Met Éireann has issued a weather warning with Storm Agnes set to make landfall on Wednesday morning.
The UK Met Office has named Storm Agnes, the first of the season, with Met Éireann and the Dutch weather service following suit.
Met Éireann’s yellow wind warning is from 7am on Wednesday to midnight on Thursday for Leinster and Munster.
It has also issued a status yellow rain warning for the counties of Carlow, Dublin, Kilkenny, Wexford, Wicklow, Cork, Kerry and Waterford for the same period.
The UK Met Office has also issued a yellow wind warning for Northern Ireland from 12pm tomorrow until 7am on Thursday.
Met Éireann forecaster Mark Rowe said the warnings may be updated as the exact path of Storm Agnes becomes known, possibly on Monday afternoon or during Tuesday.
Storm Agnes has the potential to bring gusts of up to 130km/h and torrential rain to parts of the south coast of Ireland.
A deep area of low pressure in the Atlantic will bring very strong winds and heavy rain to the UK on Wednesday.
Some weather models are showing more than 30mm of rain in parts of Cork and Waterford with heavy rain throughout most of the island on Wednesday.
Most models show the storm skirting the south coast at present with the worst winds out to sea, but the trajectory will not become clearer until closer to the event.
Aside from Wednesday, it will be a very mild week with temperatures of up to 18 degrees with scattered showers on Monday and Tuesday. Thursday and Friday look like being drier days.
