Irish people travelling to parts of Europe are being warned to expect dangerously hot temperatures.
Most of France as well as parts of Belgium, Luxembourg and the Netherlands are bracing themselves for temperatures of up to 40°C this week.
An orange level heating warning is in effect for large areas of France, only weeks after record breaking temperatures were recorded in the country.
The warmest weather is expected on Thursday, reaching as high as 42°C in Paris.

A similar warning has been issued for Brussels, where forecasters are predicting temperatures of up to 38°C tomorrow.
Pat Dawson from the Irish Travel Agents Association (ITAA) is reminding those travelling to affected areas to stay safe.
He said: “Our members are advising holidaymakers staying in affected areas to stay hydrated throughout their stay and to avoid direct sunlight during the hottest periods of the day.
"We are encouraging all travellers to follow the advice of the local authorities which are implementing measures to tackle the extreme heat.”
Meanwhile, parts of the UK are also experiencing a heatwave this week.
