New York, October 30: Superstorm Sandy slammed into the New Jersey coastline with 80 mph winds on Monday night and hurled an unprecedented 13-foot surge of seawater at New York City, flooding its tunnels, subway stations and the electrical system that powers Wall Street. At least 13 US deaths were blamed on the storm, which brought the presidential campaign to a halt a week before election day.

For New York City at least, Sandy was not the dayslong onslaught many had feared, and the wind and rain that sent water sloshing into Manhattan from three sides began dying down within hours.

Still, the power was out for hundreds of thousands of New Yorkers and an estimated 5.7 million people altogether across the East. And the full extent of the storm's damage across the region was unclear, and unlikely to be known until daybreak.

In addition, heavy rain and further flooding remain major threats over the next couple of days as the storm makes its way into Pennsylvania and up into New York State. Near midnight, the center of the storm was just outside Philadelphia, and its winds were down to 75 mph, just barely hurricane strength.

"It was nerve-racking for a while, before the storm hit. Everything was rattling," said Don Schweikert, who owns a bed-and-breakfast in Cape May, NJ, near where Sandy roared ashore. "I don't see anything wrong, but I won't see everything until morning."

As the storm closed in, it converged with a cold-weather system that turned it into a superstorm, a monstrous hybrid consisting not only of rain and high wind but snow in West Virginia and other mountainous areas inland.

It smacked the boarded-up big cities of the Northeast corridor - Washington, Baltimore, Philadelphia, New York and Boston - with stinging rain and gusts of more than 85 mph.

Just before Sandy reached land, forecasters stripped it of hurricane status, but the distinction was purely technical, based on its shape and internal temperature. It still packed hurricane-force wind, and forecasters were careful to say it was still dangerous to the tens of millions in its path.

Sandy made landfall at 8pm near Atlantic City, which was already mostly under water and saw an old, 50-foot piece of its world-famous Boardwalk washed away earlier in the day.

Authorities reported a record surge 13-feet high at the Battery at the southern tip of Manhattan, from the storm and high tide combined.

In an attempt to lessen damage from saltwater to the subway system and the electrical network beneath the city's financial district, New York City's main utility cut power to about 6,500 customers in lower Manhattan. But a far wider swath of the city was hit with blackouts caused by flooding and transformer explosions.

The city's transit agency said water surged into two major commuter tunnels, the Queens Midtown and the Brooklyn-Battery, and it cut power to some subway tunnels in lower Manhattan after water flowed into the stations and onto the tracks.

The subway system was shut down on Sunday night, and the stock markets never opened on Monday and are likely to be closed on Tuesday as well.

The surge hit New York City hours after a construction crane atop a luxury high-rise collapsed in the wind and dangled precariously 74 floors above the street. Forecasters said the wind at the top the building may have been close to 95 mph.

As the storm drew near, airlines canceled more than 12,000 flights, disrupting the plans of travelers all over the world.

Storm damage was projected at $10 billion to $20 billion, meaning it could prove to be one of the costliest natural disasters in US history.

Thirteen deaths were reported in New Jersey, New York, West Virginia, Pennsylvania and Connecticut. Some of the victims were killed by falling trees. At least one death was blamed on the storm in Canada.

President Barack Obama and Republican challenger Mitt Romney canceled their campaign appearances at the very height of the race, with just over a week to go before election day. The president pledged the government's help and made a direct plea from the White House to those in the storm's path.

"When they tell you to evacuate, you need to evacuate," he said. "Don't delay, don't pause, don't question the instructions that are being given, because this is a powerful storm."

Sandy, which killed 69 people in the Caribbean before making its way up the Atlantic, began to hook left at midday toward the New Jersey coast.

New Jersey gvoernor Chris Christie said people were stranded in Atlantic City, which sits on a barrier island. He accused the mayor of allowing them to stay there. With the hurricane roaring through, Christie warned it was no longer safe for rescuers, and advised people who didn't evacuate the coast to "hunker down" until morning.

"I hope, I pray, that there won't be any loss of life because of it," he said.

While the hurricane's 90 mph winds registered as only a Category 1 on a scale of five, it packed "astoundingly low" barometric pressure, giving it terrific energy to push water inland, said Kerry Emanuel, a professor of meteorology at MIT.

And the New York metropolitan area apparently got the worst of it, because it was on the dangerous northeastern wall of the storm.

"We are looking at the highest storm surges ever recorded" in the Northeast, said Jeff Masters, meteorology director for Weather Underground, a private forecasting service. "The energy of the storm surge is off the charts, basically."

Hours before landfall, there was graphic evidence of the storm's power.

Off North Carolina, a replica of the 18th-century sailing ship HMS Bounty that was built for the 1962 Marlon Brando movie "Mutiny on the Bounty" went down in the storm, and 14 crew members were rescued by helicopter from rubber lifeboats bobbing in 18-foot seas. Another crew member was found hours later but was unresponsive. The captain was missing.

At Cape May, water sloshed over the seawall, and it punched through dunes in other seaside communities.

"When I think about how much water is already in the streets, and how much more is going to come with high tide tonight, this is going to be devastating," said Bob McDevitt, president of the main Atlantic City casino workers union. "I think this is going to be a really bad situation tonight."

In Maryland, at least 100 feet of a fishing pier at the beach resort of Ocean City was destroyed.

At least half a million people along the East Coast had been ordered to evacuate, including 375,000 from low-lying parts of New York City.

Sheila Gladden left her home in Philadelphia's flood-prone Eastwick neighborhood, which took on 5 1/2 feet of water during Hurricane Floyd in 1999, and headed for a hotel.

"I'm not going through this again," she said.

Those who stayed behind had few ways to get out.


