Storm to trouble British sailors being sucked in (7)
I believe the answer is:
tornado
'storm' is the definition.
(type of weather)
'to trouble british sailors being sucked in' is the wordplay.
'trouble' becomes 'ado' (both can mean bother or commotion).
'british sailors' becomes 'RN' (Royal Navy).
'being sucked in' is an insertion indicator (some letters are sucked inside).
'to'+'ado'='toado'
'toado' enclosing 'rn' is 'TORNADO'.
(Other definitions for tornado that I've seen before include "Rapidly whirling column of air" , "Whirling windstorm" , "Cyclone, twister" , "great deal of wind" , "Funnelling wind" .)
