Navan's card on Saturday, featuring the Grade One Navan Novice Hurdle, is subject to a 7.30am inspection.
The track is due to race on Sunday, too, though three chases on that card have already been abandoned. One of the hurdle races due to be staged on Saturday has been divided and moved so there will be six contests.
The decision to hold a morning inspection ahead of Saturday's fixture was taken due to an unfavourable forecast.
The track is currently raceable, with the ground on the hurdle and bumper course described as soft to heavy.
The steeplechase course at Thurles has been found unfit for racing ahead of Sunday's meeting, with the situation being monitored.
There are also problems at Punchestown, where a fixture is scheduled for Monday.
An inspection was held on Friday and the course was found to be partly frozen and unfit for racing. It will be inspected again at 8am on Sunday.
Friday's meeting at Downpatrick was called off as the course was found to be unfit for racing following a 7.30am inspection. Snow was the main factor behind the cancellation.
