Roads in Cork city and the south east have reopened and power has been restored to over 4,000 homes around the country, but many areas are still under water as the threat of further storms remains.

Met Éireann said today that another 24 hours of stormy conditions will lead to further structural damage and flooding is expected.
Rainfall totals in excess of 50 mm are predicted over a wide area, leading to further severe flooding, due to the already saturated ground, Met Éireann said.
High seas and tides, could lead to coastal flooding, particularly in the south and east of the country, it added.
A number of areas in Dublin, including Santry, Malahinde, Portmarnock, Clontarf and Ringsend, are reported to be experiencing flooding. Flooding on the main road in Blackrock resulted in a five-car accident this morning outside the Blackrock Clinic. No one was injured.
Many of Cork city's roads, which were impasssable due to flooding yesterday evening have reopened, as have roads in the county.
However further flooding occured this evening at high tide. Three people had to be rescued in Mallow this afternoon when they drove into floodwaters after the River Blackwater burst its banks, leaving parks under ten feet of water.
In Waterford city, the quay has reopened as have roads in Wexford town.
Most of the storm damage was structural with hundreds of homes and businesses flooded in parts of Cork, Wicklow and Waterford city.
Iarnród Éireann has advised passengers that the rail line between Wicklow and Greystones is closed, as is the Cork to Cobh commuter line.
In the North, there were problems along coast roads in Antrim and Down. The PSNI are advising caution as many roads are partially flooded.
Around 5,000 electricity customers lost power through the night as lines blew down in high winds gusting to up to 80 mph. Some 4,000 customers have since been reconnected. The remaining 1,000 customers affected in parts of Enniscorthy, Wexford, Carlow and Killkenny, would have power restored today, the ESB said. Some 200 ESB engineers worked overnight to restore services.
