The IRM predicts amounts of precipitation between 10 and 15l/m² in the provinces of Liège and Namur. In the province of Luxembourg, it will be quantities oscillating between 15 and 20l/m², even locally up to 25l/m² for extreme values. It is not until Sunday morning that the active frontal system will leave our territory.
The Eau Noire and its tributaries are also added to the rivers in the pre-flood alert phase, according to the update of the Hydrometry portal of the Walloon public service (SPW). They join the Eau d’Heure, the Haute and Basse Sambre, the lower Ourthe, the Vesdre, the Amblève, the Our, the Senne, the Viroin, the Basse and Haute Lesse, the Haute Meuse downstream and upstream, the Sûre, the Basse, Moyenne and Haute Semois, the Chiers, the Vierre and their tributaries. The rest of the Walloon territory is considered to be in the “normal” phase.
