A Status Yellow weather warning for counties Waterford and Wexford remains in place until midnight.
In these counties, Met Éireann said the flood risk is increased "due to high river levels and saturated ground".
Previous orange and yellow warnings have now expired.
Tonight will see outbreaks of rain and drizzle with clear spells and just a few showers in the west, Met Éireann said.
The forecaster said rain may linger over parts of the southeast for much of the night with flooding still possible in places and added lowest temperatures will be between 2C to 6C.
