A high temperature weather warning remains in place in 13 counties until Sunday, with temperatures possibly reaching the low 30s next week. The yellow warning has been issued for Carlow, Kildare, Kilkenny, Laois, Longford, Meath, Offaly, Westmeath, Wexford, Cork, Limerick, Tipperary and Waterford until 7am on Sunday. Met Éireann has warned of heat stress, uncomfortable sleeping conditions and possible forest fires. Uisce Éireann has also called on the public to reduce hosepipe and power-hose use for as long as the hot, dry weather continues as treated drinking water use remains “exceptionally high”.“Night-time restrictions in the Greater Dublin Area are under active consideration if water use is not reduced,” it said.The National Directorate for Fire and Emergency Management said it was co-ordinating with key stakeholders in preparation for a “prolonged period of very warm weather”. Minister for Housing, Local Government and Heritage James Browne said the hot spell will place additional pressure on people, services and local water supplies. “I am asking the public to look out for those who may need assistance and use water responsibly, follow the advice of the HSE, Met Éireann and the emergency services. Small precautions taken now can significantly reduce the risks,” he said. People enjoying after-work drinks outside McCafferty's at the Barge, in Dublin, on Friday. Photograph: Sam Boal/Collins
