The English meetings at Huntingdon and Sedgefield on St Stephen's Day are subject to inspections.
Huntingdon's meeting is subject to a 12pm inspection on Christmas Eve.
The Cambridgeshire venue is partly flooded following 16 millimetres of rainfall on Saturday. More rain is also on its way in the next 24 hours.
Sedgefield must also survive an inspection at noon on Christmas Eve following torrential recent rain.
64 millimetres fell from Wednesday to Thursday evening was exacerbated by another 16mm on Saturday.
Although the forecast is favourable, there is currently standing water on the track.
Clerk of the course Phil Tuck said on Sunday morning: "The forecast has improved and it's windy today, which is helping to dry the track.
"We are 90% raceable, but there is a bit of standing water we need to get rid of. I'm certainly a lot more hopeful than I was a few days ago. If this wind keeps up, there'd be good chance we might be OK by tomorrow."
