2021–22 European windstorm season

The 2021–22 European windstorm season was the seventh instance of seasonal European windstorm naming in Europe. This was the third season in which the Netherlands participated, alongside the meteorological agencies of Ireland and the United Kingdom (Western group). The season's storm names were released on 1 September 2021. Storms that occurred up until 31 August 2022 were included in this season. The Portuguese, Spanish, French and Belgian meteorological agencies collaborated again, for the fifth time, joined by the Luxembourg meteorological agency (South-western group). This was the first season when 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
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 multiple regional naming lists: one created by the national meteorological agencies of the United Kingdom, Ireland, and the Netherlands, another created by the equivalent agencies from France, Spain, Portugal, Belgium and Luxembourg. This season saw the addition of two groups in southern and south eastern Europe, grouped along the Mediterranean. As in previous years, former Atlantic hurricanes retained their names as assigned by the National Hurricane Center of the United States.

From the autumn of 2021, the names issued by other meteorological services were included on the charts of the Berlin Wetterkarte and Free University of Berlin using the prefix "int." under the EUMETNET umbrella.

Western Group (United Kingdom, Ireland and the Netherlands)
The following names were chosen for the 2021–2022 season in the United Kingdom, Ireland, and the Netherlands.

South-western Group (France, Spain, Portugal, Belgium and Luxembourg)
This was the fifth year in which the meteorological agencies of France, Spain and Portugal named storms that affected their areas. The naming scheme partially overlapped that used by the United Kingdom, Ireland and the Netherlands, as storms named by the other group of agencies were used reciprocally.

Eastern Mediterranean Group (Greece, Israel and Cyprus)
This was the first year in which the meteorological agencies of Greece, Israel and Cyprus named storms that affected their areas. The naming scheme partially overlapped that used by the France, Spain, Portugal, Belgium and Luxembourg, as storms named by the other group of agencies were used reciprocally.

Central Mediterranean Group (Italy, Slovenia, Croatia, Montenegro, North Macedonia and Malta)
This was the first year in which the meteorological agencies of Italy, Slovenia, Croatia, Montenegro, North Macedonia and Malta named storms or former cyclones that affected their areas. Storms or cyclones named by the other group of agencies were used reciprocally.

Northern Group (Iceland, Denmark, Norway, Finland and Sweden)
The naming strategy for the Northern group (Iceland, Denmark, Norway, Finland and Sweden) is slightly different than the other groups, as names are not announced beforehand to prevent the names being used before a storm formally qualifies. Storms or former cyclones named by the other group of agencies were used reciprocally, unless the names used in other groups were not pronounceable in the local language. However, if a Northern group storm was used to overwrite another storm like Eunice, it was not added to the overall total of storms within the 2021–22 European windstorm season, as they were the same storms with different names. This was the case for storm Eunice, which was named Nora in Denmark (and so the latter name is not listed below).

All storms named by meteorological organisation in Europe from their respected forecasting areas. As well as Atlantic hurricanes and storms that transitioned into a European windstorm and retained its name as assigned by the National Hurricane Center in Miami, Florida:

Storm Athina (Christian)
A depression formed on 4 October in the western Mediterranean and was named Christian by the Free University of Berlin. It was named Storm Athina by Hellenic National Meteorological Service on 6 October and intensified when it arrived in southern Italy on 8 October. The system then passed into the Ionian Sea before dissipating on the 9th.

In central Italy, Athina caused record rainfall in Liguria with 496 mm in Savona in just 6 hours, breaking the record of 472 mm in November 2011. The main roads of the island of Corfu turned into rivers, the basements were flooded, power outages occurred, small landslides occurred and firefighter interventions were required with the storm front rains preceding the system.

Storm Ballos
Storm Ballos was named by Hellenic National Meteorological Service on 13 October, heavy rain and floods in Athens on October 15 and some of the islands have been reported. Heavy rain was predicted for 15 October in Eastern Macedonia and Thrace and a red alert with heavy rain and severe thunderstorms in North Aegean islands (meteoalarm).

Storm Aurore (Hendrik)
A storm, named Hendrik by the Free University of Berlin on 16 October, developed over the northern Atlantic Ocean. Another developing low south of Ireland was called Aurore by Meteo France on 20 October. Passing over the south of England the following night, Aurore generated very strong south-westerly winds and heavy rains from Brittany to the Grand Est in France, then central Europe as it merged with Hendrik over western Europe. An orange alert for wind was issued by meteorological services in western Europe, and even red for parts of southern and eastern Germany. The system reached northern Russia on 22 October and dissipated in northern Siberia the next day.

Aurore/Hendrik brought widespread gusts of 100 to 120 km/h from northern France to eastern Germany and beyond, reaching speeds of 175 km/h in Fécamp in Normandy. Fallen trees disrupted train service in several countries. Two tornadoes touched down in the Netherlands, in Brittany (France), three possible tornadoes were reported in Plozévet, Riec-sur-Belon and Kernascléden. and in Germany, another tornado touched down near Kiel.

Four people were killed in Poland. One death was reported in Germany. and another in the United Kingdom. Around 250,000 clients lost electricity in France and 275,000 in the Czech Republic.

