Since 12 July 2021, several European countries have been affected by catastrophic floods, causing deaths and widespread damage. The floods have affected several river basins, first in the United Kingdom and later across northern and central Europe including Austria, Belgium, Croatia, Germany, Luxembourg, the Netherlands, Switzerland and Italy.At least 217 people have died in the floods, including 177 in Germany, 37 in Belgium, 1 in Italy, 1 in Austria, and 1 in Romania.
Belgian Minister of Home Affairs Annelies Verlinden described the events as "one of the greatest natural disasters our country has ever known." German minister-president Malu Dreyer of the Rhineland-Palatinate state called the floods "devastating". In addition to the confirmed fatalities, the flooding led to widespread power outages, forced evacuations and damage to infrastructure and agriculture in the affected areas. The damage to infrastructure was especially severe in Belgium and Germany.The floods are estimated to have cost up to €2.55 billion (US$3 billion) in insured losses, with the total damage costs being much higher. In the aftermath, scientists, activists and reporters all highlighted the connection to global trends in extreme weather, especially more frequent heavy rainfall caused by climate change.
Between 12 and 15 July 2021, heavy rain fell across the United Kingdom, western Germany, and neighbouring Netherlands, Belgium, and Luxembourg. A storm complex moved east from France into Germany and stalled over the region for two days. Precipitation was intense in the East of Belgium, with 271.5 millimetres (10.69 in) of rain over 48 hours in Jalhay and 217 millimetres (8.5 in) over 48 hours in Spa. Heavy rainfall was also seen in the south of North Rhine-Westphalia and north of Rhineland-Palatinate in Germany where accumulations averaged 100 to 150 mm (3.9 to 5.9 in) in 24 hours, equivalent to more than a month's worth of rain. In Reifferscheid, 207 mm (8.1 in) fell within a nine-hour period while Cologne observed 154 mm (6.1 in) in 24 hours. Some of the affected regions may not have seen rainfall of this magnitude in the last 1,000 years. Floods started in Belgium, Germany, the Netherlands, and Switzerland on 14 July 2021 after record rainfall across western Europe caused multiple rivers to burst their banks.
The European Flood Awareness System (EFAS) issued alerts of life-threatening floods in advance, which were delivered to national authorities.
In the evening of 24 July, heavy thunderstorms caused further flooding, this time in more central northern and southern areas of Belgium, and also in the south of The Netherlands.[ citation needed ]
On 17 July, a flash flood swept through Hallein, a town close to the German border.Rescue workers in the states of Salzburg and Tyrol were placed on high alert for flooding, and Chancellor Sebastian Kurz tweeted "heavy rains and storms are unfortunately causing severe damage in several places in Austria." A man died in Saalbach-Hinterglemm during the floods.
On 15 July, all residents of the city of Liège with a population of approximately 200,000 were urged to evacuate amidst fears that the Meuse river was on the verge of bursting its banks and that a dam bridge could collapse.No vehicles were allowed into the city centre of Liège; traffic was only allowed to leave as part of the evacuation. By 16 July, several smaller municipalities in Limburg Province were also given the order to evacuate. In addition, due to the heavy flooding and because tens of home fuel tanks had broken loose and started leaking into rivers. A number of municipalities in Liège and Namur provinces were left without potable tap water. Around 41,000 households were left without electricity in Wallonia. Foundations of buildings near rivers became eroded and buildings collapsed. In the town of Pepinster on the banks of the river Vesder, at least 20 houses collapsed and 23 of the 31 casualties as of 18 July were found here. The town of Verviers was also badly affected and has more than 10,000 of its residents having to be moved because of homes having become inhabitable. Widespread looting has also been a problem.
