The GAA have contacted all county panels to brief them that Saturday's Allianz League games will be rescheduled for St Patrick's Day or Bank Holiday Monday if they fall foul of the weather.
There is a yellow snow and ice warning for Donegal and a yellow rain warning for large parts of the country on a day when 20 Allianz Football and Hurling Leagues are scheduled to go ahead.
Traditionally the GAA try to avoid games on St Patrick's Day due to traffic and policing constraints, while Bank Holiday matches are famously poorly attended.
However they will have little option if the weather takes it toll tomorrow, with The Irish Examiner reporting that the Gaelic Players Association (GPA) contacted all squads to prepare them for the possibility of their games being refixed for Sunday or Monday.
After a week's delay in the Division 1 hurling fixtures, the GAA are intent on avoiding any further setbacks that would impact on April as a month solely for club fixtures.
As it stands, the Allianz Football League Division1 and 2 finals, as well as the Hurling League Division 1 final are fixed for Sunday, 31 March.
