Light winds means there could be no America's Cup racing today in Auckland.
Team New Zealand and Luna Rossa are locked at one all in the race to seven for the Auld Mug after the first two races on Wednesday.
However regatta director Iain Murray said light winds at the bottom of the acceptable wind range are forecast ahead of the first race, which is scheduled for quarter part four this afternoon.
"The lower limit is an average of 6.5 knots measured for five minutes shortly before the start of the race," he said.
"The forecast shows a variety of conditions with 2-7knots of breeze from the northeast.".
"Should we get a race away, when it comes to time limits a boat needs to complete the first leg in 12 minutes, after that the deadline for the completed race is 45 minutes."
Racing must also start before 6pm.

Such light conditions will mean that foiling could be tricky and make staying on the foils a crucial part of the game.
This in turn influences tactics and strategy, particularly in the pre-start where teams may seek to force each other off their foils, but without splashing down themselves.
At times we have seen teams consider this tactic as presenting too high a risk and have chosen to avoid engaging with their opponents instead.
Until now, light conditions have been considered to favour the Italians, but Team New Zealand has been trying a new code zero sail, to help in lighter air.