Precipitation was most intense in the east of Belgium, with 271.5 millimetres (10.69 in) of rain over 48 hours in the municipality of Jalhay, in the province of Liège -- an absolute record for Belgium, almost three times the average rainfall over one month in this location for July. In the town of Spa, also in Liège, 217 millimetres (8.5 in) of rain fell over 48 hours. Large parts of the province of Luxembourg saw between 150 mm and 200 mm over 48 hours. In Flanders, the maximum rainfall was 77 millimetres (3.0 in) over 48 hours at Ransberg. In Dilsen-Stokkem, Limburg, the river Maas (Meuse) reached a flux of 3300 m3/s on 16 July, equalling the maximum flow that the local dykes are designed to withstand.[ citation needed ]
An empty passenger train derailed at Grupont when the track bed was washed out by floodwater, with debris strewn across the track.The Charleroi–Namur–Liège line, and all railway lines in Belgium south west of that line, were closed. The overall damage to the rail network was estimated to take several weeks to repair. Early estimates also pointed to severe damage to the agricultural sector of the country, including long-term effects like soil erosion. During the flooding itself, farms and livestock had to be evacuated and many fields were damaged and crops destroyed by inundation. The Circuit de Spa-Francorchamps suffered damage to access roads and its digital safety infrastructure. The circuit is due to hold the 2021 Belgian Grand Prix on 29 August.
Belgian Prime Minister Alexander De Croo declared 20 July a national day of mourning.
In the evening of 24th July, southern and central parts of Belgium were hit again by severe flashfloods as a result of intense but shorter thunderstorms. Particularly the city of Dinant and its surroundings in the province of Namur were badly hit, where tens of floating cars resulted in a pile-up and in damage to railroads.
The Slavonia region has been affected by floods. Communities such as Našice, Županja, Nova Gradiška, and Osijek were flooded and heavy rain caused serious damage, especially for farmers.No deaths were reported.
Heavy rainfall led to flooding especially in North Bohemia, and several communities near Česká Lípa had to be evacuated. The country promised emergency aid to those affected by the floods of up to 57,900 koruna (2270 euro).

No deaths were reported at this time.
With at least 177 deaths, As of 16 July 2021 [update] , at least 1,300 people were still missing, but mostly due to mobile networks being down in some regions which made it difficult to call people. It was considered unlikely that the number of deaths would rise that high, and while on 19 July the exact number of missing persons remained unclear, search was ongoing for at least 150 people. Some 15,000 police, soldiers and emergency service workers have been deployed in Germany to help with the search and rescue.the floods are the deadliest natural disaster in Germany since the North Sea flood of 1962.
During the floods, 128 people died in Rhineland-Palatinate (all of whom were in the district of Ahrweiler),47 in North Rhine-Westphalia (twenty-seven of whom in Euskirchen), and two in Bavaria. Four firefighters are among the dead. Westnetz, Germany's biggest power distribution grid, stated on 15 July that 200,000 properties in the North Rhine-Westphalia and Rhineland-Palatinate regions were without power, and that it would be impossible to repair substations until roads were cleared. On 16 July, around 102,000 people were still without power. The German Weather Service reported that the quantity of rain in some areas of Germany was the highest in over 100 years, possibly higher than any seen in the last 1,000 years. They reported that some areas had received a month's average rainfall in one day.
Some of the worst damage from the flood was in the district of Ahrweiler, Rhineland-Palatinate, where the river Ahr rose, destroying many buildings and causing at least 110 deaths. 1 metre (3.3 ft) to 7.85 metres (25.8 ft).The topography of Ahr valley in western Germany, with some sections resembling gorges, may have exacerbated the effects of the heavy rainfall. The flooding here was the worst since 1910 when up to 200 people were killed in flash flooding. On 14 July, the city of Hagen declared a state of emergency, after the Volme river started overflowing its banks. The village of Kordel in Trier-Saarburg, which has around 2,000 residents, has been completely cut off. Several rivers reached their highest water level to date, including the Kyll, which rose from an average level of

The cut-off low that caused the severe flooding across western Europe first moved over the United Kingdom on 12 July, resulting in more than the average monthly rainfall total to be recorded in a 24-hour period across parts of the country. Particularly severe flash flooding was reported in the London area, where 47.8 mm (1.88 in) of rainfall was recorded on 12 July at Kew, marking the third-wettest day on record for that weather station and the wettest since 6 July 1983. Both Putney in London and Chipstead in Surrey recorded more than 31 mm (1.2 in) of rainfall in a one-hour period, while other areas of London recorded over 76.2 mm (3.00 in) of rain in 90 minutes. The London Fire Brigade received more than 1,000 calls relating to flooding incidents, as houses were evacuated and cars were submerged by quickly rising floodwaters.
