Sudden blast of wind (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
gust
'sudden blast of wind' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for gust that I've seen before include "Flurry" , "Burst of strong wind" , "Sudden blow of wind" , "Blast of air" , "Sudden rush of wind" .)
