Revellers heading to Electric Picnic are being warned to prepare for "all eventualities" this weekend.
The music festival begins on Friday in Co Laois with a record 70,000 people attending after a two year COVID-hiatus.
However, the weather forecast mightn't be music to everyone's ears - as this year's festival could turn into a 'mudfest' due to heavy overnight rain.
A status yellow rainfall warning has been issued for the entire country from 9pm on Saturday until midday Sunday.
While a weather advisory is in place for wet and windy conditions across the country from 7pm on Friday until 7pm on Monday.
Matthew Martin is a forecaster with Met Éireann. He told Newstalk Breakfast things don't look great.
"For today certainly it doesn't look too bad initially for much of the day.
"But it's really going to deteriorate later this evening and tonight - and then the weekend is looking quite wet at times.
"Whilst there's going to be heavy rain at times, there are going decent dry periods as well.
"So it's not all bad - but there is that possibility that there could be some localised flooding.
"It certainly is not ideal conditions".
"Obviously you're going to have to be prepared for all eventualities when you head down to Stradbally," Martin said.
"It's just unfortunate now, it looks like low pressure is going to be the dominant factor of our weather - really for the next week or so.
"It's just bad timing, I guess", he added.
