I believe the answer is:

tempest

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

'a storm?' is the definition.
(I know that storm can be written as tempest)

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for tempest that I've seen before include "Cyclone" , "Shakespearean storm?" , "Met pets in fierce storm" , "Violent Shakespearian storm" , "Violent storm (created by Shakespeare?)" .)

I've seen this clue in The Times.
