Prepare for rain tomorrow, and lots of it! But there's better news for the big game on Sunday...
If you're out and about tomorrow be pack the umbrella and the rain jacket.
The remnants of Atlantic Storm Ernesto are set to reach Ireland on Saturday evening, bringing with it a flurry of wind and rain.
Met Éireann says heavy rain will develop in the afternoon "along the Atlantic Seaboard and will become widespread early Saturday night."
According to weather service AccuWeather, winds from Ernesto - which is currently over the Atlantic Ocean - will generate "significant swells over part of the north-central Atlantic."
Despite the rough weather, temperatures will still be high with Munster and Leinster seeing highs of 25 degrees, while the north and west will see temperatures between 18 to 20 degrees.
And it's good news for the big game on Sunday with Met Éireann predicting Sunday will begin with rain, but as the day progresses it will become brighter and drier in most places, with temperatures in the high teens to low 20s.
Here's hoping the rain stays away from Croke Park!
