Dubai flooding hobbles major airport's operations as "historic weather event" brings torrential rains to UAE

 Dubai flooding hobbles major airport's operations as "historic weather event" brings torrential rains to UAE





Dubai, United Arab Emirates — The desert nation of the United Arab Emirates attempted to dry out Wednesday from the heaviest rain ever recorded there after a deluge flooded out Dubai International Airport, disrupting travel through the world's busiest airfield for international travel. The state-run WAM news agency called the rain Tuesday "a historic weather event" that surpassed "anything documented since the start of data collection in 1949." 

The rains began late Monday, soaking the sands and roadways of Dubai with some 0.79 inches of rain, according to meteorological data collected at Dubai International Airport. The storms intensified around 9 a.m. local time Tuesday and continued throughout the day, dumping more rain and hail onto the overwhelmed city.


Flooding impacts Dubai International Airport

By the end of Tuesday, more than 5.59 inches of rainfall had soaked Dubai over 24 hours. An average year sees just 3.73 inches of rain fall at Dubai International Airport, a hub for the long-haul carrier Emirates.

At the airport, standing water lapped on taxiways as aircraft landed. Arrivals were halted Tuesday night and passengers struggled to reach terminals through the floodwater covering surrounding roads.

The airport said in a series of social media posts that all operations were halted for about 25 minutes on Tuesday afternoon and that all arrivals would be diverted after that "until the weather conditions improve." Late Wednesday morning, the airport and the flagship carrier Emirates were still warning travelers not to come to the airport unless absolutely necessary, saying all flight check-in was still suspended.

"Flights continue to be delayed and diverted. Please check your flight status directly with your airline," the airport said in a tweet. "We are working hard to recover operations as quickly as possible in very challenging conditions." 


One couple, who spoke to The Associated Press on condition of anonymity in a country with strict laws that criminalize critical speech, called the situation at the airport "absolute carnage."

"You cannot get a taxi. There's people sleeping in the Metro station. There's people sleeping in the airport," the man said Wednesday.

They ended up getting a taxi to near their home some 18 miles away, but floodwater on the road stopped them. A bystander helped them over a highway barrier with their carry-on luggage, the bottles of gin they picked up from a duty-free store clinking away.

Passengers wait at a flight connection desk at Dubai International Airport, April 17, 2024, amid flight delays and cancelations caused by flash flooding brought by a historic rain storm.


Paul Griffiths, the airport's CEO, acknowledged continued issues with flooding Wednesday morning, saying every place an aircraft could be safely parked was taken. Some aircraft had been diverted to Al Maktoum International Airport at Dubai World Central, the city-state's second airfield.

"It remains an incredibly challenging time. In living memory, I don't think anyone has ever seen conditions like it," Griffiths told the state-owned talk radio station Dubai Eye. "We are in uncharted territory, but I can assure everyone we are working as hard as we possibly can to make sure our customers and staff are looked after."


Did "cloud-seeding" contribute?

Rain also fell in Bahrain, Oman, Qatar and Saudi Arabia. However, the rains were acute across the UAE. One reason may have been "cloud seeding," in which small planes flown by the government go through clouds burning special salt flares. Those flares can increase precipitation.

Several reports quoted meteorologists at the National Center for Meteorology as saying they flew six or seven cloud-seeding flights before the rains. The center did not immediately respond to questions Wednesday, though flight-tracking data analyzed by the AP showed one aircraft affiliated with the UAE's cloud-seeding efforts flew around the country Sunday.

The UAE, which relies heavily on energy-hungry desalination plants to provide water, conducts cloud seeding in part to increase its dwindling, limited groundwater.


Flooding closes schools across UAE

Schools across the UAE, a federation of seven sheikhdoms, largely shut ahead of the storm and government employees were largely working remotely if they could. Many workers stayed home as well, though some ventured out, with the unfortunate ones stalling out their vehicles in deeper-than-expected water covering some roads.

Authorities sent tanker trucks out into the streets and highways to pump away the water. Water poured into some homes, forcing people to bail out their houses.

The country's hereditary rulers offered no overall damage or injury information for the nation, as some people slept in their flooded vehicles Tuesday night. In Ras al-Khaimah, the country's northernmost emirate, police said a 70-year-old man died when his vehicle was swept away by floodwater.

Fujairah, an emirate on the UAE's eastern coast, saw the heaviest rainfall Tuesday with 5.7 inches falling there.

Authorities canceled school and the government instituted remote work again for Wednesday.

Rain is unusual in the UAE, an arid, Arabian Peninsula nation, but occurs periodically during the cooler winter months. Many roads and other areas lack drainage given the lack of regular rainfall, causing flooding.

Meanwhile in neighboring Oman, a sultanate that rests on the eastern edge of the Arabian Peninsula, at least 19 people were killed in heavy rains in recent days, according to a statement Wednesday from the country's National Committee for Emergency Management. That includes some 10 schoolchildren swept away in a vehicle with an adult, prompting condolences from rulers across the region.

How to photograph April 8's solar eclipse with a camera or a smartphone

"Eclipse Across America," will air live Monday, April 8, beginning at 2 p.m. ET on ABC, ABC News Live, National Geographic Channel, Nat Geo WILD, Disney+ and Hulu as well as network social media platforms.

