Ferries were canceled, flights were delays, roads and streets were flooded, trees were uprooted, people were injured by falling branches and thousands remained without electricity Tuesday.

In Oslo, officials urged people to work from home Tuesday. On its website, the Norwegian Water Resources and Energy Directorate warned of “extremely heavy rainfall” in southern Norway, adding “unnecessary traffic should be avoided.”

“This is a very serious situation that can lead to extensive consequences and damages. There will be extensive flooding, erosion damage and flood damages to buildings and infrastructure,” it said in English on its website.

In Finland, authorities urged people to rethink whether it “it is necessary to go out” to sea, Ville Hukka, a spokesperson for the Gulf of Finland Coast Guard District was quoted as saying by Finnish newspaper Hufvudstadsbladet.

Floods and slides closed dozens of roads in southern Norway and neighboring Sweden and dozens of people have been evacuated following the storm. There were scattered reports of helicopters being used to fly people out of affected areas. Denmark’s Meteorological Institute, meanwhile, reported of waves of up to eight meters (26 feet) and beach houses were seen washed into the North Sea.

On Monday, a 50-year old woman was killed in Lithuania by falling trees near the Latvian border. In central Sweden, a train was partly derailed because the embankment under the rails had been washed away. Three were people were slightly injured.

Also Monday in Latvia, near the Belarus border, a second person died on Monday when a tree fell on him, Latvian television said, adding he died of his injuries. The man was not further identified.

Norwegian authorities kept the extreme weather warning alert at its highest level in southern Norway due to heavy rain, mudslides and flash floods. They also sent out text messages in several foreign languages, including English, to holidaymakers warning of the foul weather.

In the Swedish town Are, a ski resort, roads and streets were flooded. The Susaback river that runs through Are, some 533 kilometers (331 miles) from Stockholm, went over its banks and flooded much of downtown. Authorities urged people to stay indoors.
