Luna Rossa v Team UK
Leg 5 - Race committee has abandoned the race, which will now be resailed. Weather conditions have become too volatile to continue.
Incredible, after too little wind yesterday, we suddenly have a 30 knot squall threatening the safety of teams.
The key to that decision to abandon was the change of wind direction, which begs the question, will racing be moved to another course or this course reset, if it resumes today.

Kia ora, good afternoon and welcome to Newshub's live coverage of the America's Cup challenger series on Auckland's Waitematā Harbour and Hauraki Gulf.
After two days of racing, INEOS Team UK have jumped out to an impressive lead in the Prada Cup, making a remarkable turnaround from their impersonation of a paper plane in water during the pre-Christmas series.
The Brits are unbeaten from their three races, while Luna Rossa Prada Pirelli have just the one win from their two races and Dean Barker's NYYC American Magic are still looking for their first victory.
Saturday's racing saw Luna Rossa dominate in the light winds over American Magic, who really struggled, while surprising Team UK proved the three weeks of improvements to their boat have helped them significantly in lighter air.
Racing is due to begin at 3:15pm, with strong 15-20 knot northwest winds expected, playing into the hands of Sir Ben Ainslie, who loves the stronger breeze.
The action will take place on Course A, with the prime viewing for land-locked spectators from Milford and Takapuna.
TAB odds: Team UK $1.75 American Magic $3.75 Luna Rossa $3.75
Luna Rossa embracing light wind Cup racing: Bruni
Bring on the light winds - that's the storyline emerging from day two of the Prada Cup for Italian syndicate Luna Rossa.
A strange day of racing on the Waitematā Harbour saw victories for Luna Rossa and unbeaten INEOS Team UK - both bettering the struggling American Magic.
But constantly light winds, fluctuating from 7-11 knots, meant this wasn't a typical day of foil racing, with long periods of displacement racing - both up and downwind.
Co-helmsman on the Italian boat - Francisco Bruni - admits he wouldn't be disappointed if Sunday's two races brought similar conditions.
"In the light wind, definitely our big foils are helping us," says Bruni. "It's a combination of things, probably sails, power in the sails, power in the foils.
"We like the light wind definitely, but today was weird, because it was more gaining in the puffs. You had a difference of 3-4 knots. It was a matter of staying in the pressure."
Luna Rossa dominated winless American Magic in the opening race on Saturday, making the most of the tricky conditions and eventually building on the final leg, recording 40 knots in boat speed.
Conditions were so tricky, Patriot was left out on the course without a puff of wind in sight and eventually was handed a 'did not finish' by race officials.
"It was very challenging," Bruni says. "It was one of those races you can win or lose very easily.
"It was really demanding for the boys."
Unfortunately for the Americans, light winds are forecast for their sole race on Sunday against Luna Rossa.
Under the leadership of America's Cup veterans Terry Hutchinson and former Emirates Team NZ helmsman Dean Barker, the New York entry have had a disastrous start to a regatta they entered as favourites.
Three losses from three leaves the crew desperate for a win or face an uphill battle reach the Prada Cup finals next month.
Hutchinson says the crew are frustrated, especially with two big losses on Saturday, and hope Auckland's breeze will return, so they can show off their boat speed.
"Yesterday was a stable breeze day and we made some tactical mistakes.
"I think we're just looking for the opportunity to have a reasonably open race track and do what we know we can do, which is race well and put the boat in positions to let Patriot do her thing.
"I think we're all a bit angry. We know that's not who we are and I think we're all probably a bit pissed off.
"We want to go out and race consistently, and do things well and be who we are - that [performance] is not us.
"I'm sure if you said to everyone right now that we could go back out and race, we'd go back and race right now."
