Bizarre, her dorm stunts, they’re noisy with lots of water! (13)

I believe the answer is:

thunderstorms

'they're noisy with lots of water' is the definition.
(thunderstorms are noisy rainstorms)

'bizarre her dorm stunts' is the wordplay.
'bizarre' indicates an anagram.
'her'+'dorm'+'stunts'='herdormstunts'
'herdormstunts' anagrammed gives 'THUNDERSTORMS'.

(Another definition for thunderstorms that I've seen is " weather".)

I've seen this clue in The Times.
