STOCKHOLM, Sweden — Hurricane-strength winds whipped across southwestern Sweden Sunday, leaving more than 100,000 households without power and causing major disruptions in train and boat traffic across Scandinavia, officials said.

The bridge connecting Sweden and Denmark was shut down to all traffic, while nearly all train departures in southern Sweden and parts of Norway were canceled, as the strong winds knocked down trees across the tracks in several places.

The central train station in Sweden's second largest city, Goteborg, was left completely without power, and several ferry lines between Denmark, Norway and Sweden were canceled, officials said.

No injuries were reported, but police in Norway and Sweden urged people to stay indoors.

Power companies said they had called in extra personnel to restore electricity but that the strong winds made it nearly impossible to repair the damaged power lines.

The storm was expected to move eastward during the day, and could possibly reach Finland late Sunday, the Swedish Meteorological and Hydrological Institute said.
