The St Jude storm, also known as Cyclone Christian and by other names, was a severe European windstorm that hit Northwestern Europe on 27 and 28 October 2013 causing at least 17 deaths. Winds of up to 80–90 mph (130–145 km/h) were forecast for southern England, but the highest windspeed was in Denmark, where a gust of 120.8 mph (194.4 km/h) was recorded in the south of the country on the afternoon of 28 October, the strongest wind recorded in the country's history.
Although it was reported that the storm was named by a clerk at the UK's Met Office, the Met Office themselves have stated that they do not know who named the storm. The storm was named by the Weather Channel UK meteorologist Leon Brown, after the feast of Saint Jude the Apostle, which takes place on 28 October, the day when the storm was expected to be at its height. The name is reported to have been popularised on Twitter before being adopted by the media in the United Kingdom.
The storm was named “Christian” on 26 October 2013 by the Free University of Berlin's meteorological institute. According to The Guardian, European Union institutions are officially referring to the storm as “Christian”.
The Swedish Meteorological and Hydrological Institute named the storm “Simone”, based on the Swedish name day list. The European Windstorm Centre, a UK-based forecaster, gave the storm the name “Carmen”.
