Floods in the south of Luxembourg

The south of Luxembourg has been placed under awareness level orange floods from 09.09.2025 14:00 to 09.09.2025 17:00. The awareness level can be adapted or extended depending on the evolution of the situation.

The heavy rainfall during the past night has led to a rapid rise in water levels in the south and center of the country. At all gauging stations along the Alzette, the "Cote de vigilance orange" has been exceeded. At the Pfaffenthal and Steinsel stations, the "Cote de vigilance rouge" has also been surpassed. The peak water levels were reached during the morning and are currently falling, with this trend expected to continue throughout the day. By the afternoon, water levels at all Alzette stations are expected to drop below the "Cote de vigilance orange". Caution is still advised for any activities near water bodies.

Please take precautions and inform yourself on the right behaviour to adopt.
