Tipperary's Tuesday meeting has has been cancelled due to waterlogging.
The course endured 17 millimetres of rain Saturday night and Sunday morning, while further rain is forecast over the next 48 hours.
Sunday afternoon's meeting at Tramore was also cancelled after the course was deemed unfit for racing.
Heavy rain overnight forced officials to call off a seven-race card that was due to feature the Listed At The Races Chase.
The Co Waterford circuit is due to stage another meeting on Monday, but that is likely to be subject to an inspection.
The Irish Turf Club's press officer Cliff Noone said: "They've had no option but to cancel today's meeting as the track is waterlogged in places.
"There'll definitely be an inspection ahead of Monday's meeting.”
