2019–20 European windstorm season
The 2019–20 European windstorm season was the fifth instance of seasonal European windstorm naming in Europe. This is the first 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 6 September 2019. In July 2019, it was announced that storm seasons would run from 1 September 2019 to 1 September 2020.[1][2] The Portuguese, Spanish and French meteorological agencies again collaborated too, joined by the Belgian meteorological agency.

Other systems[edit]
On 29 September, a moderate storm named Mortimer by FUB moved across central Europe and killed three people.[214]
In late October 2019, a medicane formed far east in the Mediterranean Sea. It affected Cyprus, Israel and Egypt. The storm formed in the far east of the sea, something which is not seen often.[215]
On 10–11 December, an explosively deepening storm affected Iceland, where the meteorological office declared its first red warning for parts of the country.[216] The system was named Siro by the Free University of Berlin. The storm dropped to a pressure of 949 mbar (28.0 inHg), bringing strong winds and blizzard conditions, causing a complete halt to transportation and power loss to 20,000. The storm was described by Icelandic meteorologists as a once in a decade event.[217]
On 15 January the extreme weather event Didrik hit the southern coast of Norway with high coastal waters. This weather event was caused by Storm Brendan, which for a longer period had stalled south east of Iceland, and a secondary low named Gerlinde by the Free University of Berlin. Storm Brendan had for a longer period pushed water towards the coast of Norway bringing high coastal waters already from 13 January. Gerlinde was expected to bring even higher water levels. Due to these two low pressure areas, combined with full moon 10 January, the Norwegian Meteorological Institute named the event Didrik. Gerlinde moved quicker than expected over southern Norway and brought lower water levels to the southern coast, but Brendan however moved towards the coast more powerful than expected and brought higher water levels on the western coast. The weather event made damage to many buildings along the coast as well as disrupt railway services due to flooding.[218]
On 28 January, Storm Lolita, named by FUB, caused two deaths in Germany.[219][220]
On 14 February, a rapidly deepening low in the Atlantic affected Iceland, named Uta by the Free University of Berlin. Red wind warnings for the south of Iceland were issued with reports of coastal flooding around the Reykjanes peninsula.[221]
On 22 February storm Tuuli, named by the Finnish Meteorological Institute, hit Finland.
On 27 February Bianca (FUB) affected France, Switzerland and Germany.[222]
On 12 March storm Laura hit Denmark and southern Sweden. It was named Laura by the Danish Meteorological Institute, and known as Hanna by the Free University of Berlin. In Sweden winds gusts of up to 136 km/h (85 mph; 73.5 kn; 37.8 m/s) was recorded. Strong winds cut the power to more than 20,000 people, and also closed the Öresund bridge.[223]
On 25 July a storm hit the eastern parts of Finland. Despite its severity it was only unofficially named Uuno by the Finnish media. Strong winds caused trees to fall over electrical lines cutting power to more than 3,000 people.[224] The damages to forests was estimated to cost between 2 and 3 million euros.[225]
On 30 July another storm hit Finland. This was more powerful and was officially named Päivö by the Finnish Meteorological Institute.