Heavy rainfall caused sewer systems to overflow, unable to handle the sudden intensity of the rainfall, resulting in streets and buildings being flooded by raw sewage. Thames Water received more than 2,500 calls relating to overflowing sewage, stating that the rainfall had surpassed the design capability of their sewage system; the heaviest rainfall occurred close to high tide, resulting in sewers that empty into the River Thames being unable to do so. 1.5 ft (0.46 m) in less than five minutes.In Notting Hill, floodwaters rose by
Sloane Square tube station was closed after floodwater from street level surged down stairways into the underground station; Chalk Farm, Hampstead and Wimbledon stations were also closed due to flooding.There was also a reduced level of service at Euston railway station, the London terminus of the West Coast Main Line and across the London Overground and Thameslink networks.

On 25 July, London was again hit by thunderstorms and flash floods. Areas affected included Camberwell, Clapham, Hackney Wick and Nine Elms.
German Chancellor Angela Merkel said she was "shocked by the catastrophe that so many people in the flood areas have to endure" and that her "sympathy goes out to the families of the dead and missing."Malu Dreyer, the minister-president of the Rhineland-Palatinate state, told the regional parliament: "There are people dead, there are people missing, there are many who are still in danger. We have never seen such a disaster. It's really devastating." On 16 July, the German Ministry of Defence declared a state of emergency in the parts of the country that were most affected. German Finance Minister Olaf Scholz on 17 July announced plans for a federal emergency aid of 300 million Euro.
The Belgian Minister of Home Affairs Annelies Verlinden described the events as "one of the greatest natural disasters our country has ever known" at a press conference on 19 July.On 15 July, the Belgian royal couple King Philippe and Queen Mathilde traveled to Chaudfontaine, which had been particularly badly hit by the flooding.
The President of the European Commission Ursula von der Leyen,the EU Council President Charles Michel and the European Commissioner for Crisis Management Janez Lenarčič all quickly provided statements of condolence for the victims and that the European Union was ready to help. After a Belgian request, the European Union Civil Protection Mechanism was activated on 14 July, and a helicopter and a flood rescue team was sent from France to Belgium immediately after this. The EU also provided satellite imagery and mapping of affected areas.
British Prime Minister Boris Johnson also said the UK was ready to provide assistance while Italy and Austria offered to send flood rescue teams to affected areas in Belgium.Pope Francis sent condolences, and was praying for those injured and missing, as well as those who had lost their livelihoods.
The Italian firefighters sent to Belgium to rescue the victims of the flood that hit Central Europe rescued at least 40 people in Tilff, an area south of Liège. Firefighters evacuated people who were stranded in their homes and in a nursing home.
The floods followed unprecedented heat waves in the Pacific Northwest and Northern Europe, prompting scientists to evaluate a possible connection to climate change.Prior to the floods, scientists had warned that extreme weather events would become more common as a consequence of climate change. Examples of such extreme events would include heavy rainfall; an increase in the atmosphere's temperature allows it to absorb more water vapour, resulting in more precipitation. Climate change might also have resulted in the jet stream becoming more erratic, which could lead to more frequent extreme weather phenomena. Further research and analysis are needed to understand the extent of climate change's role in the floods.
Antonio Navarra, climatologist at the University of Bologna and president of the Euro-Mediterranean Center foundation on Climate Change said that there is a clear correlation between the increase in the concentration of CO2 in the atmosphere and the frequency and intensity of floods, heat waves and drought periods.Carl-Friedrich Schleussner of Humboldt-Universität Berlin said the question was not whether climate change had contributed to the event, but rather "how much". Dieter Gerten, a researcher from the Potsdam Institute for Climate Impact Research, characterised the magnitude of the floods and other extreme weather events as exceeding predictions from current climate change models, noting that the abrupt increase in the frequency and intensity of extreme weather may indicate that a tipping point has been crossed. Michael E. Mann from Penn State University, Hayley Fowler of Newcastle University and Kai Kornhuber of Columbia University pointed to a slowing in the jet stream as a possible explanation. Stefan Rahmstorf of the University of Potsdam warned that further losses of Arctic ice would likely result in a weaker jet stream and more extreme weather, saying "we should not play with this sensitive climate system".
