They have just up graded the forecast to 18 to 23 knots. I reckon it might happen in the arvo, if the change get a push by the saebreeze it might get strong later.
Chris, I would keep and eye on Kent Reserve, it is already 16 knots down there. Can you get Tuesday off......at the moment it looks like there could be wind.
Anyway good luck I will be looking to sail in the arvo.
