Presage, foreshadow (7)
I believe the answer is:
portend
I believe this is a double definition.
'presage' is the first definition.
(I know that presage can be written as portend)
'foreshadow' is the second definition.
(I know that foreshadow can be written as portend)
(Other definitions for portend that I've seen before include "Threaten" , "Give warning" , "Be a sign of (impending calamity)" , "Be a sign of something to come" , "Betoken; presage" .)
