Storm in Rush? (6)
I believe the answer is:
assail
This clue is a double definition.
'storm' is the first definition.
(I've seen this before)
'rush?' is the second definition.
(rushing is a kind of assailing)
'in' is the link.
(Other definitions for assail that I've seen before include "Attack violently and persistently" , "Aggressively attack" , "Beset" , "Molest or harass" , "Make violent attack on" .)
