Fairyhouse officials will hold an early morning inspection to decide if Wednesday's meeting can go ahead as planned.
Following heavy rain, an inspection today found that a small section of the course is currently unfit for racing due to standing water.
With a mainly dry forecast between this afternoon and race time tomorrow, a 7.30am inspection will be necessary and with temperatures set to drop overnight, it's not a forgone conclusion.
Brendan Sheridan, IHRB Clerk of the Course at Fairyhouse said: "Following 3mm of rain overnight and a further 6mm of rain throughout today, there is one small part of the track which is unfit for racing due to surface water.
"It has stopped raining here at Fairyhouse since lunchtime today and the current forecast is mainly dry between now and racing. Temperatures are to possibly drop to -2 degrees tonight but if the forecast is correct I would be hopeful that the track will be fit for racing tomorrow.
"We will have a further inspection to assess the situation at 7.30am tomorrow morning."
