Compass showing north during storm (5)
I believe the answer is:
range
'compass' is the definition.
(I've seen this before)
'north during storm' is the wordplay.
'north' becomes 'n' ('N' can be a synonym of 'north').
'during' indicates putting letters inside.
'storm' becomes 'rage' ('rage' can be a synonym of 'storm').
'n' inserted inside 'rage' is 'RANGE'.
'showing' is the link.
(Other definitions for range that I've seen before include "Number of items in a series" , "Array" , "Variety; wander" , "Enclosed kitchen fireplace" , "Scope (for target practice?)" .)
