Wet weather has forced officials to postpone the scheduled race meeting at Warwick Farm on Wednesday.

While the track was initially given the all-clear following an early-morning inspection, persistent rain tipped it into the unsafe range and the decision was made to move the meeting to Friday.

The postponement of the Warwick Farm card follows the abandonment of Tuesday's barrier trial session after just five heats due to the state of the track.

Rosehill has been rated a heavy nine ahead of Saturday's Group Two Expressway Stakes program.
