Update from the Joint Operational Command Post (PCO-C) – exceptional rainfall and flooding (09.09.2025)

The Joint Operational Command Centre (PCO-C) met late this morning via videoconference to review the situation following the heavy rainfall on Monday night and Tuesday morning.

Exceptional amounts of rain were recorded by MeteoLux and AGE, with peaks reaching 149 l/m² in Mersch and 123 l/m² in Findel within 12 hours – thresholds never before recorded.

These weather conditions required a significant mobilisation of emergency and security services:

Forecasts and vigilance

After a night of heavy rainfall, the morning began with very cloudy skies and a few more showers. According to MeteoLux forecasts, only light and scattered rain is expected over the next few days, with no significant impact on the situation.

Hydrological monitoring

Although the weather is expected to gradually improve, the levels of some rivers could still rise very slightly over the next few hours . Water levels on the Alzette remain high and this situation is expected to continue for a few hours before gradually starting to fall.

The AGE has lifted all alerts for the north of the country, while the south remains classified as red.

The PCO-C has decided to end its activation following the general stabilisation of the situation. However, the relevant services remain on standby and will closely monitor the evolution of water levels in the coming hours.

About the Joint Operational Command Post (PCO-C)

As part of the government's crisis management plan for severe weather and flooding, the Joint Operational Command Post (PCO-C) was activated on Monday evening at 11.30 p.m. at the National Crisis Centre in Senningen, following the triggering of a red alert.

The JOC brought together the main players in crisis management: the Grand Ducal Fire and Rescue Corps (CGDIS), the Grand Ducal Police, the National Roads Administration, MeteoLux, the Water Management Agency (AGE) and the High Commission for National Protection (HCPN).

The main tasks of the PCO-C are to analyse, together with experts from the assessment unit (CERI), the meteorological and hydrological situation and possible scenarios for its development, to centralise human and material impacts and operational needs, and to coordinate inter-service interventions.
