France recorded its hottest May day on record, with further temperature increases expected as a 'heat dome' causes unseasonal warmth across large parts of Europe. Authorities have issued health warnings and implemented restrictions on outdoor work due to the extreme conditions.

France on Monday recorded its hottest May day on record, its weather agency said, forecasting that Tuesday would be even warmer as large swathes of Europe bake under unseasonal heat that is prompting officials to issue health warnings and order restrictions on outdoor work. Météo-France said the heatwave is likely to last at least until the end of the week.
