2022–23 European windstorm season

The 2022–23 European windstorm season was the deadliest and costliest European windstorm season on record, mainly because of the impact in Northern Libya of Storm Daniel, which became the deadliest and costliest medicane ever recorded as well as the deadliest tropical or subtropical system worldwide since 2008.

The 2022–23 season was the eighth instance of the European windstorm naming in Europe, with the season's storm names being announced on 1 September 2022. Storms that occurred up until 31 August 2023 were included in this season, although two systems occurred in September: Storm Daniel was named on 4 September and lasted until 12 September, and Storm Elias existed during the final week of September and overlapped with the first storm of the succeeding season. This was the fourth season where the Netherlands participated, alongside the United Kingdom's Met Office and Ireland's Met Éireann in the western group. The Portuguese, Spanish, French and Belgian meteorological agencies collaborated for the sixth time, joined by Luxembourg's agency (South-western group). This is the second season where Greece, Israel and Cyprus (Eastern Mediterranean group), and Italy, Slovenia, Croatia, Montenegro, North Macedonia and Malta (Central Mediterranean group) named storms which affected their areas.

Background and naming

Definitions and naming conventions

Main article: Weather system naming in Europe

There is no universal definition of what constitutes a windstorm in Europe, nor is there a universally accepted system of naming storms. For example, in the Western Group, consisting of the UK, Ireland, and the Netherlands, a storm is named if one of the meteorological agencies in those countries issues an orange warning (amber in the UK), which generally requires a likelihood of widespread sustained wind speeds greater than 65 km/h, or widespread wind gust speeds over 110 km/h. (Required wind speeds vary slightly by agency and by season.) Both the likelihood of impact and the potential severity of the system are considered when naming a storm. The Southwest Group of Spain, Portugal, and France share a similar storm-naming scheme, though their names differ from those used by the Western Group. In Greece, however, naming criteria were established for storms when the storm's forecasted winds are above 50 km/h over land, with the wind expected to have a significant impact to infrastructures. In Denmark, a windstorm must have an hourly average windspeed of at least 90 km/h (25 m/s).

The Meteorology Department of the Free University of Berlin (FUB) names all high and low pressure systems that affect Europe, though they do not assign names to any actual storms. A windstorm that is associated with one of these pressure systems will at times be recognized by the name assigned to the associated pressure system by the FUB. Named windstorms that have been recognized by a European meteorological agency are described in this article.

Naming conventions used in Europe are generally based on conditions that are forecast, not conditions that have actually occurred, as public awareness and preparedness are often cited as the main purpose of the naming schemes–for example, a reference. Therefore, an assignment of a storm name does not mean that a storm will actually develop.

Western Group (United Kingdom, Ireland and the Netherlands)

In 2015, the Met Office and Met Éireann announced a project to name storms as part of the "Name our Storms" project for windstorms and asked the public for suggestions. The meteorological offices produced a full list of names for 2015–2016 through 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.

The following names were chosen for the 2022–23 season in the United Kingdom, Ireland, and the Netherlands. For a windstorm to be named, the United Kingdom's Met Office, Ireland's Met Eireann, and the Netherlands KNMI have to issue an amber weather warning, preferably for wind, but a storm can also be named for amber warnings of rain and snow (e.g. Storm Arwen in 2021).

It had formerly been a Category 1 hurricane that transitioned into a post-tropical cyclone on 8 September, north of the Azores. It dissipated off the coast of Portugal on 15 September.

Large waves and heavy rainfall hit the Azores. Ex-Danielle brought heavy rain to mainland Portugal while meandering near its coast. Between 12 and 13 September, 644 accidents were reported throughout the country. While many downed trees and flash floods were reported, no fatalities resulted from the downpours. In Manteigas, under a "state of calamity" at the time, following intense summer forest fires in nearby areas of the Serra da Estrela mountain range, floods and landslides caused major damage. Four vehicles were dragged into the Zêzere River. Heavy rain extended to as far north as Braga. Covilhã saw 67.2 millimetres (2.65 in) of rain while Viseu saw 62 millimetres (2.4 in) of rain. Minor wind and flooding damage was reported in both Lisbon and Setúbal. Much of Spain was put on yellow alert as wind, rain and thunderstorms triggered by the cyclone moved inland.

A cold wave impulsed an extratropical cyclone in Europe and the storm interacted of anticyclone in the south in central Atlantic, the storm moved up towards Spain and Portugal, when on 22 October it received the name Beatrice. The system was named Helgard II by the FUB, and Helgard I went on into eastern Europe, as Helgard II did not affect eastern Europe. The storm then went on to bring heavy wind and rain to the Iberian Peninsula. The outer bands of this storm were also related to the supercells in northern France and southern England which produced at least nine tornadoes, including the intense Bihucourt tornado.

A band of intense thunderstorms on the northern leading edge of Beatrice crossed southern and eastern England during the afternoon and evening of 23 October, where a yellow weather warning for thunderstorms was issued. Heavy rainfall and strong winds were reported widely, resulting in some flooding and structural damage, and flights were disrupted at Heathrow Airport for several hours.

