Around 20,000 ESB customers are without power this evening across the southern part of the country due to adverse weather conditions.

A spokesperson for ESB Networks said lightning strikes were the main cause of the outages which stretch from the west coast to the east coast.

The main areas affected are Cork, Clonakilty, Dunmanway, Bandon, Gorey, Enniscorthy and Thomastown.

Due to the poor weather conditions, repair crews will not be able to restore power during the night.

ESB Networks said their crews will be out from first light and they hope to have most customers restored by lunchtime.
