The alert thresholds have been reached since midnight at several stations on the Dyle and its tributaries following heavy precipitation, warns, in a new update during the night of this Tuesday to this Wednesday, the hydrometry website in Wallonia.
The Dendre and its tributaries are in the flood pre-alert phase. The other rivers in Wallonia are currently in a normal phase.
“The accumulations observed were particularly significant in Hainaut and Walloon Brabant where damage from runoff and exceedances of pre-alert and alert thresholds were observed. The levels should stabilize in the second half of the night,” further specifies the hydrometry site in Wallonia.
The heavy rains that fell on Tuesday afternoon in Walloon Brabant notably caused flooding in Chastre, Jodoigne and Mont-Saint-Guibert, as well as the overflow of the Hain in Walhain. Floods were also noted in Picardy Wallonia.
In Flanders, the alert threshold of two rivers was exceeded in the towns of Grammont and Zwalm, in East Flanders. Several other places in the Flemish Ardennes were also affected by the floods.