Maximum wind gust	185 km/h (115 mph)
Lowest pressure	994 hPa (29.35 inHg)
Fatalities	1 (indirect)

Storm Cláudio was named on 31 October 2022. An orange alert for strong winds was put in place for four departments in northwest France. The Met Office issued a yellow weather warning for wind for most of the south coast of England, stretching from Weymouth to Kent. The Met Office had forecast gusts of 50–60 mph (80–97 km/h) with isolated gusts of >70 mph (110 km/h) on exposed coasts. The highest gust of 115 miles per hour (185 km/h) was recorded at The Needles on the Isle of Wight, with a 1-minute sustained wind recorded as high as 105 mph (169 km/h). A trampoline that was caught underneath a train meant that no trains could run from Worthing to Hove for more than three hours. High winds caused part of the southwest corner of the West Pier in Brighton to collapse into the sea. Two giant silver baubles were blown down by the storm and rolled down Tottenham Court Road in London. However, no damage or injuries was reported.

Storm Cláudio hit the UK as a deepening low pressure system, the lowest onshore pressure of 994 hPa (29.35 inHg) was recorded in Plymouth at 22:00 on 31 October. The centre of the shortwave made landfall in Southern Wales, near Cardiff, at around midnight – with the storm further north than had initially been forecasted by both the Met Office and Météo-France. In the wake of Storm Cláudio heavy convective showers produced flash flooding and lightning across the Southwest of England on 1–2 November. At 13:23 on 1 November, a thunderstorm brought winds as strong as 84 mph (135 km/h) to exposed parts of Cornwall. In Devon, fire crews were called to a pre-school in Willand, Devon after a suspected lightning strike lead to a small fire at 14:40. Between the evening of the 31 October to the evening of the 2 November, more than 11,000 lightning strikes had been registered across the British Isles, with the majority of activity centred over the Channel Coasts.

Track of Storm Efrain according to the University of Berlin
Area affected	Portugal, France
Date of impact	10 December 2022 – 17 December 2022
Lowest pressure	955 hPa (28.20 inHg)
Fatalities	3 (Indirect)
Power outages	None
Damage	Unspecified

Storm Efraín was named on 10 December 2022. Crossing the cold waters heading towards the Azores and the Iberian Peninsula, a powerful anticyclone blocking its path to higher latitudes, the storm quickly intensified thanks to the presence of an atmospheric river of subtropical origin associated with its southern flank. The storm hit the Iberian Peninsula and France from 13 to 16 December before dissipating.

Efraín brought strong winds, heavy rains and rough seas to the Azores. Flooding due to heavy rains affected the provinces of Extremadura and Castilla-La Mancha in Spain. Strong gusts and rain caused landslides on the famous Caminito del Rey in Andalusia. Several stations in Madrid have been forced to close due to flooding. An environmental officer drowned during a flood in Villarino de los Aires (Salamanca).

In Portugal, Efraín caused flooding in the Tagus River basin. According to the Portuguese Civil Protection Agency, a government body, some 5,000 rescue workers were on duty across the country and authorities estimated the damage at millions of euros.

In France, the freezing rain and snow associated with the warm front of the system disrupted transport. Two accidents in Saône-et-Loire caused the death of a motorist on the A39 motorway and two truck drivers on a secondary road. The Minister of Transport, Clément Beaune, announced the cancellation of part of the flights from Orly and Roissy-Charles-de-Gaulle airports. In Lyon, all the buses remained stationary for part of a morning to avoid accidents.

Storm Fien (Harto)

Storm Fien
Area affected	Spain, France, Italy & Central Europe.
Date of impact	14–20 January 2023
Maximum wind gust	150 km/h (93 mph) (Pyrenees)
Lowest pressure	Unspecified
Fatalities	1

On 14 January 2023, the Spanish State Meteorological Agency (AEMet) assigned the name Fien to the depression then located on Newfoundland. It was moving towards the south of the British Isles. It reached the Bay of Biscay on 17 January. Then crossing into the Mediterranean, it passed over northern Italy on the 18th and turned northward to end up in the Baltic countries the following day. At 0:00 UTC on 20 January, Fien reached northwestern Russia.

Consequently, Orange marine weather warnings for high winds were issued by AEMET for 15 January for north-western Galicia province, with yellow marine wind warnings stretching all the way to the border with France in Basque.

In France, the southwest was affected during the night of 16 to 17 January. Winds of up to 150 km/h (93 mph) were recorded in the Pyrenees, toppling trees and cutting off electricity to 15,000 customers in Nouvelle-Aquitaine and Occitania but without major damage or casualties. According to Météo-France, 30 to 40 mm (1.2 to 1.6 in) of rain fell in the Landes and Pyrénées-Atlantiques, and up to 55 mm (2.2 in) in Tarbes, while above a certain altitude the rain changed to snow. The rain caused flooding in places. Snow in Auvergne-Rhône-Alpes, Haute-Savoie and the Massif Central caused difficulties on the roads and forced the closure of schools. In Corsica, a landslide disrupted trains between Ajaccio and Bastia and ferries were canceled by Corsica Linea.

In Spain, almost the entire country has been put on high alert for high winds, heavy rain and snow, depending on altitude, as well as rough seas. In the north, rivers approached overflow level. An 80-year-old man who disappeared during the storm has been found dead in the port of the Basque town of Bermeo. In Sondika, emergency services rescued a bus full of children stuck on a flooded road. Winds of up to 90 km/h (56 mph) in Barcelona caused damage. After its passage, arctic air gave way to very cold temperatures.
