Thunder-and-lightning event (5)
I believe the answer is:
storm
'thunder-and-lightning event' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for storm that I've seen before include "Trouble" , "Rampage" , "Wind force 10 on Beaufort scale" , "X-Men character" , "Shout angrily, assault" .)
