There will be an inspection at Wexford at 10 am on Tuesday ahead of Wednesday's fixture.
IHRB Clerk of the Course Paul Moloney said: "Since our update at 8 am this morning we have had 15mm of rain at Wexford and, unfortunately, now the track is waterlogged in places and, therefore, unfit for racing.
"In the forecast this morning, we were due to get approximately 21mm in total before racing, but having had 15mm already, the latest forecast suggests we could get another 18mm up to race time.
"Due to the track being waterlogged, and with the revised forecast, we will now inspect at 10 am tomorrow (Tuesday) to determine if the fixture on Wednesday can go ahead."
