Snow issues at Lingfield
Lingfield's meeting on Tuesday must pass a 2pm inspection on Monday.
Clerk of the course Neil MacKenzie Ross will assess conditions due to the prospect of further snow at the Surrey circuit.
Saturday's fixture at Lingfield was abandoned due to snow.
MacKenzie Ross said: "It's snowing again (on Sunday morning), but we have all day on Monday to prepare for Tuesday.
"Looking at the forecast, though, there is quite a real threat of snow on Monday afternoon.
"That could send us back to square one."