The historic total solar eclipse on April 8 is set to be one of the most photographed events this year.

In the U.S., 31 million people already live inside the path of totality and millions are likely to travel to cities within that path, watching the moon pass over and then completely block the face of the sun for a short period.

It's a phenomenon that almost every viewer will want to capture in a photograph, but it may be difficult to figure out what's the best gear to use or how to set up.

Photographer Stan Honda, who is based in New York City, has photographed three total solar eclipses and at least 10 partial solar eclipses. He gave his tips to ABC News on the best ways to capture this rare celestial event.

Before you start taking pictures, wear eclipse glasses


One of the most important things, before and as you are setting up equipment, is to never look up at phases of the partial eclipse -- when the moon is partly obscuring the sun -- without wearing eclipse glasses.

Looking up with the naked eye or regular sunglasses can burn the retina, leading to long-lasting -- even permanent -- damage. The glasses can only be removed during the totality period, when the sun is completely blocked by the moon.

Make sure the glasses are certified ISO 12312-2, which is the international safety standard for products designed for direct viewing of the sun.

This standard does not apply to solar filters that fit in the front of devices such as camera lenses, so make sure you're purchasing a proper solar filter to fit when photographing the partial phases of the eclipse.

Keep the setup simple
If you'll be taking photographs with a professional or digital camera, Honda recommends keeping the set-up as simple as possible.

The type of lens you use will depend on what kind of photographs you would like to capture, but Honda says he tries to use two types of lenses for his photographs.

The first is a long telephoto lens to get a close view of the sun during the eclipse and the second is a wider angle lens to capture both the eclipse and the landscape around you.

"To me, that's almost a more interesting picture because it places the eclipse in a location," he said of the wider-angle photographs. "When you zoom in and when you do close-ups of the sun, it isolates it up in space, and you're not really sure where you are. The wide-angle ones really show the location where you are, and often can show people, things like that."

For amateur photographers, or those experiencing their first total solar eclipse, Honda recommends using just one camera, one lens and a tripod.

"I always tell people, especially if this is your first total eclipse, try not to think too much about the photography because you really want to see it with your own eyes," he said. "If you're spending all the time trying to fiddle around with your cameras, then it's sort of a lost opportunity to experience this just unbelievable event."

What if I'm using a smartphone?
With the majority of Americans owning smartphones, millions will likely capture the event with an iPhone or Android camera.

UN weather agency issues ‘red alert’ on climate change after record heat

 UN weather agency issues ‘red alert’ on climate change after record heat

The World Meteorological Organization warns there is a ‘high probability’ that 2024 will be another record-hot year.

The United Nations’ weather agency is sounding a “red alert” about global warming, citing record-breaking increases last year in greenhouse gases, land and water temperatures and the melting of glaciers and sea ice.


The World Meteorological Organization (WMO) said in a report released on Tuesday that there is a “high probability” that 2024 will be another record-hot year and warned that the world’s efforts to reverse the trend have been inadequate.


The Geneva-based agency voiced concerns in its State of the Global Climate report that a crucial climate goal is increasingly in jeopardy: limiting planetary warming to no more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) from pre-industrial levels.

“Never have we been so close – albeit on a temporary basis at the moment – to the 1.5C lower limit of the Paris Agreement on climate change,” said Celeste Saulo, the agency’s secretary-general. “The WMO community is sounding the red alert to the world.”


The 12-month period from March 2023 to February 2024 pushed beyond that 1.5-degree limit, averaging 1.56C (2.81F) higher, according to the European Union’s Copernicus Climate Change Service.


It said the calendar year 2023 was just below 1.5C at 1.48C (2.66 F), but a record-breaking start to this year pushed the 12-month average beyond that level.



“Earth’s issuing a distress call,” UN Secretary-General Antonio Guterres said. “The latest State of the Global Climate report shows a planet on the brink. Fossil fuel pollution is sending climate chaos off the charts.”


Omar Baddour, WMO’s chief of climate monitoring, said the year after an El Nino event – the cyclical warming of the Pacific Ocean that affects global weather patterns – normally tends to be warmer.


“So we cannot say definitively that 2024 is going to be the warmest year. But what I would say: There is a high probability that 2024 will again break the record of 2023, but let’s wait and see,” he said. “January was the warmest January on record. So the records are still being broken.”

The latest WMO findings are especially striking when compiled in a single report.

In 2023, over 90 percent of ocean waters experienced heatwave conditions at least once.


Glaciers monitored since 1950 lost the most ice on record. Antarctic sea ice retreated to its lowest level ever.


WMO said the impact of heatwaves, floods, droughts, wildfires and tropical cyclones, exacerbated by climate change, was felt in lives and livelihoods on every continent in 2023.


But the agency also acknowledged “a glimmer of hope” in trying to keep the Earth from running too high a fever.


It said renewable energy generation capacity from wind, solar, and water power rose nearly 50 percent from 2022 to 510 gigawatts.


The report comes as climate experts and government ministers are to gather in the Danish capital, Copenhagen, on Thursday and Friday to press for greater climate action, including increased national commitments to fight global warming.
