Heavy rain and strong winds continue to batter the country this morning, but road conditions are improving.
In Wicklow and Dublin the earlier closure of the M11 near the Bray North exit has caused long delays, though it has now reopened to northbound motorists.
Wicklow: M11 reopened n/bound. S/bound still closed after J5 Bray North. Divert via Wilford R/A south of Shankill. http://t.co/9de5SKCdi8— AA Roadwatch (@aaroadwatch) March 22, 2013
Traffic is also barely moving on the M50 southbound from J16 Cherrywood to past the M50/M11 Merge as a result.
Elsewhere in Dublin, flooding in Cabinteely and on Pottery Road in Dun Laoghaire is causing problems.
Meanwhile in Cork, there continues to be some lose debris in Blackpool, and care is also needed in counties Wexford and Waterford.
