Stormy weather in northern Europe on January 4-5 has led to localised surge flooding primarily along the Baltic Sea coastlines of Germany, Poland and Denmark. Tide gauges recorded water levels up to 1.83m (6.0 ft) above normal, inundating coastal areas of several cities and towns. Water levels have since receded. In Germany, areas affected include Hamburg, Lübeck, Wismar, Kiel, Rostock, Warnemünde, Flensburg, Eckernförde and the islands of Rügen and Usedom. Media reports indicate that around 30 commercial and residential properties have been inundated with floodwater in Flensburg, Germany. There are reports of flooding in parts of Lübeck's World Heritage-listed medieval town. A number of buildings in Hamburg’s dockland area were impacted and there are reports of minor damage to the port. Local authorities reported that most residents had heeded warnings and protected their properties with sand bags . In the coming days, the Ministry of the Environment is expected to conduct assessments of cities and towns along Germany’s Baltic Sea coastline to determine the extent of the damage. According to Germany’s Federal Office for Maritime and Hydrography (BSH), the surge was the largest in the Baltic Sea since 2006. In Poland, there were reports of flooding in Nowy Dwor Gdanski, and in Denmark, the areas of Amager and Dragør in Copenhagen were worst affected. Officials confirmed there are no reports of fatalities or injuries.
