Wetherby on frost alert
Tuesday's jumps fixture at Wetherby is subject to an 8am precautionary course inspection on raceday morning.
Executives at the Yorkshire venue are carefully monitoring the weather in case of a sharp overnight frost.
Wetherby said in a statement that an unexpected frost on Monday morning "left a few crusty areas" on the track after overnight temperatures dropped to minus 2.5C.
The official going is soft, heavy in places.
