2019–20 European windstorm season
The 2019–20 European windstorm season is the fifth instance of seasonal European windstorm naming in Europe. This will be the first season in which the Netherlands will participate, joining the United Kingdom and Ireland'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. The Portuguese, Spanish and French meteorological agencies will again collaborate too, joined by the Belgian meteorological agency.

Background and namingEdit
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 2015–16 through to 2017–18, 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, created by the national meteorological agencies of the United Kingdom and Ireland, and France, Spain and Portugal respectively. Additionally, former Atlantic hurricanes will retain their names as assigned by the National Hurricane Center of the United States.
Besides these naming systems, the Free University of Berlin also names high and low pressure areas through its "Adopt a vortex" programme. The Nordic nations of Denmark, Norway and Sweden also name storms with more limited reciprocation. Other nations may also name storms either through their national meteorological institutions or popularly.
United Kingdom, Republic of Ireland and NetherlandsEdit
'Liam' was chosen through a poll made by Met Éireann on Twitter.
France, Spain, Portugal and BelgiumEdit
This will be the third year in which the meteorological agencies of France, Spain and Portugal will be naming storms which affect their areas. This naming scheme is partially overlapping with that used by the United Kingdom, Ireland and the Netherlands, as storms named by the other group of agencies will be used reciprocally.
The following names have been selected for the 2019–2020 season:
The first designated system of the season was Storm Lorenzo, when Met Éireann issued yellow wind warnings for Ireland and an orange warning for the western coastal counties. The storm consisted out of the remnants of Hurricane Lorenzo, which had turned extratropical.

|Area affected||Azores, Ireland, United Kingdom|
|Date of impact||2 October-4 October|
|Maximum wind gust||101 mph (163 km/h) Corvo Island, Azores|
|Lowest pressure||966 mbar (28.5 inHg)|
On 26 September 2019, the Portuguese meteorological agency (IPMA) began issueing advisories for Hurricane Lorenzo. The National Hurricane Center issued hurricane and tropical storm watches on 30 September 2019 for the Azores, which were later upgraded to warnings.
The same day, Met Éireann issued a yellow warning for wind for the entirety of Ireland, as well as an orange warning for the western coastal counties. The Met Office issued yellow wind warnings for Northern Ireland, Cornwall and parts of Devon and south-west Wales. Upon issueance of the orange warning, Met Éireann named the extratropical remnants of Lorenzo "Storm Lorenzo".[note 1] Storm Lorenzo dissipated above the Irish Sea on 4 October.
On 3 October, the M6 Buoy, located about 400 km (250 mi) west of Mace Head, Galway, recorded a pressure of 969 mbar (28.6 inHg) near Lorenzo's centre. The same buoy also recorded a maximum wave height of 12.5 m (41 ft). On the day of the storm passing Ireland, 4 October, new weather warnings were issued for the counties Longford, Westmeath, Galway, Mayo, Roscommon and Clare. The highest recorded wind gust was 66 mph (107 km/h), with the highest 10-minute mean being 54 mph (87 km/h), both recorded at Mace Head.
Power was cut to almost 20,000 homes in Ireland at the height of the storm, with floodings occurring throughout the country. River Eske partially flooded Donegal as result of nearly 50 mm (2.0 in) of rain falling as high tide was approaching. The amount of damage country-wide, however, was less than anticipated for.
