He advises people at the storm centre (6)
I believe the answer is:
mentor
'he advises' is the definition.
(I've seen this before)
'people at the storm centre' is the wordplay.
'people' becomes 'men' (men can refer to humanity as a whole).
'at' is a charade indicator (letters next to each other).
'centre' means to look at the middle letters.
The middle of 'storm' is 'tor'.
'men'+'tor'='MENTOR'
(Other definitions for mentor that I've seen before include "No term for instructor" , "Experienced adviser" , "Counsellor/guide" , "Guru" , "One who steers" .)
