Hot wind from Morocco is back for the moment (7)
I believe the answer is:
sirocco
'hot wind' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
(Other definitions for sirocco that I've seen before include "Hot wind blowing from north Africa to southern Europe" , "Hot south wind from North Africa" , "Wind from the desert" , "Hot wind that blows across the Mediterranean" , "Dust storm" .)
