Poland issues nationwide heatwave and storm warnings FAST-MOVING
The Institute of Meteorology and Water Management (IMGW) has issued third‑degree heat alerts for 13 voivodeships, with temperatures expected to reach 33‑38 °C on 6 August 2026. Simultaneously, second‑degree storm warnings covering most of the country warn of heavy rain (30‑40 mm), hail and wind gusts up to 90‑95 km/h, potentially causing local flooding, tree damage and power outages.
The Government Security Center (RCB) sent SMS alerts to residents of 14 voivodeships, urging people to avoid open spaces and prepare for possible electricity interruptions. A hydrological warning was also released for the Vistula river basin, noting a 60 % chance of rapid water‑level rises in smaller rivers and urban catchments.
The combined heat and storm threat affects major cities including Warsaw, Łódź, Gdańsk, Katowice and Bielsko‑Biała, with emergency services on standby for fire risks, road disruptions and infrastructure strain.
