Storm tides of the North Sea are coastal floods associated with extratropical cyclones crossing over the North Sea, the severity of which is affected by the shallowness of the sea and the orientation of the shoreline relative to the storm's path, as well as the timing of tides. The water level can rise to more than 5 metres (17 ft) above the normal tide as a result of storm tides.
The 1953 North Sea flood was a major flood caused by a heavy storm surge that struck the Netherlands, north-west Belgium, England and Scotland. Most sea defences facing the surge were overwhelmed, resulting in extensive flooding.
The North Sea flood of 1962 was a natural disaster affecting mainly the coastal regions of West Germany and in particular the city of Hamburg in the night from 16 February to 17 February 1962. In total, the homes of about 60,000 people were destroyed, and the death toll amounted to 315 in Hamburg. The extratropical cyclone responsible for the flooding had previously crossed the United Kingdom as the Great Sheffield Gale, devastating the city of Sheffield and killing nine people.
Cyclone Tilo was a European windstorm which affected northern and western Europe in early November 2007. Combining with the remnants of Hurricane Noel, Tilo's storm surge led to the North Sea flood of 2007, affecting the coastlines of the Netherlands, the United Kingdom, Germany, Denmark, Norway and Belgium, starting on the night of 8–9 November 2007.
European windstorms are powerful extratropical cyclones which form as cyclonic windstorms associated with areas of low atmospheric pressure. They can occur throughout the year, but are most frequent between October and March, with peak intensity in the winter months. Deep areas of low pressure are common over the North Atlantic, and occasionally start as nor'easters off the New England coast. They frequently track across the North Atlantic Ocean towards the north of Scotland and into the Norwegian Sea, which generally minimizes the impact to inland areas; however, if the track is further south, it may cause adverse weather conditions across Central Europe, Northern Europe and especially Western Europe. The countries most commonly affected include the United Kingdom, Ireland, the Netherlands, Norway, Germany, the Faroe Islands and Iceland.
Cyclone Xynthia was an exceptionally violent European windstorm which crossed Western Europe between 27 February and 1 March 2010. It reached a minimum pressure of 967 mb (28.6 inHg) on 27 February. In France—where it was described by the civil defence as the most violent since Lothar and Martin in December 1999—at least 51 people were killed, with 12 more said to be missing. A further six people were killed in Germany, three in Spain, one in Portugal, one in Belgium and another one in England. Most of the deaths in France occurred when a powerful storm surge topped by battering waves up to 7.5 m (25 ft) high, hitting at high tide, smashed through the sea wall off the coastal town of L'Aiguillon-sur-Mer. A mobile home park built close to the sea wall was particularly hard-hit. The sea wall was about two hundred years old, built in the time of Napoleon; critics said that situating a mobile home park so close to the sea wall showed poor coastal development practices. The storm cut power to over a million homes in France and a million customers in Portugal lost power.
Cyclone Carmen was an extratropical cyclone and European windstorm which crossed the Atlantic Ocean and affected the United Kingdom, Ireland, France, Belgium, and the Netherlands in November 2010.
The December 1981 windstorm was a severe storm that particularly affected southern England, Wales and south west France during 13 December 1981. The storm formed as a secondary low.
Cyclone Berit was a very strong European windstorm that formed as a tropical wave near the Lesser Antilles in mid-November 2011. The storm began producing heavy rain and snow over Northern Europe on 24 and 25 November. Scotland saw its first snowfall since March, earlier in the year. The Faroe Islands also reported winds up to 198 km/h and excessive damage. On 25 November, the Norwegian Weather Service named the storm 'Berit'. Another storm, called Yoda, hit Scotland just a day after Xaver. The storm Yoda was widely known as Lille-Berit (Little-Berit) in Scandinavia, as the Norwegian Weather Service did not issue it with an official name.
Hurricane Bawbag, also known as Cyclone Friedhelm was an intense extratropical cyclone which brought hurricane-force winds to Scotland at the beginning of December 2011. The storm also brought prolonged gales and rough seas to the rest of the British Isles, as well as parts of Scandinavia. On 8 December, winds reached up to 165 mph (266 km/h) at elevated areas, with sustained wind speeds of up to 80 mph (130 km/h) reported across populous areas. The winds uprooted trees and resulted in the closure of many roads, bridges, schools and businesses. Overall, the storm was the worst to affect Scotland in 10 years, though a stronger storm occurred less than a month afterwards, on 3 January 2012. Although the follow-up storm was more intense, the winter of 2011–12 is usually remembered for Bawbag among Scots.
