Severe thunderstorms swept through central Belgium on Saturday morning, causing multiple roof fires, street flooding, and flight delays at Brussels Airport [1, 3].

The storm's intensity disrupted critical transportation hubs and residential infrastructure, signaling a period of extreme weather volatility for the region.

The Royal Meteorological Institute (KMI) said that unstable atmospheric conditions led to the heavy rain, hail, and intense lightning [1, 2]. The impact was most severe in the Flemish Brabant province and the Mechelen area, where emergency services responded to various crises [1, 3, 4].

Lightning strikes ignited several roof fires across the region [3, 5]. Simultaneously, torrential rainfall caused streets and basements to flood with water and mud [1, 4]. In some areas, the water levels reached their highest point since 1974 [4].

Brussels Airport experienced significant operational disruptions as the weather system moved through [3, 5]. The storm caused flight delays, forcing authorities to manage the backlog of aircraft and passengers during the peak of the instability [3, 5].

Local residents in Flemish Brabant reported flooded streets and debris from the storm [2, 4]. Emergency services worked throughout the morning to secure the affected areas and address the fire hazards caused by the electrical storms [1, 3].

The KMI said that the weather would remain unstable for the remainder of the weekend [5]. Residents have been advised to remain cautious as further precipitation and lightning are possible.

“Lightning strikes ignited several roof fires across the region”

The recurrence of historic water levels and the severity of the lightning strikes suggest an increase in extreme weather events within the Belgian interior. The disruption of Brussels Airport highlights the vulnerability of regional transport infrastructure to sudden atmospheric instability, which may necessitate updated emergency protocols for the Flemish Brabant and Mechelen regions.
