f-bomb

I'm a little stuck... Click here to teach me more about this clue!

'facebook suppressed weather' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'bureau swearword' is the wordplay.
I cannot quite see how this works, but
'bureau' could be 'omb' (OMB is an example) and 'omb' is found in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
