Drizzles or pours (5)
I believe the answer is:
rains

'drizzles' is the first definition.

'pours' is the second definition.
(I've seen this in another clue)
(Other definitions for rains that I've seen before include "Tropical wet season" , "Falls in droplets" , "Showers" , "Comes down from cloud" .)
