In France, hundreds of thousands of people are still without electricity in their homes as the storm rages on.


Record-breaking rain produced floods in a vast swath of Italy's Tuscany region as Storm Ciarán pushed into the country overnight, trapping residents in their homes, inundating hospitals and overturning cars.


At least six people in Italy and one person in Albania have been killed, bringing the storm’s death toll to 14 across Europe this week.


In Albania, police said a motorist died when he lost control while driving a car, which slid and hit barriers. Many roads in the country were flooded, including in the capital, Tirana.


Huge waves pummelling the Adriatic shores of the Balkans, and strong winds uprooted trees and ripped off roofs. Ferries connecting Croatia's islands with the coastline were halted.


Italian Civil Protection authorities said that 200 millimetres (nearly eight inches) of rain fell in a three-hour period, from the coastal city of Livorno to the inland valley of Mugello, and caused riverbanks to overflow. Video showed at least a dozen cars getting swept away down a flooded road.


Tuscany Governor Eugenio Giani said that six people died in the storm, which dumped an amount of rainfall not recorded in the last 100 years.


In France, some 260,000 homes were still without electricity on Saturday morning, mainly in Brittany and Normandy, after the passage of storm Ciaran, electricity company Enedis reported.


“At 8 a.m., 260,000 customers remain to be replenished, particularly in Brittany (200,000) and Normandy (51,000),” the company said in a press release.


More than 1.2 million households have been affected by the storm, with electricity restored to 875,000 homes late on Friday.


Storm Ciaran claimed the lives of at least two people in France and left damage that will take several days to resolve.


Emmanuel Macron, who visited Finistère on Friday, the most affected region, called on the French to “remain extremely vigilant” in the coming days.


“We have a fight, which is to restore normal life as quickly as possible,” the President added, aiming in particular to restore electricity to 90% of affected households by Monday.


Météo-France will place 10 new departments on orange alert on Saturday evening as Storm Domingos approaches, which will cause “violent gusts of wind” on the Atlantic coast, meteorologists said.


Climate scientists say human-induced climate change has led to heavier rainfall during storms like Ciarán, often resulting in more severe damage.


 Storm Ciaran whips western Europe, blowing record winds in France and leaving millions without power.

Winds up to 180 kilometers per hour (108 mph) slammed France's Atlantic coast overnight as Storm Ciaran lashed countries around western Europe, uprooting trees, blowing out windows and leaving 1.2 million French households without electricity Thursday 2 November2023.

Heavy rain associated with the storm pushed ashore at the southwest tip of England, and the UK's national weather forecaster warned of flood risks and urged people to take precautions. Dutch airline KLM scrapped all flights from the early afternoon until the end of the day, citing the high sustained wind speeds and powerful gusts expected in the Netherlands.


A weather-related death has already been confirmed in France. A truck driver was killed when his vehicle was hit by a tree in northern France's inland Aisne region, Transport Minister Clement Beaune said.


Nearly all coastlines of the French mainland were under severe weather warnings Thursday morning, from Calais on the English Channel to all the way down the shores of the Atlantic Ocean to Spain, as well as much of France’s Mediterranean coast and Corsica, according to national weather service Météo-France.

The weather service reported record-breaking wind speeds of 180 kilometres per hour along the Brittany coast. The wind reached up to 160 kph on the Normandy coast and up to 150 kph inland. Waves of almost 10 metres were expected in the country’s northwestern tip.


Local trains were cancelled across a swath of western France, and all roads in the Finistere region of Brittany were closed Thursday morning. Beaune urged people to avoid driving and to at least exercise caution when travelling across areas with weather warnings.


‘’We see how roads can be fatal in these circumstances,’’ he told broadcaster France-Info.


Deadly flooding and 200kph winds: Did climate change fuel Storm Ciarán's record breaking weather?

The storm cut power to some 1.2 million French households as of Thursday morning, electrical utility Enedis announced in a statement. That includes about half of the homes in Brittany, the Atlantic peninsula hardest hit by Ciaran. Enedis said it would deploy 3,000 workers to restore power as soon as weather conditions allowed.


