The Sydney to Hobart yacht race fleet have been warned they could face strong winds shortly after the start on Boxing Day.
A long-range weather briefing yesterday indicated the 117 yachts will begin racing in light easterly winds on Sydney Harbour but they should be prepared for conditions to get livelier quickly.
"As the boats move out of the heads and start making their way down south, they'll encounter wind speeds of around 20 to 30 knots," said New South Wales Bureau of Meteorology's Andrew Treloar.
"And it is likely we will have a strong wind warning."
Later in the race, a period of slack winds is expected to favour the small-to-medium sized boats. The super-maxis at the front of the fleet will be most affected by light air expected to arrive as the lead boats reach Bass Strait between the mainland and Tasmania.
