A "multi-weather hazard event" is threatening to wreak havoc on the weekend's sports schedule.
The All-Ireland club senior football semi-finals on Sunday. An All-Ireland junior semi-final and the All-Ireland intermediate semi-finals tomorrow are all in danger of cancellation.
A number of challenge games that are due to assist in the adopted playing rules in Gaelic football for the first time are also in jeopardy because of the cold snap.
Meanwhile, an inspection will be held at Naas racecourse on Sunday morning ahead of that afternoon's scheduled card. Whereas, racing on Saturday in Cork is under review with a course inspection due at 8am.
There are no scheduled united rugby championship games this weekend.
