When the lights go out: How to prepare for a massive power outage
While such longer nationwide outages are extremely rare, it can never hurt to be prepared. Because when the power goes out, that doesn't only mean the lights go out.
Here's a selection of basic amenities that will be impacted by a power outage:
The main water supply, including the toilet flush. At worst, there is only enough water left in the tank to flush once.
Mobile networks and landlines. While you might have a full phone battery and the mobile network has an emergency power supply, both will run out eventually. Landlines will also be down shortly after a blackout.
ATMs and supermarket checkouts won't work either, so you won't be able to take out cash or stock up on groceries at short notice.
Petrol stations, as their fuel pumps also run on electricity.
Local and long-distance public transport.
Heating.
Your doorbell.
What to stock for an emergency
There are several things you can do to prepare for a prolonged power cut.
Prepare, a British government campaign providing tips on what actions to take before and during a power outage, recommends keeping a battery or wind-up torch as well as spare batteries at home as using your phone's torch will quickly drain the battery.
A battery or wind-up radio is also essential, according to the experts, as it will allow you to receive updates on the blackout when the internet is down.
You should also consider storing some bottled water and non-perishable food. Germany's civil protection agency recommends keeping at least 1.5 litres of water per day and adult so you have enough to drink and brush your teeth. Add another half a litre for cooking.
In terms of food, the experts at Prepare recommend to stock up on ready-to-eat tinned food, including fruit and vegetables that doesn't require cooking. Make sure you have a tin opener.
Dried fruit, nuts and granola bars are also handy to have at home, the German agency notes. Don't forget to stock up on baby formula and baby food or pet food if needed.
To be able to heat up your food, consider keeping a gas-powered camping stove at home, though you should make sure never to use it indoors due to a risk of poisoning.
Having a stash of cash at home can prove immensely helpful during a power outage, as it will allow you to make purchases even if checkouts are down.
Last not but least, make sure you have warm clothes, a first-kid aid and a supply of all the medication you need.
What do do in case of a blackout
Once the lights are out, you can try to reach out to your network operator, local fire brigade or municipality for information or help.
Use your battery-powered radio to receive news updates.
The Prepare campaign urges people to stay away from power lines, and turn of electric appliances including irons, ovens, electric fires and fryers. You should also unplug your TV and computer "as they can be damaged if there is a surge when power goes back on."
Make sure to check in on vulnerable people, including neighbours. To be able to coordinate without your phones, it might be worth discussing with your family beforehand where to meet up in case of a blackout.
Last but not least, try to keep calm, as the power will come back eventually.

What in-flight turbulence is and when it becomes dangerous for passengers and crews
Turbulence Explainer A Delta Air Lines flight from Salt Lake City to Amsterdam that was hit by serious turbulence Wednesday, sending 25 people on board to hospitals and forcing the flight to divert to Minnesota, highlighted the dangers of flying through unstable air. Several turbulence-impacted flights have been reported this year. While turbulence-related fatalities are quite rare, the tally of injuries has grown over the years. Some meteorologists and aviation analysts note that reports of turbulence encounters also have been increasing and point to what climate change may be doing to flying conditions. Planes hitting bumpy air is mostly minor, however, and airlines have tried to improve safety. Experts advise travelers to stay vigilant, stressing wearing a seat belt whenever possible. What causes turbulence Turbulence is essentially unstable air that moves in a non-predictable fashion. Most people associate it with heavy storms. But the most dangerous is clear-air turbulence, which often occurs with no visible warning. Clear-air turbulence happens most often in or near the high-altitude rivers of air called jet streams. The culprit is wind shear, which is when two huge air masses close to each other move at different speeds. If the difference in speed is big enough, the atmosphere can't handle the strain, and it breaks into turbulent patterns like eddies in water. Recent flights shaken by turbulence In June, five people were taken to a North Carolina hospital for evaluation after an American Airlines flight from Miami hit turbulence on its way to Raleigh-Durham International Airport. The plane landed safely. Earlier that month, severe storms in southern Germany forced a Ryanair flight to make an emergency landing after violent turbulence injured nine people, German police said. The flight was traveling from Berlin to Milan with 179 passengers and six crew members. Eight passengers and one crew member were hurt. In March, a United Airlines flight from San Francisco to Singapore experienced severe turbulence over the Philippines. The plane was carrying 174 passengers and 14 crew members. Five people were injured and the plane landed safely in Singapore. Several flights were diverted to Waco, Texas, on March 3, because of turbulence. Five people were injured aboard a United Express plane flying from Springfield, Missouri, to Houston. Last year, Italian authorities launched an investigation after two easyJet flight attendants were injured when their flight from Corfu to London's Gatwick Airport was buffeted by turbulence. The pilot made an unscheduled landing in Rome. In May 2024, a 73-year-old British man died and dozens of people were injured aboard a Singapore Airlines flight that hit severe turbulence. His death was under investigation. Authorities said he may have had a heart attack. It's unclear how common injuries