Waterlogging had been the main concern at the Welsh venue, but officials at the track were heartened by conditions after an early-morning assessment.
Fifteen millimetres of rainfall during Friday was exacerbated by another sharp shower last night, but the ground is still raceable.
The going is currently heavy for a fixture which features the Burns Pet Nutrition Welsh Champion Hurdle.
Ffos Las general manager Tim Long said: "We've had plenty of rain, but we are on - and that's the main thing.
"It's going to be tough going out there - there's also quite a fair wind to deal with - but we are good to go.''
At Wetherby, a planned inspection was cancelled well before it was due to take place with officials happy with the conditions of the Yorkshire course after a relatively dry night.
Clerk of the course Jonjo Sanderson said: "The rain came as predicted, but 10mm is not an awful amount of rain and it had stopped (raining) by around 7.30pm.
"That gave the ground plenty of time to soak up the rain and drain it away.
"It's good news - I'm very pleased."
The card's feature race is the Grade Two totepool Towton Novices' Chase, while the current going is heavy.
Sandown was the last of the three to be given the green light having survived a 7.45am course inspection and goes ahead as scheduled.
Heavy rain on Friday had put the fixture in major doubt, but officials at the Esher circuit were happy with what they found at daybreak.
Clerk of the course Andrew Cooper told The Morning Line: "We had 17 millimetres (of rain) up to about 3am.
"Everyone who has been out here this morning haven't given it the thumbs-down.
"The problem area has been between the second-last and the last fence, but it's safe and we're happy to give it a go."
The all-chase is due to feature the Grade One Betfred TV Scilly Isles Novices' Chase.