Cyclone Ulli was an intense European windstorm. Forming on December 31, 2011 off the coast of New Jersey, Ulli began a rapid strengthening phase on January 2 as it sped across the Atlantic. Ulli was the costliest disaster in January 2012 globally. The damage from the storm in Glasgow was also compared to a storm in 1968.
Cyclone Andrea was an intense European windstorm that affected western and central Europe in early January 2012.
The Gale of January 1976, widely known as the "Capella" storm in Germany and the Ruisbroek flood in Belgium, was one in a series of extratropical cyclones and storm surges, which occurred over January 1976. The gale of 2–5 January 1976 resulted in severe wind damage across western and central Europe and coastal flooding around the southern North Sea coasts. At the time, this was the most severe storm of the century over the British Isles. Total fatalities reached 82 across Europe, although a figure of 100 is given by the World Meteorological Organization. Of these 24 were reported in Britain and 4 in Ireland. Overall losses of US$1.3 billion were incurred, with insured losses standing at US$500 million (1976).
The North Sea flood of 1978 was a storm surge which occurred over 11–12 January causing extensive coastal flooding and considerable damage on the east coast of England between the Humber and Kent. Higher water levels were reached than during the devastating North Sea flood of 1953 from North Shields to King's Lynn, but values were lower towards the Thames. Locally severe flooding occurred in Lincolnshire, The Wash, north Norfolk and Kent. Improvements in flood protection following the devastating flood of 1953 meant that the catastrophic losses seen during that storm were not repeated. The storm caused severe damage to many piers along the east coast of England.
Cyclone Dirk was a large and deep European windstorm that affected Western Europe from the Iberian Peninsula to Iceland from 22 December 2013.
Cyclone Anne was a European windstorm which caused €75 million in damage across western Europe in early January 2014, followed days later by Cyclone Christina.
2013–2014 Atlantic winter storms in Europe were a series of winter storms affecting areas of Atlantic Europe and beyond. The French Atlantic coastal regions, South West and Southern England, West Wales, Ireland, Spanish Atlantic coastal regions were especially affected by a "conveyor belt" series of high-precipitation storms and by high tides. Many storms were explosively deepened by a strong jet stream, many deepening below 950 hPa. The repeated formation of large deep lows over the Atlantic brought storm surges and large waves which coincided with some of the highest astronomical tides of the year and caused coastal damage. The low pressure areas brought heavy rainfalls which led to flooding, which became most severe over parts of England such as at the Somerset Levels. The repeated storms fit into a pattern of disturbed weather in the Northern Hemisphere, which saw from November 2013 a disturbance to the jet stream in the western Pacific, which propagated eastwards bringing a warm winter to Alaska, drought to California, and repeated cold air outbreaks to the eastern USA where the early 2014 North American cold wave resulted.
The 2015–16 UK and Ireland windstorm season was the first instance of the United Kingdom's Met Office and Ireland's Met Éireann naming extratropical cyclones. The season started on 10 November with the naming of Storm Abigail and ended on 28 March with the dissipation of Storm Katie. With a total of eleven named storms, the 2015–16 season is the most active to date.
Storm Darwin a European windstorm that hit Western Europe, particularly Ireland and the United Kingdom on 12 February 2014. The storm brought hurricane-force winds to Ireland the with the Met Office and Met Éireann describing the storm as one of the most significant to affect Ireland, Wales and West England in recent decades. Tini was one of the strongest storms of the 2013–2014 Atlantic winter storms in Europe, and also brought heavy across the UK and Ireland exacerbating the 2013–2014 United Kingdom winter floods, and may have been the most damaging storm of the period.
Storm Dennis was a European windstorm which, in February 2020, became one of the most intense extratropical cyclones ever recorded, reaching a minimum central pressure of 920 millibars. The thirteenth named storm of the 2019–20 European windstorm season, Dennis affected the Republic of Ireland and the United Kingdom less than a week after Storm Ciara, exacerbating the impacts from that storm amidst ongoing flooding in the latter country.
