Following further light snow and with no improvement in conditions, the fixture at Thurles has been cancelled.
The meeting will instead take place on Wednesday with fresh declarations possible until 10am tomorrow (Monday) morning, the Irish Horse Regulatory Board said.
The fixture at the Co Tipperary venue was due to feature two Grade Two races, the Coolmore N.H. Sires Kew Gardens Irish EBF Mares Novice Chase as well as the Horse & Jockey Hotel Chase which was due to see the likes of Battleoverdoyen and Allaho clash.
Following a first inspection at 7.30am a second check was called for 9am with snow beginning to settle on the track. However, with no improvement in the conditions a decision was taken before the scheduled inspection to call the meeting off.
A statement from the IHRB read: "Following a second track inspection at Thurles this morning, the track remains unfit for racing due to snow.
"With no improvement and further snowfall between inspections, the fixture scheduled to take place this afternoon has been cancelled."
The board also confirmed that Navan's meeting, which had been postponed yesterday, will now take place on Friday, with new entries allowed until 10am tomorrow morning.
In the UK, the meeting at Hereford also fell foul of the wintry conditions.
