Powerful thunderstorms in the counties of Stockholm and Uppsala left thousands of households without power on Thursday morning. Multiple incidents of flooding and other alarms related to the weather have also been reported.
But the most dramatic scene was found in Saltsjöbaden, just outside of Stockholm.
"It was an unmanned boat moored in the lake," Björn Wrandel at the Sea Rescue Centre told news agency TT. "Apparently the lightning struck a huge hole in the boat and it sank incredibly quickly."
No one was injured in the incident.
Sweden's weather agency has issued a warning for extreme thunderstorms in Stockholm and Uppsala during the morning.
