Racing is set to go ahead at Randwick on the wettest track racecourse manager Nevesh Ramdhani has seen in his 4-1/2 years in the job.

But he is hopeful the forecast for clearing weather is correct and not too much rain falls before Saturday.

Racing NSW chief steward Ray Murrihy joined Ramdhani and other Australian Turf Club officials to inspect the track at midday on Friday and declared it safe for racing.

"When we went out this morning it was the wettest I've seen it," Ramdhani said.

"We had a clear few hours and it had improved out of sight by the time we walked it with Ray Murrihy.

"We have had a few showers since but as long as we don't get rain like we did overnight I'm confident we can race."

Stewards will inspect the track again at 6.30am on Saturday after horses have galloped on the track.

Around 90mm has fallen in seven days, 65mm in 24 hours.

Although there are likely to be a number of scratchings, the two favourites in the Winter Dash (1200m) are noted wet-track performers.

The Allan Denham-trained Mount Nebo was at $3.80 with the TAB on Friday ahead of last-start June Stakes winner Wouldnt it Be Nice at $4.80.

Trained by Paul Perry, Wouldnt It Be Nice has had five starts on heavy ground for two wins and a third.

His June Stakes win over leading Tattersall's Tiara contender Avoid Lightning came on a Soft 7.

"He loves wet tracks," Perry said.

"We have options for him like the Ramornie Handicap at Grafton next month but the tracks are quite often firm up there.

"He does perform well on good tracks but is much better when they are softer."

Mount Nebo has five wins and seven placings from 13 starts on soft or heavy tracks.

At his most recent start he finished fourth in the Listed Glasshouse Handicap on a good track at the Sunshine Coast won by Riva De Lago who finished fourth in last Saturday's Eye Liner Stakes at Ipswich.
