Met Éireann has issued another Status Yellow high temperature warning as Ireland's heatwave continues, with temperatures expected to reach 29C this week and forecasters saying the hot spell could last into next week.
The warning comes into effect at 1pm today (Monday) for Cork, Kerry, Limerick, Galway and Mayo, where temperatures could exceed 27C. It will remain in place until 7am on Wednesday.
Night-time temperatures are also expected to remain unusually high, with lows staying above 15C.
Speaking on RTÉ Radio 1's Morning Ireland, Met Éireann meteorologist Rebecca Cantwell said there is no immediate end in sight for the hot weather.
"The end is not near, not yet. This heatwave could last into next week. It's looking like great weather."
She added: "The sun is very hot at the moment, along the east coast here we're in an easterly flow so it is a little cooler than the west.
"Even as that high pressure shifts slightly over the next week, we're going into a northern flow, so it will get very warm again."

The national forecaster has warned of a number of potential impacts from the prolonged spell of hot weather, including heat stress, uncomfortable sleeping conditions, an increased risk of forest fires, drought, and water safety issues as more people visit beaches, lakes and other waterways.
Meteorologist Deirdre Lowe has also indicated that further high temperature warnings are likely to be issued later this week.
"The very warm or hot weather is set to continue this week," she said in Met Éireann's daily weather podcast.
"With the fine weather, do remember to stay hydrated, sun smart and stay safe when around the water," she added.
A nationwide hot weather advisory also remains in place until midnight on Friday.
The heat has already broken records, with Valentia Observatory in Co Kerry reaching 30C on Sunday – its highest temperature since records began. The previous record of 29.8C was set in August 1995.

Looking ahead, Monday will remain dry, sunny and very warm.
According to Ms Lowe, temperatures will range from 24C to 29C across Munster and Connacht, with the highest values expected in western and southwestern coastal counties covered by the Status Yellow warning.
Meanwhile, Leinster and Ulster can expect highs of 20C to 24C, with cooler conditions continuing along the east coast.
Tuesday is expected to bring another dry day with widespread sunshine, although some cloud and the chance of a shower may develop in the southwest later in the day. Temperatures are forecast to reach between 23C and 29C, with the warmest weather again in the west.
Looking further ahead, Met Éireann says the heat is expected to continue through the rest of the week, although the combination of heat and humidity could trigger isolated showers or thunderstorms.
"The heat and humidity could spark off some showers or thunderstorms as well. Most likely, if they do occur, will be in the south, Midlands and the west," Ms Lowe said.
"Throughout the week, temperatures will widely reach the mid to high 20s by day, with warm and possibly tropical nights too, meaning they may not fall below 15 or 20C," she added.
