Pass over region in a storm (6)
I believe the answer is:
ignore
'pass over' is the definition.
(thesaurus)
'region in a storm' is the wordplay.
'in a storm' is an anagram indicator.
'region' is an anagram of 'IGNORE'.
(Other definitions for ignore that I've seen before include "Blank" , "Walk away from" , "Pay no attention to, disregard" , "Deliberately disregard" , "Dismiss" .)