Cyclone Apollo
Cyclone Apollo was a Mediterranean tropical-like cyclone that affected many countries on the Mediterranean coast, especially Italy and Libya. The storm killed at least 5 people and left 2 others missing due to flooding from the cyclone, in the countries of Tunisia, Algeria, Malta, and Italy, where the worst of the effects have been felt, especially on the island of Sicily. Around 22 October 2021, an area of organized thunderstorms formed near the Balearic Islands, with the disturbance becoming more organized and developing an area of low pressure around 24 October. On the next day, the low started to develop a low-level circulation center, and moved into the Tyrrhenian Sea. On 28 October, the system organized even further and intensified, which prompted forecast offices in Europe to name the low. Italy's Servizio Meteorologico named the storm Apollo (which was then adopted by the Free University of Berlin). On 29 October 2021, a ship in the Mediterranean Sea passed through Apollo and measured a peak wind speed of 104 km/h and a pressure of 999.4 hPa, indicating that Apollo is still strengthening. After Apollo made its closest approach to Sicily during the overnight hours of October 29, Apollo appeared to have begun to weaken as its convection waned and its low-level circulation became exposed on visible satellite imagery on 30 October 2021, on 31 October 2021, Apollo made landfall near Bayda and stayed inland until emerging over the Mediterranean a few hours later. Then, on 2 November, it dissipated off the coast of Turkey.

Heavy rain from the cyclone and its precursor caused heavy rainfall and flooding in Tunisia, Algeria, Southern Italy, and Malta, killing 5 people and leaving 2 other people missing. The flooding was especially severe in the provinces of Catania and Siracusa, in Eastern Sicily.

Storm Blas
On November 5, the Spanish Meteorological Agency (AEMET) started tracking a low near the Balearic Islands and named it Blas. An orange alert was issued for these islands, for coastal phenomena and rain. The north of Catalonia was declared an Orange Zone, as strong winds blew inland from the Spanish Navarre and Aragon. Météo-France has also issued a yellow alert for Aude and Pyrénées-Orientales for wind, as well as Corsica for rain.

As the system stalled between Sardinia and the Balearic Islands on November 8, AEMET predicted a strengthening for the next two days and maintained its alerts. At 00:00 UTC on 11 November, the system was again very close to the Balearic Islands. After striking the islands again, the storm then slowly weakened while drifting back towards the southeast. On 14 November, the cyclone turned northward, moving over Sardinia and Corsica, before curving back southwest on 15 November and moving over Sardinia again, while strengthening in the process. On 16 November, Blas turned eastward once again, passing just south of Sardinia and moving towards Italy, before dissipating over the Tyrrhenian Sea on 18 November.

On November 6, gusts of 75 km/h were recorded at Es Mercadal and 95 km/h at the lighthouse of Capdepera in the Balearic Islands where waves of 8 m hit the coast. Menorca was cut off from the world after the closure of the ports of Mahón and Ciutadella. On November 9 and 10, Blas again brought high winds and heavy rain to the Balearic Islands, causing at least 36 incidents, mostly flooding, landslides and blackouts. A crew member had to be rescued after his sailboat's mast broke, leaving the boat adrift 80 km west of Soller.

On November 6, a waterspout was reported in Melilla, a Spanish enclave on the coast of Morocco. In France, gusts of 140 km/h were noted on November 7 at Cap Béar, as well as 111 km/h in Leucate and 100 km/h in Lézignan-Corbières.

The storm caused severe weather on the Algerian coast with exceptional rainfall. On November 9, a building collapsed in Algiers following torrential rains on the city, causing the deaths of three people. On November 11, the heavy rain continuing on Algiers caused another landslide on houses in the Raïs Hamidou neighborhood, causing the deaths of three other persons.

From November 8 to 11, convective bands associated with the storm caused 3 deaths in Sicily.

Storm Arwen
Storm Arwen was named by the Met Office on 25 November 2021. Red warnings for wind were issued for north-eastern parts of the UK, as well as extensive amber and yellow warnings for much of Scotland, Northern Ireland, Wales and most of England. Dangerous waves were also forecasted causing disruption to ferry services. At 17:00 UTC on 26 November, Network Rail closed the rail lines north of Berwick-upon-Tweed and LNER stopped running trains north of Newcastle. More than 120 lorries were stuck in heavy snow on the M62 in Greater Manchester, with the motorway shut by police while ploughs and gritters led the rescue effort. The storm closed the entire Tyne and Wear Metro network which said in statement "this is the worst winter storm to hit metro in 41 years of operations".

Dozens of crashes were reported by police agencies across the UK, many roads were closed due to fallen trees, snow or ice, and more than 130,000 homes were without power on a cold night in the north.

A man in the Northern Irish town of Antrim died when a falling tree hit his car. Another man was hit and killed by a falling tree in Cumbria and a third man died after his pick-up truck was struck by a falling tree in Aberdeenshire.

The storm caused damage to the Lithuanian coast as well, with local authorities calling it the "worst storm since Cyclone Anatol in 1999". The storm reached winds of 93 km/h with gusts of 125 km/h. The storm did not cause any fatalities, but considerably damaged infrastructure and protective dunes along the Curonian Spit.

Storm Corrie
Storm Corrie was named on 29 January 2022 by the Met Office. Storm Corrie prompted Amber wind warnings to be issued for the northeast of Scotland. A peak gust of 93 mph was recorded on the east coast of Scotland. A wider yellow warning was issued for most of the east coast of England down to the north coast of Norfolk.

In the Netherlands, the combination of Storm Corrie and a high tide forecast in the North Sea led to the decision to close the Oosterscheldekering.
