Sandy, perhaps" .)