The national train authority, the SNCF, cancelled some regional trains in five eastern regions starting late Wednesday night. Fast trains from Paris were eliminating intermediary stops on the route to Rennes and several other destinations.


In the UK, southern England and the Channel Islands were expected to take the worst of the storm. Flooding was expected in 54 areas, according to the Environment Agency, most of them on England's southern coast.


Schools were closed in some coastal areas as a precaution. The UK’s Met Office issued severe weather warnings for high waves and winds of about 130 kilometres per hour or more.


“Trees are in leaf at the moment, so they are more top-heavy,” Rachel Ayers, a senior meteorologist at the Met Office, said, as the storm approached Wednesday. “That does increase the risk of them falling over and also with the leaves around that makes (for) increased drainage issues.”

Authorities urged people in southern England to work from home, and train companies advised passengers not to travel on routes in and out of London before 9 a.m. Thursday as tracks were checked for fallen trees and debris, according to the Press Association news agency.


The blustery weather is the result of a branch of the jet stream - a consistent band of strong wind high above the Earth’s surface heading west to east - heading towards northern Europe, Henson said. The storm is caused by an interaction between what’s going on near the surface and a few miles above ground.


“It looks like a once-in-every-few-years storm for the UK and France,” Bob Henson, a meteorologist and science writer with Yale Climate Connections, said but Ciaran could turn into “a once-in-a-generation storm.”


From sirens to text messages: Why extreme weather warnings are needed more than ever

Friederike Otto of Imperial College London’s Grantham Institute for Climate Change and the Environment studies the extent to which extreme weather events are caused by global warming.


She said there have been few studies on whether wind speeds were increasing because of climate change, and understanding is hampered by the fact that there were few observations of wind speeds taken far back in the past.


But the rainfall associated with such storms has increased due to human-induced climate change, she said. That’s because a warmer atmosphere can hold more moisture which must fall as rain. On that, the science was “quite clear,” she said, with a 7% increase in rainfall for each degree Celsius of global warming.


Heavier rain leads to more damage, and rising sea levels due to global warming also lead to more damaging storm surges, she said.

 伦敦帝国理工学院格兰瑟姆气候变化与环境研究所的弗里德里克·奥托研究了全球变暖导致极端天气事件的程度。

 她说,关于风速是否因气候变化而增加的研究很少,并且由于很少对过去的风速进行观测,这一事实阻碍了理解。

 但她说,由于人类引起的气候变化,与此类风暴相关的降雨量有所增加。 这是因为温暖的大气可以容纳更多的水分,这些水分必须以雨的形式落下。 她说,关于这一点,科学“非常清楚”,全球变暖每升高一度,降雨量就会增加 7%。

 她说,大雨会导致更大的破坏,全球变暖导致的海平面上升也会导致更具破坏性的风暴潮。

SEVERE WEATHER

The Most Extreme Winds Recorded on Earth 

Tropical Cyclone Olivia.


In April 1996, Tropical Cyclone Olivia bore down on Barrow Island, Australia. An individual mesovortex within Olivia's eyewall produced five extreme three-second wind gusts, the peak of which was a 253 mph gust on April 10.


For reference, this brief gust was more than 11 mph faster than the Indy car world record of 241.428 mph by Gil de Ferran in 2000. 

Category 4 hurricane.


After an investigation by the World Meteorological Organization, this was accepted as a world record for a tropical cyclone surface wind gust. Less than two years later, this gust was found to be less than that which occurred in Tropical Cyclone Olivia in 1996.


Also of note, this western Cuba station reported a one-minute sustained wind of 155 mph, bordering on Category 5 status.


The Strongest U.S. Hurricane Wind Gust on Record

The strongest U.S. hurricane wind gust recorded must have come from one of the only three hurricanes to make a Category 5 U.S. landfall, right Not exactly, as the key word here is "recorded."
