The prospects for racing at Bangor on Friday hinge on an inspection at 8am on Thursday due to the threat of waterlogging.
Both chase and hurdles courses are heavy, waterlogged in places, but the forecast for the next couple of days is for dry weather which should aid their cause.
Clerk of the course Andrew Morris is hoping that will allow the high river levels to drop, but at this stage he is "relatively pessimistic" because of the sheer volume of water.
"We had a wet weekend and then had 11 millimetres of rain on Monday and six millimetres last night," he said.
"The biggest issue we have had since December is the volume of water. The ditches and river levels are so high that the water has no chance to get away.
"We have got two dry days ahead of us which is great. The problem is we need the river level to drop to allow the drainage system to work.
"I'd be relatively pessimistic because of the volume of water that has to go, but equally if the river level does drop it will go fairly quickly."
