If the unending rainfall is no longer enough to signal winter's imminent arrival, then the intended reappearance of the likes of Trifolium and Joncol at Punchestown surely is.
Yesterday's intriguing spread at the Kildare venue was lost after an overnight deluge left the track hopelessly waterlogged.
But it will be fascinating to see if Trifolium can show the sort of progression that one would expect from last year's productive novice campaign in the Ryan's Cleaning Events Specialists Hurdle on today’s Punchestown card.
The presence of Jessica Harrington's Citizenship, successful in the Boylesports.com Hurdle in January, should help to ensure that the six-runner Grade Three is not one-sided, but Trifolium is the horse with the most scope to improve.
In a busy first term with Charles Byrnes, the Gigginstown Stud acquisition won three in heavy going.
Third on drier ground in the Supreme Novices Hurdle at Cheltenham, Davy Russell's mount then fell just short to Alderwood at the Festival here in April.
However there was no shame in losing to Tom Mullins' up-and-comer.
The champion jockey might also take the maiden hurdle on Mouse Morris' point-to-point winner Rule The World.
