Waterlogged Warwick inspect
Warwick's fixture on Bank Holiday Monday is subject to an 8.30am inspection on Saturday.
The course is waterlogged in places following 103 millimetres of rainfall throughout April.
The situation was also compounded by further 16mm of rain on Thursday.
Clerk of the course Sulekha Varma said: "The situation has gradually deteriorated as the week has gone on.
"Thursday's rain has left us in an unraceable state, with large areas of false ground and some waterlogging.
"If there is some improvement on Saturday morning, we might look again on Sunday, but it's not looking great."
