Carlisle's Wednesday meet in doubt
Wednesday's meeting at Carlisle is subject to a further inspection at 8am on Tuesday.
A 2pm check proved inconclusive as a thaw is taking place but conditions will still need to improve dramatically.
Acting clerk of the course Kirkland Tellwright said: "Things are improving, it is just a question of whether they are improving fast enough.
"You'd be a brave man to call it off at this stage, but at the same time, you'd be a brave man to say it will go ahead looking at the forecast.
"We're forecast -2C for tonight and it could be colder still on Tuesday night, so we'll just have to see.
"We'll take it one step at a time."
