Friday's meeting at Limerick is subject to an 8am precautionary inspection due to the threat of overnight rain.
The course is currently raceable but a decision will be made well in advance of the first race that is due off at 12:35pm.
Elsewhere, tomorrow's meeting at Leicester will also need to survive an 8am precautionary inspection.
The going is currently heavy on the hurdles course but soft on the chase course with heavy patches.
Currently raceable, clerk of the course Jimmy Stevenson has been forced to call the inspection due to an adverse weather forecast with rain due in the morning.
Stevenson said: "It's purely precautionary at this stage as I've just walked the course and we are perfectly raceable.
"We've had nine millimetres today that we weren't really expecting but it's taken it well.
"More rain is forecast from 4am and we just hope there's not much as it could rain for up to four hours."
