Officials at Catterick will stage an inspection at 8am on Sunday to assess the prospects of Monday's meeting going ahead.
The North Yorkshire circuit remains frozen and partially covered in snow, leaving clerk of the course Fiona Needham less than optimistic.
"The course has been frozen since February 3 and the ground is frozen solid at the moment. The only glimmer of hope is that it is due to get warmer from Sunday into Monday, but I fear it might be too little too late," she said.
"We'll review the forecast on Sunday morning and see if there is any point carrying on, but I'm not very hopeful of racing at this stage."
