Overnight storms will cause disruption for road and rail users this morning.
AA Roadwatch is urging motorists around the country to take care on the roads this morning following the heavy rain.
The worst affected counties were Dublin, Cork, Offaly, Wicklow and Westmeath with spots of flash flooding in parts.
Much of the water has receeded, but drivers are being warned of surface water on many roads.
There will be some disruption to train services also, as overhead cabling was damaged in Wicklow so DART services between Bray and Greystones are affected.
The Rosslare to Dublin Intercity train will also face disruptions travelling through Greystones.
