Cyclone Xaver (DMI: Bodil, SMHI: Sven) also known as the North Sea flood or tidal surge of 2013, was a winter storm that affected northern Europe. Force 12 winds and heavy snowfall were predicted along the storm's path, and there were warnings of a significant risk of storm surge leading to coastal flooding along the coasts of the North and Irish Seas.
The Free University of Berlin gave the storm the name Xaver (a German form of the name Xavier), which had been previously given to the Berit storm of 2011. The Danish Meteorological Institute following a decision that the institute would name storms affecting Denmark following the St. Jude storm (which had retroactively been given the name Allan) named the storm Bodil. In Poland, the storm is named Ksawery, which is the Polish equivalent of Xaver. The Swedish Meteorological Institute gave the storm the name Sven, after the name day of 5 December. In the Netherlands the storm was known as the "Sinterklaasstorm", as 5 December is traditionally celebrated as St. Nicholas Eve in the country. Twitter users in the UK were using the hashtags #scotstorm, #Xaver and #UKstorm. The European Windstorm Centre, a UK-based forecaster, gave the storm the name Cameron.
Xaver formed to the south of Greenland on 4 December, and explosively deepened as it moved east to pass the north of Scotland on 5 December. Over the next few days Xaver moved over Southern Norway and Sweden intensifying further, reaching its lowest pressure over the Baltic Sea.
The low pressure system formed on 4 December off the west coast of Iceland and is expected to deepen explosively overnight. The UK Met Office issued an amber warning over Scotland and northern parts of England, where wind gusts may reach 90 miles per hour (145 km/h). On 4 December the Environment Agency released a warning to communities along the East Coast of England to prepare for the most serious tidal surge in 30 years, with a significant threat of coastal flooding between 5–7 December.
