Storm Karl-Heinz, a powerful low-pressure system originating from Poland, has impacted Sweden, resulting in significant rainfall and widespread disruptions across various regions. As of today, July 29, 2025, the Swedish Meteorological and Hydrological Institute (SMHI) has issued orange warnings for southeastern Norrland due to anticipated rainfall of up to 100 millimeters in some locations, with Gotland expected to receive about 90 millimeters, surpassing the area’s typical monthly rainfall.
The severe weather has led to intense flooding, particularly on Gotland, with reports of downed trees and blocked drains causing significant property damage. Local emergency services in Visby, Gotland, reported multiple incidents of water damage, especially in areas like Othemsgatan and Birkagatan, where pumps are being deployed to alleviate flooding conditions. Traffic conditions are deteriorating, with major roads such as E4 experiencing obstructions and delays due to flooding, while public transport services in Stockholm, including the metro and tram systems, have faced disruptions after a tree fell on the rails.
As heavy rain continues to spread regionally, regions including eastern Svealand and Dalarna have been placed under yellow warnings for heavy rain, with predictions of 30 to 50 millimeters affecting daily life positively. Areas to the north, such as Norrbotten, Västernorrland, and Västerbotten, are also at risk from thunderstorms and local flooding, raising concerns about visibility and road safety.
Meteorologist Tony Fuentes warned residents to remain vigilant as storms may continue throughout the day, with forecasts indicating the possibility of extended rainfall and other hazards linked to the storm. Meanwhile, communities in affected areas, such as Bergsjö in Nordanstig, have been cautioned against swimming in local waters due to the discharge of untreated wastewater due to the storm's impact on sewage systems.
Officials continue to monitor the situation as the storm's unpredictable path complicates forecasts. Roads and public transport systems are being adapted to the conditions, while residents are urged to heed warnings and stay clear of flood-prone areas as the storm progresses.
