Warwick’s meeting on Friday is subject to an 8am inspection tomorrow.
The course is still slightly frozen in places but temperatures are due to stay above freezing overnight.
Clerk of the course Andrew Morris said: “We are still really positive. We are very close to being raceable today.
“I’m just not quite confident enough to say we are completely fit for racing when we are asking people to declare tomorrow.
“So, we’ll have a look in the morning and we’ll keep everybody informed. The temperatures overnight are good, 3C is the lowest we should reach.”
