Motorists are being warned to take extra care across the country today as torrential rain causes localised flooding.
Several roads have already been flooded since early, particularly in the south and south east.
The N11 Dublin/Wexford Road in Enniscorthy has been closed on the Wexford side due to flooding, while several roads across Wicklow are affected including around Glendalough.
There is flooding on the Lower Road in the Strawberry Beds. Dublin Bus has also reported that there are a number of diversions in place due to flooding.

Met Eireann yesterday issued a status orange rainfall warning for Dublin, Louth, Wexford, Wicklow, Meath and Monaghan, which remains in place until Friday morning.
“A spell of heavy rain today followed by another spell of heavy rain tonight will give rainfall accumulation of 40 to 60 mm with localised flooding likely,” it said.