are Tracking the number of turbulence-related injuries worldwide is difficult. But some countries publish national data. Most reports of in-flight turbulence from 2009 through 2018 resulted in one or more serious injuries and no damage to the plane, the National Transportation Safety Board reported. Between 2009 and 2024, 207 people were injured seriously enough during turbulence to require hospital treatment for at least two days, according to the NTSB. Most of them were flight attendants, who are more likely to be out of their seats during a flight. How pilots try to avoid it Pilots try to avoid turbulence partly by using a weather radar display. Sometimes they can simply see and fly around thunderstorms. But clear-air turbulence 'is altogether another animal,' said Doug Moss, a former airline pilot and safety consultant. It can be devastating, he said, 'because the time before the incident can be very calm, and people are caught off-guard.' Air traffic controllers will warn pilots after another plane runs into clear-air turbulence, Moss said. Many pilots also look for signs of wind shear, then plan to avoid those areas, he said. Modern planes are strong enough to handle just about any turbulence. Cabin areas such as overhead bins may receive cosmetic damage, 'but these don't impact the structural integrity of the planes,' Moss said. Scientists look at climate change's influence Some scientists note that reports of turbulence encounters are on the rise. Several researchers have pointed to potential climate impacts as one of the possible explanations. Professor Thomas Guinn, of Embry-Riddle Aeronautical University, explains that some predict climate change could alter the jet stream and up the wind shear, which would drive up turbulence. Paul Williams, a professor of atmospheric science at the University of Reading in England, said there was 'strong evidence that turbulence is increasing because of climate change.' Williams said in a statement last year that his research team discovered that severe clear-air turbulence in the North Atlantic has increased by 55% since 1979, for example. The team's projections signal that severe turbulence in the jet streams could double or triple in the coming decades if global conditions continue as expected, he said. There could be a rise in overall air traffic that may increase turbulence encounters as the number of flight tracks go up, said Larry Cornman, a project scientist at the National Science Foundation's National Center for Atmospheric Research. What travelers can do to stay safe In short, buckle up. Turbulence can be tricky to predict, but experts stress that the first line of defense is keeping the seat belt fastened, whenever possible. And airlines have taken steps for safety. Last November, Southwest Airlines said it was ending cabin service earlier so that passengers return to their seats and fasten seat belts sooner. The change was intended to 'reduce the risk of in-flight turbulence injuries,' the company said. Also last year, Korean Air decided to stop offering a beloved instant noodle, Shin Ramyun. 'This decision is part of proactive safety measures in response to increased turbulence, aimed at preventing burn accidents,' the Seoul-based airline said in a statement. Solve the daily Crossword

British brother and sister, 11 and 13, drown off beach in Spain
A British brother and sister, aged 11 and 13, have died after drowning off a beach on the east coast of Spain, according to local authorities. The two children, along with their father, were pulled from the water at Llarga beach in Salou, Tarragona by emergency services on Tuesday evening. "Tragically, the boy and girl could not be saved despite the best efforts of rescuers," said the head of the local police force, José Luis Gargallo. He added that the father survived "although he had swallowed a large amount of water and was in a state of exhaustion". Officials earlier reported that the children who died had both been boys, rather than a boy and a girl. "The sea was rough, and people sometimes underestimate its power - especially in this area, which is usually very calm," said Mr Gargallo. "Ninety percent of the time, there is no danger on that beach, and it is considered an ideal spot for swimming. But [Tuesday] was different - not just at that beach, but along the entire coast." Lifeguards on the beach had finished by the time the emergency call came in about the drowning children shortly before 21:00. Mr Gargallo said the children and father were from a family of five, and that the mother and other children were back at their hotel nearby. He added that authorities would "review everything" and take steps to prevent any similar future incidents. Speaking to the BBC, local authorities in Salou said they were deeply saddened by Tuesday night's tragedy. A minute's silence was held outside Salou town hall just before midday on Wednesday. Police earlier said sea conditions were rough and the beach had a yellow flag throughout the day - meaning swimming is allowed but caution is advised - local media reported. Seven medical units were dispatched to the scene and police and fire services also attended. Authorities also sent a team of psychologists to support the family. A 54-year-old German man also drowned on Tuesday at the beach of Cap de Sant Pere de Cambrils, a short distance along the coast from Llarga beach. The deaths bring the number of fatalities on Catalan beaches to 16 since the summer season began on 15 June - five more than the same period last year, officials added. A spokesperson for the UK Foreign Office said: "We are supporting the family of two British children who have died in Spain and are in contact with the local authorities." The civil protection force urged "the importance of taking extreme precautions on beaches, swimming pools and inland waters this summer". According to figures from the Salou municipality, around 1.3 million British tourists visit the town each year. It comes after a number of other British deaths in Spain this summer. Two British men, aged 19 and 26, died in separate incidents at a hotel and music venue in Ibiza earlier this month.
