According to Dehenauw, there is at least a 65 percent chance that it will be 40 degrees in those two provinces on Tuesday, and that in at least a quarter of the surface of West Flanders and Hainaut. “However, it remains a borderline case that is now leaning towards red,” he says.
Code red means that certain measures must be taken. For example, people have to drink a lot and keep their salt levels up. In addition, they should also rest a lot, stay in a cooled room, avoid direct sunlight and use damp cloths in case of dehydration, according to the website of the RMI. In the rest of the country, code orange applies, just like today.
In 2019 and 2020, the RMI also announced code red due to heat. No heat warnings were issued in the summer of 2021.
