VRC Track Manager Liam O'Keeffe has warned that punters should not expect Flemington's racing surface to drain at the same rate this Saturday as it did on Melbourne Cup Day.
Flemington was widely praised for its performance on November 6, when the course was hit with a significant deluge and still managed to improve from a Heavy 8 to a Soft 6 within the space of hours.
But with the course proper fresh from a post-carnival renovation, O'Keeffe has suggested it is likely to hold more moisture this weekend.
"If we got this amount of rain two days before Derby Day it wouldn't have as much effect," he said.
"But the grass is quite new and still in recovery from the renovation so I don't expect it will drain as quickly as what it did on Cup Day.
"It is quite fluffy, the surface isn't as thick as what it was heading in to the carnival."
Melbourne, like most of Victoria, has been hit with significant rainfall on Thursday and more is forecast for Friday, along with scattered showers on Saturday.
"If we took a crystal-ball approach and say we get 30mm or so on Thursday and then another 10-15mm on Friday, then I would say we would be racing on a Soft 6 close to a Soft 7 but we will just have to wait and see how much rain does fall and then what occurs on Saturday," O'Keeffe said.
