Dud limes, sadly, might be the result of too much rain (8)
I believe the answer is:
mudslide
'be the result of too much rain' is the definition.
I can't judge whether this definition defines the answer.
'dud limes sadly' is the wordplay.
'sadly' indicates anagramming the letters.
'dud'+'limes'='dudlimes'
'dudlimes' is an anagram of 'MUDSLIDE'.
'might' is the link.
Can you help me to learn more?
(Other definitions for mudslide that I've seen before include "Slippage of wet earth" , "Hillside slippage" , "Dim duels (anag) - natural hazard after heavy rains" .)
