Thousands of homes across Northern Ireland were left without electricity last night while drivers struggled on flooded roads. Flash flooding hit the north west especially hard, and the atrocious weather even led to an Armagh swimming pool being closed. Northern Ireland Electricity told the Belfast Telegraph that 3,000 homes were without power at around 8.45pm after lightning struck transformers in Ballymena, Ballymoney, Lisburn and Campsie. The power cuts were spread sporadically throughout Northern Ireland, with no single area hit particularly badly. Engineers were last night working on repairing the damage. In Armagh the Orchard Leisure Centre informed customers its swimming pool and other leisure facilities were closed "due to heavy rain and conditions beyond our control". SDLP MLA for West Tyrone Daniel McCrossan said many of his constituents called to report cars trapped in flood water across different parts of Omagh, Strabane and Castlederg. Elsewhere, Derry City and Strabane councillor Graham Warke called for help for residents who had their gardens submerged in Primity Gardens in the Newbuildings area on the outskirts of the city. He also called for sandbags to be sent to a nearby care home. Last night he shared a photo on Facebook showing neighbours working together to prevent the flood water destroying the family homes. "This is what it is like when a community come to help a family," he said. "Honestly, I have never seen weather like it.
