Copies found in cyclone shelter (6)
I believe the answer is:
clones
'copies' is the definition.
(cloning is a kind of copying)
'in cyclone shelter' is the wordplay.
'in' indicates a hidden word.
'CLONES' is hidden in the letters of 'cyclone shelter'.
'found' is the link.
(Other definitions for clones that I've seen before include "Identical copies produced by genetic engineering" , "Identical copies of cells" , "Genetically identical copies" , "Organisms reproduced asexually" , "Genetically identical organisms derived from a single cell" .)
