Met Eireann has issued a Status Yellow rain and wind warning for the entire country with heavy rain and a risk of flooding from Tuesday.
The 17-hour Status Yellow alert begins at 10pm on Tuesday.
A forecaster for Met Eireann said: “Heavy rainfall on Tuesday night and Wednesday, possibly turning wintry in places, will be accompanied by strong to near gale force and gusty southerly winds.
“This will lead to hazardous driving conditions and localised flooding.”
It comes as the national forecaster posted another Status Yellow alert for 10 counties from 4am until 3pm on Tuesday.
The affected counties are Clare, Cork, Kerry, Limerick, Waterford, Donegal, Galway, Leitrim, Mayo, and Sligo.
Met Eireann said: “Strong to near gale force and gusty southeast to south winds on Tuesday morning and afternoon. These winds will be accompanied by heavy rain clearing to squally showers through the afternoon, with hazardous driving conditions and localised flooding possible.”
The warnings have been issued ahead of a low pressure system which is forecast to move up from the south on Tuesday.
In its latest outlook, Met Eireann said: “Turning windy overnight but largely dry initially with some clear spells. Lowest temperatures generally of 0C to 3C with a touch of frost in places. Milder in southern parts with patchy light rain and drizzle pushing northwards.
“Fresh to strong and gusty southeasterly winds will develop, increasing near gale force in the southwest. Towards morning, a band of heavy rain will move in from the southwest and extend over much of Munster by morning."
