The Portuguese Met Office has said the yellow alert will remain in force until 10pm tonight, but with thermometers set to rise on Wednesday, the advisory is set to be renewed again this evening.


The alert means that people should take additional are when exercising outdoor activities.


This was followed by seven regions being placed at extreme risk levels due to expected UV radiation exposure, while 17 others, including the Algarve and Lisbon are on a very high risk level.
