As a Polish cyclone approaches Sweden, severe weather alerts have been issued across several regions due to expected heavy rainfall and thunderstorms. The Swedish Meteorological and Hydrological Institute (SMHI) has announced a yellow warning for central Norrland, forecasting rain accumulation of 30 to 50 millimeters between 8 AM and 9 PM on July 28, 2025. This rainfall raises concerns about potential flooding, reduced visibility, and aquaplaning hazards on roads.

The cyclone is anticipated to impact areas including Öland, Gotland, and eastern Svealand on Monday evening. Additionally, thunderstorm warnings have been issued for eastern Norrbotten as well as parts of Västernorrland and Västerbotten. The thunderstorms pose risks of lightning strikes that can ignite fires, creating dangerous conditions for outdoor activities. Meteorologist Martin Kjell from Stormgeo has highlighted the significant risks involved with these storms, particularly for those engaging in outdoor recreational activities.

Following the expected precipitation, clearer weather is predicted for Wednesday. However, meteorologist Kjell noted that additional weather fronts are likely to move in later in the week, indicating a shift away from the warm summer conditions that have prevailed.
