That rain will extend into Connacht and Leinster by the evening. Localised flooding is possible, especially in Munster and Leinster. Light to moderate east to northeast winds will strengthen fresh to strong. Highest temperatures of 10 to 14 degrees.

Tonight will continue wet and breezy, though it'll be windier in south and southeastern counties.

Any lingering rain will clear eastern counties by around mid-morning. Sunshine and well scattered blustery showers elsewhere will follow for the rest of the day, mainly affecting western counties.
