Team's curtailed debuts in local league in gusty weather (6)
I believe the answer is:
squall
'gusty weather' is the definition.
'squall' can be an answer for 'weather' (squall is a kind of weather). I'm not sure about the 'gusty' bit.
'team's curtailed debuts in local league' is the wordplay.
'team' becomes 'squad' (sports team).
'curtailed' means to remove the last letter.
'debuts in local league' becomes 'll' (I can't justify this - if you can you should believe this answer much more).
'squad' with its final letter taken off is 'squa'.
'squa'+'ll'='SQUALL'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for squall that I've seen before include "Short-lived violent gust of wind and rain" , "Sudden brief storm" , "Sudden strong wind" , "Sudden violent gust of wind" , "Sudden violent storm" .)
