Navan faces inspection on Saturday morning
Navan's seven-race card on Saturday, which features the Grade Two Webster Cup, must pass a 7.30am inspection after a period of heavy rain.
Clerk of the course Paddy Graffin said: "Following a further 10mm of rain since our update at 8am this morning and with the forecast for further rain today, there will be a 7.30am inspection tomorrow morning.
"We've had 27mm of rain since yesterday morning but unlike other parts of the country, we have avoided the snow. The track is fit for racing at present but we do have a small amount of surface water in places.
"At this point we've already had more rain than was forecast and Met Eireann is suggesting there could be still another 8-10mm to come today. However, some other forecasts are slightly more favourable, so we'll see what the rest of the day brings and assess the situation at our inspection tomorrow."
