The 2020–2021 European windstorm season was the sixth instance of seasonal European windstorm naming in Europe. This is the second season in which the Netherlands participates, joining Ireland's and the United Kingdom's meteorological agencies. The new season's storm names were released on 1 September 2020. Storms that occur up until 31 August 2021 will be included in this season. The Portuguese, Spanish, and French meteorological agencies will again collaborate too, joined by the Belgian meteorological agency. Background and naming In 2015, the Met Office and Met Éireann announced a pilot project to name storm warnings as part of the "Name our Storms" project for wind storms and asked the public for suggestions. The meteorological offices produced a full list of names for 2015–2016 through to 2017–2018, common to both the United Kingdom and Ireland, with the Netherlands taking part from 2019 onwards. Names in the United Kingdom will be based on the National Severe Weather Warning Service, when a storm is assessed to have the potential for an Amber ('be prepared') or Red ('take action (danger to life)') warning. There are two main naming lists: one created by the national meteorological agencies of the United Kingdom, Ireland, and the Netherlands, and another created by the equivalent agencies from France, Spain, Portugal, and Belgium. Additionally, former Atlantic hurricanes will retain their names as assigned by the National Hurricane Center of the United States. Also, some of these storms may be of tropical origins. For example, ex-Hurricane Lorenzo of 2019 made landfall in Ireland and the United Kingdom. All details on tropical storms and hurricanes can be found on the National Hurricane Centre. Western group (United Kingdom, Ireland and the Netherlands) The following names have been selected for the 2020–2021 season. South western group (France, Spain, Portugal and Belgium) This will be the fourth year in which the meteorological agencies of France, Spain and Portugal will be naming storms that affect their areas. This naming scheme partially overlaps that used by the United Kingdom, Ireland and the Netherlands, as storms named by the other group of agencies will be used reciprocally.
