FRIDAY'S race meeting at Ffos Las is in some doubt.
The fixture is subject to a 7.30am inspection on Friday morning.
Officials at the Welsh venue must assess conditions in case the track is waterlogged.
The going is currently heavy.
Clerk of the course Tim Long said: "We had a large amount of rain on Tuesday but we are raceable.
"It's heavy ground, but there are forecasts which suggest we could have a large amount of rain today.
"We just feel it's correct to make people aware of what's going on."
