Luxembourg's meteorological service has issued two alerts for Sunday: a yellow warning due to elevated temperatures and an orange warning due to elevated ozone concentration.

The yellow heat alert will be in place in the entire country from 1pm to 7pm. According to Meteolux predictions, temperatures are expected to range between 30°C and 32°C, and may even reach 33°C alongside the Moselle river.

The forecast also warns that ozone levels may exceed the European information threshold of 180 µg/m³. Meteolux has therefore issued an orange alert.

Although rain if forecast for Monday, Luxembourg's meteorological service only anticipate 3-5 litres per square metre.
