Exeter on weather watch
Exeter's meeting on Sunday is subject to an 8am inspection on Saturday morning.
Although the track was found to have been raceable on Thursday morning, more rain has been forecast.
The going is currently heavy.
Exeter general manager Tim Darby said: "We had eight millimetres of rain overnight on top of nearly 80mm in the last three days, but we are raceable at the moment.
"There is more rain forecast so we'll have an inspection on Saturday and see where we are.
"The course here dries very quickly and we have a strong wind at the moment, which will help."