Not only was the New York subway shut down, but the Holland Tunnel connecting New York to New Jersey was closed, as was a tunnel between Brooklyn and Manhattan. The Brooklyn Bridge, the George Washington Bridge, the Verrazano-Narrows Bridge and several other spans were closed because of high winds.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

Shanghai, Jan 27: The death toll from a coronavirus outbreak in China rose to 81 on Monday, as the government extended the Lunar New Year holiday and more big businesses shut down or told staff to work from home in an effort to curb the spread.

Chinese Premier Li Keqiang visited the central city of Wuhan, the epicenter of the outbreak, as the government sought to signal it was responding seriously to the crisis.

The total number of confirmed cases in China rose about 30% to 2,744, about half of them in Hubei province, whose capital is Wuhan.

As worries grew around the world, Chinese-ruled Hong Kong, which has had eight confirmed cases, banned entry to people who had visited Hubei in the past 14 days. The ban did not cover Hong Kong residents.

The number of deaths from the flu-like virus in Hubei climbed to 76 from 56, health officials said, with five deaths elsewhere in China, including the southern island province of Hainan, which reported its first fatality on Monday.

While a small number of cases have been confirmed in more than 10 countries, linked to people who traveled from Wuhan, no deaths have been reported elsewhere.

Li is the most senior leader to visit Wuhan since the outbreak began. Clad in a blue protective suit and mask, he inspected efforts to contain the epidemic and spoke to patients and medical staff, the government said.

The government is extending the week-long Lunar New Year holiday by three days to February 2, in a bid to slow the spread of the virus. The Lunar New Year is usually a time for millions of people to travel, but many have had to cancel their plans because of travel curbs over the virus.

Incubation

Wuhan is already in virtual lockdown and severe limits on movement are in place in several other Chinese cities.

The city of 11 million clamped down further on Monday, announcing the suspension of visa and passport services until January 30.

Despite the curbs, the mayor of Wuhan said on Sunday that five million people had left the city for holidays and other reasons.

Images from Wuhan showing hospital corridors packed with people seeking treatment have circulated on social media, along with complaints of soaring prices for essentials such as vegetables.

Chinese leaders have urged transparency in the crisis, after public trust was eroded by the cover-up of the spread of Severe Acute Respiratory Syndrome (SARS), a coronavirus that originated in China and killed nearly 800 people globally in 2002 and 2003.

Much is not known about the newly identified coronavirus, including how easily it spreads and just how dangerous it is. It can cause pneumonia, which has been deadly in some cases.

National Health Commission minister Ma Xiaowei said on Sunday the incubation period could range from one to 14 days, and the virus was infectious during incubation, unlike SARS.

That compares with a World Health Organization (WHO) estimate of two to 10 days for the incubation period.

“Understanding the time when infected patients may transmit the virus to others is critical for control efforts,” the WHO said.

The virus is believed to have originated late last year in a Wuhan market illegally selling wildlife. It has spread to other cities, including Beijing and Shanghai, as well as more than 10 countries including France, Japan and the United States.

‘Overwhelmed’

Australia confirmed its fifth case on Monday involving a woman on the last flight out of Wuhan to Sydney before China’s travel ban.

Health minister Greg Hunt told the Australian Broadcasting Corporation (ABC) authorities aimed to get about 100 Australian children and young people out of Wuhan.

One father of two, Nathan Wang, told the ABC his wife was stuck in Wuhan with the children. “We absolutely want the children to come back, because hospitals in Wuhan are overwhelmed,” he said.

Airports around the world have stepped up screening of passengers from China, although some health experts have questioned its effectiveness.

Last week the WHO stopped short of calling the outbreak a global health emergency, but some health experts question whether China can contain the epidemic.

WHO Director-General Tedros Adhanom Ghebreyesus is due to travel to Beijing to meet officials and health experts.

Australia, France, Italy, Japan and the United States have all said they are working to evacuate citizens from Wuhan.

Some of China’s biggest companies have been affected, with hotpot restaurant chain Haidilao International Holding shutting branches nationwide from Sunday until Friday.

Gaming giant Tencent Holdings Ltd advised staff to work from home until February 7, and e-commerce firm Alibaba removed vendors’ offers of overpriced face masks from its online Taobao marketplace as prices surged.

May 22: A Pakistan International Airlines (PIA) flight on its way from Lahore to Karachi, crashed in the area near Jinnah International Airport on Friday, according to Civil Aviation Authority officials.

Geo News reported that the plane crashed at the Jinnah Ground area near the airport as it was approaching for landing. There were more than 90 passengers on board the Airbus aircraft. Black smoke could be seen from afar at the crash site, say eye witnesses.

There were no immediate reports on the number of casualties. The aircraft arriving from the eastern city of Lahore was carrying 99 passengers and 8 crew members, news agency AP said, quoting Abdul Sattar Kokhar, spokesman for the country’s civil aviation authority.

Witnesses said the Airbus A320 appeared to attempt to land two or three times before crashing in a residential area near Jinnah International Airport.

Flight PK-303 from Lahore was about to land in Karachi when it crashed at the Jinnah Garden area near Model Colony in Malir, just a minute before its landing, Geo News reported.

Local television reports showed smoke coming from the direction of the airport. Ambulances were on their way to the airport.

News agency said Sindh’s Ministry of Health and Population Welfare has declared emergency in all major hospitals of Karachi due to the plane crash.

It’s the second plane crash for Pakistani carrier in less than four years. The airline’s chairman resigned in late 2016, less than a week after the crash of an ATR-42 aircraft killed 47 people. The incident comes as Pakistan was slowly resuming domestic flights in the wake of the coronavirus pandemic, Bloomberg reported.
