A status yellow rainfall warning is in effect across Munster and Connacht, as well as Donegal, Cavan and Monaghan.
An earlier national alert has been amended with a warning for Leinster to come into effect from 11am this morning.
Met Eireann is warning of very heavy rain at times with the chance of flooding in parts.
The alerts will run until tomorrow.
It’s as cooler weather looks set for the winter, but a local forecaster says there’s no reason to start worrying yet.
There’s a weather phenomenon called La Nina which sees a periodic cooling of ocean surface temperatures in the Pacific Ocean that can affect the weather here.
