Met Éireann expects wind warnings to be issued for Saturday night and Sunday as an 'exceptionally high supermoon' brings spring tides.
It issued a weather advisory for wind, as well as coastal flooding as the weather system heads for Ireland.
The advisory is in place until midnight on Saturday.
Forecaster Andrew Doran-Sherlock outlines what's in store in the next few days.
"We are in a period of exceptionally high astronomical spring tides even without any strong winds or heavy rain - there is the possibility of coastal flooding around high tide
"Even tomorrow there will be fresh and gusty southerly winds.
"Then on Saturday night into Sunday - there is some uncertainty in the details - but a depression is going to move close to Ireland, he said.
Tonight the sky is set to showcase the brightest supermoon of the year.
It's the third time there's been a supermoon this year, with the final supermoon expected in November.
October's supermoon is known as a 'Hunter's Moon' - as it marks the beginning of hunting season, while November's is known as the harvest moon.