In the aftermath of the flooding, a spokesperson of the World Meteorological Organization called for more action against climate change.
A cloudburst is an extreme amount of precipitation in a short period of time, sometimes accompanied by hail and thunder, which is capable of creating flood conditions. Cloudbursts can quickly dump large amounts of water, e.g. 25 mm of precipitation corresponds to 25,000 metric tons per square kilometre. However, cloudbursts are infrequent as they occur only via orographic lift or occasionally when a warm air parcel mixes with cooler air, resulting in sudden condensation. At times, a large amount of runoff from higher elevations is mistakenly conflated with a cloudburst. The term "cloudburst" arose from the notion that clouds were akin to water balloons and could burst, resulting in rapid precipitation. Though this idea has since been disproven, the term remains in use.
Floods in the United States: 2001–present is a list of flood events which were of significant impact to the country since 2001, inclusive. Floods are generally caused by excessive rainfall, excessive snowmelt, storm surge from hurricanes, and dam failure.
A series of large floods occurred in parts of the United Kingdom during the summer of 2007. The worst of the flooding occurred across Scotland on 14 June; East Yorkshire and the Midlands on 15 June; Yorkshire, the Midlands, Gloucestershire, Herefordshire and Worcestershire on 25 June; and Gloucestershire, Herefordshire, Worcestershire, Oxfordshire, Berkshire and South Wales on 28 July 2007.
The 2009 European floods were a series of natural disasters that took place in June 2009 in Central Europe. Austria, the Czech Republic, Germany, Hungary, Poland, Romania, Serbia, Slovakia and Turkey were all affected. The heavy rains caused overflowing of the rivers Oder, Vistula, Elbe and Danube. At least 12 people were killed in the Czech Republic and one in Poland.
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.
Cyclone Andrea was an intense European windstorm that affected western and central Europe in early January 2012.
The Autumn of 2000 was the wettest recorded in the United Kingdom since records began in 1766. Several regions of Atlantic Europe from France to Norway received double their average rainfall and there were severe floods and landslides in the southern Alps. In October and November 2000 a successive series of extratropical cyclones caused severe flooding across the UK.
The 2012 Great Britain and Ireland floods were a series of weather events that affected parts of Great Britain and Ireland periodically during the course of 2012 and on through the winter into 2013. The beginning of 2012 saw much of the United Kingdom experiencing droughts and a heat wave in March. A series of low pressure systems steered by the jet stream brought the wettest April in 100 years, and flooding across Britain and Ireland. Continuing through May and leading to the wettest beginning to June in 150 years, with flooding and extreme events occurring periodically throughout Britain and parts of Atlantic Europe.
Extreme flooding in Central Europe began after several days of heavy rain in late May and early June 2013. Flooding and damages primarily affected south and east German states, western regions of the Czech Republic (Bohemia), and Austria. In addition, Croatia, Switzerland, Slovakia, Belarus, Poland, Hungary and Serbia (Vojvodina) were affected to a lesser extent. The flood crest progressed down the Elbe and Danube drainage basins and tributaries, leading to high water and flooding along their banks.
In late May and early June 2016 flooding began after several days of heavy rain in Europe, mostly Germany and France, but also Austria, Belgium, Romania, Moldova, Netherlands and the United Kingdom. Among others, the German states of Bavaria, Hesse, Rhineland-Palatinate, Baden-Württemberg, and North Rhine-Westphalia were affected. Beginning at the river Neckar, the Danube, Rhine, Seine and their tributaries were highly affected by high water and flooding along their banks. At least 21 people died in the floods.
