U S Navy Flag's assault on the $13million The Everest could be derailed if the rain continues to pour down in Sydney, the Coolmore team fear.
Trained by Aiden O'Brien, U S Navy Flag is the first internationally-trained runner to contest the race, which is in just its second year, and it is fair to say connections were hoping for a dry track.

That looked to be on the cards following one of the driest winters on record, but Sydney has copped 70mm of rain in the last week and the track is currently rated a heavy (8).
More rain is forecast tomorrow, Friday and Saturday and that is not good news for O'Brien and his team.
"He appeared to handle the ground a lot better today than he did last time he galloped on it," Coolmore Australia principal Tom Magnier said.
"We're very happy with how he worked this morning. The rain could be a problem for us. If there's more rain I'm going to be worried about.
"If it's like the ground he worked on this morning I'll be happy with it."
Coolmore's travelling head Andrew Murphy was also satisfied with his main workout ahead of Saturday but he also revealed concerns over a heavy track.
"I was very happy with his work this morning but obviously the ground condition is not ideal," he said. "Everything has gone very smoothly so far, we're very happy with him, we just hope the ground can dry up by Saturday.
"No doubt the ground is a concern. War Front's need, the faster it is the better.
"He's won on good to soft but it was probably more good than soft that day in the Middle Park. If it stays dry we should be ok, any more rain won't be favourable."
US Navy Flag is 10/1 on a win and each way bet to win The Everest with Trapeze Artist 9/1 and Vega Magic 6/1.
On the same day The Autumn Sun is 7/10 to win the Caulfield Guineas.
