A blanket of dense fog is threatening a lot of the National football Leageu round two encounters but there has been no word of delayed throw-ins or cancellations yet.
Amazing images from right around the country have shown how slow the fog has been to lift.
The situation at Castlebar was looking very poor an hour ago but the fog has lifted.
Motorists heading to the games are advised to drive with caution.
Here are some of the fog pictures from today.
