Warsaw underpass floods after overnight storm, water ankle-deep, weather warnings for Mazovia

Flooding at Warszawa Zachodnia

On Thursday morning, 11 June 2026, overnight downpours turned a pedestrian underpass beneath Jerozolimskie Avenue into a waterlogged corridor. The tunnel, which connects Warsaw’s Western Station with Park Pięciu Sióstr, was ankle-deep in water according to videos shared on social media. One commuter who navigated the passage by bicycle described the chaotic scene: he heard people shouting at each other “Don't go there, there's no way through!” and compared the atmosphere to a zombie invasion film. The Municipal Roads Authority (Zarząd Dróg Miejskich) is responsible for the underpass and was contacted for comment.

“Rainfall brings localised flooding. This is how the Western Station looked today in the morning.”

Warnings and regional impact

The Institute of Meteorology and Water Management (IMGW) had issued a first-degree alert for Mazovia and several other voivodeships, forecasting moderate to heavy rain, thunderstorms, and wind gusts up to 60 km/h. Predicted 24-hour totals ranged from 20 to 30 litres per square metre, with local peaks reaching 45 l/m². The warnings remained in force until 1 p.m. on Thursday. Beyond the station area, flooding was also reported on Płochcińska Street in Warsaw’s Białołęka district, where standing water forced drivers to slow down and seek alternative routes. Tram tracks in the city centre were also submerged, further complicating the morning rush.

A recurring challenge for the capital

The June 2026 flooding echoes severe weather episodes in recent memory. In summer 2024, violent storms swamped streets across Warsaw, temporarily closing sections of the S8 expressway and triggering around 800 fire brigade callouts. Mayor Rafał Trzaskowski at that time urged residents to rely on public transport and avoid flooded areas. In January 2026, freezing rain and snowfall caused similar disruptions, delaying buses, trams and trains. Thursday’s inundation once again highlighted the city’s vulnerability to intense rainfall and the strain on its drainage infrastructure.
