Officials at Wincanton will stage an 8am inspection on Thursday to assess the prospects of their St Stephen's Day fixture going ahead.
The course is currently covered in five inches of snow and with temperatures not forecast to rise any time soon, clerk of the course Barry Johnson is pessimistic.
“It’s not looking good as there is not really any sign that the snow is going to thaw much before Boxing Day,” said Johnson.
“There is no point prolonging things. We’ll speak to the forecasters again Thursday morning, and if they give us a glimmer of hope, we’ll sit tight.
“But there is no point everybody declaring to run if there is absolutely no chance of racing going ahead.”
