Deadly 'heat dome' to hit Ireland as Met Eireann drops bombshell

A deadly 'heat dome' currently baking much of Europe is set to reach Ireland over the coming days.
The 40°C-plus temperatures claimed the life of a 34 year-old Dutch tourist in Mallorca earlier this week. The man died as a result of heatstroke, according to local media.
Temperatures across Ireland will not be similar to those currently sizzling parts of Spain, Italy, France and Portugal, however, it will still be unseasonably warm.
Irish based weather expert, Alan O'Reilly, the face behind Carlow Weather on X, described the heat in parts of Europe as "unusual".
"Here comes the real heat for Portugal, Spain and France from the weekend into early next week," declared Alan.
"Spanish Met Service has issued warnings for an unusual heatwave. The second half of the video shows France and some of England and Ireland. However Ireland won't see much of this hot weather but it will be a warm weekend and Monday here with a lot of cloud. If heading to the hotter spots take care."
The so-called 'heat dome' is due to hot air trapped by high pressure taking hold in Europe. Temperature maps show that the hottest parts over the next three days are in the east of Ireland with temperatures set to reach as high as 26°C.
