Lower Ourthe and tributaries
The flow stabilization phase expected on the lower Ourthe and its tributaries continues and is, as expected, slowed down by the arrival of a new rainy zone in the basin. This phase should continue overnight from Monday to Tuesday.
Given the hydrological observations and forecasts, the pre-alert phase is maintained in the basin until further notice and following the next observations.
Amblève and tributaries
The decline on the Amblève and its tributaries has continued since the morning but should be slowed down by the new accumulations of rain expected at the end of the day, with the possible consequence of a further slight increase in flows during the night from Monday to Tuesday. Given the hydrological observations and forecasts in this basin, the pre-alert phase is maintained there until further notice.
Mehaigne and tributaries
Although the tributaries of the Mehaigne are in the stabilization phase, the flood peak on the Mehaigne has not yet been reached and the flow continues to increase slowly. Hydrological forecasts seem to indicate that the pre-alert threshold should not be reached, the pre-alert phase is nevertheless maintained preventively until further notice.
Tributaries of the Haute Meuse
The flow rates of certain tributaries of the Haute Meuse (in particular le Bocq et Coal) crossed the pre-alert threshold during the day on Monday. These flow rates are in the stabilization phase. They nevertheless remain beyond the pre-alert threshold. From then on, the pre-alert phase is maintained for the tributaries of the Haute Meuse.
Upper Meuse upstream
Flows on the Haute Meuse are increasing. They should continue their slow growth in the coming days. The pre-alert phase is therefore maintained for the Haute Meuse (upstream and downstream).
Upper Meuse downstream
Flows on the Haute Meuse are increasing. They should continue their slow growth in the coming days. The pre-alert phase is therefore maintained for the Haute Meuse (upstream and downstream).
Lower Lesse and tributaries
The flow on the Lower Lesse and its tributaries reached its peak in the morning and began a slight descent. The risk of a delay in this decrease, or even a further increase in flow due to a new area of precipitation expected throughout the day cannot nevertheless be excluded, with a possible crossing of the pre-alert threshold during the course of the day. from Monday night to Tuesday. The pre-alert phase is therefore maintained in the basin until further notice.
Viroin and tributaries
Flows on the Viroin and its tributaries are in a stabilization phase which should continue in the coming hours, but nevertheless remain above the pre-alert threshold. The pre-alert phase is therefore maintained in the basin until further notice.
Chiers and tributaries
The decline is taking place on the Chiers and should continue for the rest of the night. Given current hydrological observations and forecasts, the pre-alert phase is maintained until further notice, and the situation remains under observation.
Upper Semois and tributaries
Flows on the Haute Semois and its tributaries reached their peak on the morning of Monday. They are currently in a stabilization phase which should then give rise to a decreasing phase during the night. Given the hydrological observations and forecasts, the pre-alert phase is maintained until further notice depending on the evolution of the observations.
Average Semois and tributaries
Flows on the Middle Semois continue to grow slowly. They should then stabilize at the end of the night. The pre-alert phase therefore remains maintained on the Middle Semois.
Haute Sambre
Flows on the Haute Sambre are in the stabilization phase. This stabilization phase should last through Tuesday. They remain high, justifying the maintenance of the pre-alert phase.
Seine and tributaries
Flows on the Senne are decreasing. The flow rates nevertheless remain high and the pre-alert phase is therefore maintained until further notice. The evolution of flow rates remains under surveillance.
Scheldt
Flows on the Scheldt are stabilizing. They should begin to decrease during the night from Monday to Tuesday. The pre-alert phase is maintained. The situation remains under surveillance and the greatest caution is required near watercourses.
Wind damage
On Monday, it was mainly the wind caused by storm Floriane which caused damage. HAS Bruxellesfirefighters intervened nearly 100 times and dozens of trees were broken or uprooted. HAS Liègechildren were injured by a sheet of metal in a school, others evacuated following the fall of a tree. HAS Oreye (province of Liège), a person found himself stuck in his car. The woman was in shock and her body was hypothermic.
HAS Nivellesa tree crashed into a car while Attit was on a house that a tree finished its fall.
