It comes as thousands of people descend on Stradbally, Co Laois, for the start of the Electric Picnic music festival.
The festival kicks off today for the first time since 2019, having missed two years due to the Covid-19 pandemic.
Met Éireann said today will start off rather cloudy with some hazy sunny spells.
However, persistent rain will develop in Atlantic coastal counties during the afternoon and spread eastwards later this evening.
It will be cloudy and wet overnight with outbreaks of rain, which will be heavy at times.
The rain will push northeastwards tomorrow morning, but elsewhere there will be a mix of sunny spells and showers, with some of the showers heavy and thundery.
The UK Met Office has issued a Yellow rain warning for Antrim, Armagh, Down, Tyrone and Derry and said that occasional periods of heavy rain tomorrow may lead to some travel disruption.
The warning will be in operation from midnight tonight until midnight tomorrow.
The Road Safety Authority urged drivers to be cautious while using the roads over the weekend due to the high rainfall expected.
It warned that during a prolonged dry spell "a build-up of oil and rubber deposit develops on the road".
"When the weather breaks, this deposit mixes with rainwater and the road becomes hazardous," the RSA said in a statement.
"The resulting greasy road surface increases stopping distances and the risk of a skid."
The RSA advised road users to slow down and to be aware of the danger of aquaplaning, especially on roads with speed limits of 100 km/h and 120 km/h.
