PUBLIC transport services are returning to normal after heavy overnight rain caused chaos for rush hour commuters.
Counties Dublin, Wexford and Wicklow were the worst affected by flooding with many roads left impassable after up to 35mm of rain fell.
Motorists are advised to only drive through water if they know it’s not too deep for their car and to reduce their speed.
Routes on the northside of Dublin were among the worst affected.
AA Roadwatch reported that conditions have improved significantly on the M1 southbound at Junction 4 Donabate.
However, flooding still remains a problem at Blake’s Cross and at the junction of the Old Swords Road and the Dublin Road. There is also flooding further south at the Seatown roundabout.
Gardai have also advised drivers to take extreme care on Hearse Road in Donabate due to flooding while the Old Portmarnock Road is impassable at the trotting track between Malahide and Portmarnock.
Dart and rail services, that were previously curtailed due to flooding at Sandycove, have now largely returned to normal, however Irish Rail warned that there could still be delays of up to 15 minutes to some services.
