“Our crews, alongside local authority teams, are working in freezing conditions to access water-treatment plants and pump stations. We are working to restore supplies affected by bursts and power outages,” the utility said in a statement. Around 17,000 people in Co. Tipperary are currently without water.

Meanwhile, An Post has suspended letter and parcel deliveries across most routes in Cork, Kerry, Kilkenny, Limerick, Tipperary, and parts of Wicklow due to severe weather.

“If conditions improve, deliveries will resume where it is safe to do so,” An Post said in a statement. “Many Post Offices in these counties are also affected. While some may reopen later, many will remain closed on Monday.”

Met Éireann has extended its low-temperature and ice warning until midnight on Thursday. Initially, the warning was set to expire at noon on Thursday.

Heavy snow fell in some areas on Sunday, and a Status Yellow warning for low temperatures and ice remains in effect nationwide.

The Road Safety Authority (RSA) is urging motorists and pedestrians to exercise extreme caution as rain, sleet, snow, and ice continue to create hazardous conditions. With extremely low temperatures recorded in some areas, RSA spokesperson Aoibhinn Twomey advises against travel unless absolutely necessary.

Met Éireann warns of potential impacts from the cold snap, including icy roads, travel disruptions, and dangerous conditions. The public is advised to stay updated via weather alerts and local guidance.

Severe weather has also led to the cancellation of HSE services in several counties. While most services continue as normal, outpatient appointments and day services in Cork, Kerry, South Tipperary, Laois, and parts of the Midwest have been canceled due to hazardous travel conditions.
