Hardest areas after storm revealing place with water shortage (6,6)
I believe the answer is:
sahara desert
'place with water shortage' is the definition.
(desert with very little water)
'hardest areas after storm' is the wordplay.
'after' is a charade indicator (letters next to each other).
'storm' is an anagram indicator.
'hardest'+'areas'='hardestareas'
'hardestareas' anagrammed gives 'SAHARA DESERT'.
'revealing' is the link.
(Other definitions for sahara desert that I've seen before include "World's largest sandy area" , "Uncultivated region of north Africa" , "Dry region of Africa" .)