Hurricane Harvey was a devastating Category 4 hurricane that made landfall on Texas and Louisiana in August 2017, causing catastrophic flooding and more than 100 deaths. It is tied with 2005's Hurricane Katrina as the costliest tropical cyclone on record, inflicting $125 billion in damage, primarily from catastrophic rainfall-triggered flooding in the Houston metropolitan area and Southeast Texas; this made the storm the costliest natural disaster recorded in Texas at the time. It was the first major hurricane to make landfall in the United States since Wilma in 2005, ending a record 12-year span in which no hurricanes made landfall at the intensity of a major hurricane throughout the country. In a four-day period, many areas received more than 40 inches (1,000 mm) of rain as the system slowly meandered over eastern Texas and adjacent waters, causing unprecedented flooding. With peak accumulations of 60.58 in (1,539 mm), in Nederland, Texas, Harvey was the wettest tropical cyclone on record in the United States. The resulting floods inundated hundreds of thousands of homes, which displaced more than 30,000 people and prompted more than 17,000 rescues.
Severe storm events in Sydney, New South Wales, Australia are not uncommon and include hailstorms, wind storms, and flash flooding from rain caused by East coast lows, black nor'easters and/or tropical cyclone remnants. East coast lows are low pressure depressions or extratropical cyclones that can bring significant damage by heavy rain, cyclonic winds and huge swells. Sydney is rarely affected by cyclones, although remnants of cyclones do affect the city.
The 2020 East Africa floods were a natural disaster in Rwanda, Kenya, Somalia, Burundi, Ethiopia, Uganda, Democratic Republic of Congo, Djibouti and Tanzania, affecting at least 700,000 people. They began when excessive rains began falling in March, leading to massive flooding and landslides. They caused more than 430 deaths, notably in Kenya and Rwanda. In the fall another round of floods hit the African Sahel.
Honduras, officially the Republic of Honduras, is a country in Central America. To the north of Honduras is Guatemala and Belize, to the south is Nicaragua, to the west is El Salvador, and to the east is the Caribbean Sea.
The Indonesia is an island country in Southeast Asia and Oceania, located in the Pacific and Indian Ocean. The largest island nation in the world, the country is the home of over seventeen thousand islands.
Extreme rainfall on the east coast of Australia beginning on 18 March 2021 led to widespread flooding in New South Wales, affecting regions from the North Coast to the Sydney metropolitan area in the south. Suburbs of Sydney experienced the worst flooding in 60 years, and the events were described by NSW Premier Gladys Berejiklian as "one in 100-year" flooding. Far-southeast communities in Queensland were also affected by flooding and heavy rainfall, though to a lesser extent than those in New South Wales.
Extremely Severe Cyclonic Storm Tauktae was a powerful, deadly and damaging tropical cyclone in the Arabian Sea that became the strongest tropical cyclone to make landfall in the Indian state of Gujarat since the 1998 Gujarat cyclone and one of the strongest tropical cyclones to ever affect the west coast of India. The second depression, first cyclonic storm, first severe cyclonic storm, first very severe cyclonic storm, and first extremely severe cyclonic storm of the 2021 North Indian Ocean cyclone season, Tauktae originated from a tropical disturbance, which was first monitored by the India Meteorological Department on May 13. The disturbance drifted eastward and organized into a deep depression by May 14. The storm soon took a northward turn, continuing to gradually intensify, and the system strengthened into a cyclonic storm and was named Tauktae later that same day. Tauktae continued intensifying into May 15, reaching severe cyclonic storm status later that day. Tauktae began to parallel the coast of the Indian states of Kerala, Karnataka, Goa and Maharashtra, before rapidly intensifying into a very severe cyclonic storm, early on May 16. Early on May 17, Tauktae intensified into an extremely severe cyclonic storm, reaching its peak intensity soon afterward. Later that same day, Tauktae underwent an eyewall replacement cycle and weakened, before restrengthening as it neared the coast of Gujarat, making landfall soon afterward.
Since 17 July 2021, China's Henan province has been affected by severe flooding, caused by a period of prolonged heavy rainfall. Record-breaking maximum rainfall of 201.9 millimetres (7.95 in) in an hour was observed in Zhengzhou, the provincial capital. 19 weather stations in the province renewed their daily rainfall records. As of 25 July 2021, at least 63 people were killed, at least 5 went missing, 815,000 people were evacuated, 1.1 million were relocated, and 9.3 million people were affected. The floods were made more likely by increases in extreme weather caused by climate change in China.
