Foreboding evil (7)

Ross

I believe the answer is:

ominous

(Other definitions for ominous that I've seen before include "Threatening, portending tragedy" , "Inauspicious" , "Threatening, doesn't look good" , "Portentous" , "Foreboding, threatening" .)

I've seen this clue in The Independent and The Mirror.
