Big news: Weather agency with outside bets on eternal fire (9)
I believe the answer is:
bombshell
'bets on eternal fire' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'big news weather agency with outside' is the wordplay.
I cannot quite understand how this works, but
'agency' could be 'omb' (OMB is an example) and 'omb' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bombshell that I've seen before include "big disappointment" , "Big surprise" , "Piece of devastating news" , "Sudden and surprising piece of news" , "Explosion" .)
