Heavy rain is being forecast for the entire country tonight.
Met Éireann initially issued a status yellow rainfall warning for Leinster and Munster.
However, that's now been extended to the rest of the country.
Forecasters say the heavy rain will spread from the south this evening and tonight, extending to Connacht and Ulster later in the night.
Accumulations of 25 to 40mm are expected over a "relatively short time period", while spot flooding is likely.
