Warwick have announced an 8am inspection for tomorrow.
The track is currently heavy, waterlogged in places after having been hit by 13 millimetres of overnight rain.
Clerk of the course Andrew Morris said: “There are areas that are waterlogged, particularly down the back straight.
“The forecast is for a largely dry day, with the possibility of a few showers, and the same into tomorrow.
“I’m a little bit downbeat because we do need to improve.”
