Asia: Lives upended in cyclone disasters, ‘extreme’ rainfall on the rise - UN agencies
Across southeast Asia, record-breaking rains and flooding caused by back-to-back tropical storms have claimed hundreds of lives and brought devastation and displacement upon entire communities, UN agencies said on Tuesday.
World Meteorological Organization (WMO) spokesperson Clare Nullis told reporters in Geneva that Indonesia, the Philippines, Sri Lanka, Thailand and Vietnam are among the countries most affected by what she described a “a combination of monsoon-related rainfall and tropical cyclone activity”.
“Asia is very, very vulnerable to floods,” Ms. Nullis said, explaining that flooding consistently tops the list of climate hazards in the region according to WMO’s annual “State of the Climate” reports.
However, she said that tropical cyclones such as Senyar, which last week brought “torrential rainfall and widespread flooding and landslides” across northern Sumatra in Indonesia, peninsular Malaysia and southern Thailand, are rare so close to the Equator.
“It's not something that we see very often and it means the impacts are magnified because local communities… have got no experience in this,” she stressed.
The UN weather agency spokesperson quoted Tuesday’s figures from the Indonesian National Disaster Office indicating 604 fatalities, 464 people missing and 2,600 injured. In total, some 1.5 million people have been affected in Indonesia and more than 570,000 have been displaced.
Turning to Viet Nam, Ms. Nullis said that the south Asian nation has been “battered now for weeks” and is “bracing for yet more heavy rainfall”.
“Exceptional rains in the past few weeks have flooded historic sites, popular tourist resorts and caused massive damages,” she said.
In late October, one meteorological station in central Viet Nam recorded a national 24-hour rainfall record of 1,739 millimetres, which Ms. Nullis described as “really enormous”.
“It's the second-highest known total anywhere in the world for 24-hour rainfall,” she said.
This exceptionally high value is currently subject to a formal WMO extremes evaluation committee. According to the agency, a value above 1,700 mm would constitute a record for the Northern Hemisphere and Asia.
Ricardo Pires, spokesperson for the UN Children’s Fund (UNICEF), described what he called a “fast-moving humanitarian emergency” in Sri Lanka, after Cyclone Ditwah made landfall on the country’s east coast last week, affecting some 1.4 million people including 275,000 children.
“With communications down and roads blocked, the true number of children impacted is likely even higher,” Mr. Pires warned. “Homes have been swept away, entire communities isolated, and the essential services children rely on, such as water, healthcare and schooling have been severely disrupted.”
The UNICEF spokesperson stressed that displacement has forced families into unsafe and overcrowded shelters, while the flooding and damaged water systems are increasing disease outbreak risks.
“The needs far outweigh the available resources right now,” he insisted, in an appeal for additional humanitarian funding and support for the most vulnerable.
Commenting on the intensity of the devastating weather events WMO’s Ms. Nullis explained that rising temperatures “increase the potential risk of more extreme rainfall because a warmer atmosphere holds more moisture”.
“That's the law of physics… we are seeing more extreme rainfall and we will continue to do so in the future,” she concluded.

As world’s water reserves change, countries must prepare for a new reality: WMO
New data showing that rivers were at their lowest level for decades last year provides further evidence that the climate crisis is real and countries must act immediately to protect themselves from the increasing threat to communities and livelihoods, the UN World Meteorological Organization (WMO) said on Thursday.
The key findings from WMO’s State of Global Water Resources 2025 report covering the hydrological cycle and extreme events in the five-year period to last year:
- 2025 was one of driest years for river discharge in 35 years
- Past seven years have seen abnorfmal river flows
- Water storage on Earth’s land surface has decreased in past decade
- Widespread glacier loss across all regions for fourth consecutive year
- Asia and Africa are regions most affected by water-related disasters
- Water data availability has improved, but gaps remain in hard-hit areas
Highlighting the long-term decline in the Earth’s freshwater storage and glacier melt, WMO Secretary-General Celeste Saulo explained that the planet’s water reserves used to act as a planetary “savings account” that absorbed the occasional dry season, avoiding a water crisis. “One of the central stories of the 2025 report is what is happening to that savings account? And the simple answer is that we are depleting it,” she told journalists in Geneva.
Groundwater reserves are equally stretched and have been in decline since 2014, WMO’s report states, with nearly two-thirds of monitored wells worldwide showing levels lower than the historical norm and indicating a shift “further toward deficit…not recovery”.
“At the same time, we are seeing more water-related disasters,” Ms. Saulo said, while also stressing that the currently strengthening El Niño “will increase the risk of drought in some areas, and flooding in others”.
Glaciers disappearing
In 2025, for the fourth consecutive year, every major glaciated region on Earth lost ice mass, leading to short-term hazards including floods and long-term water insecurity, according to WMO.
Responding to a question about whether the changing global water cycle might have contributed to the deadly Nepal-China flooding disaster, Ms. Saulo explained that melting ice and rock was just one factor in the chain of events that ultimately sent a massive and deadly wall of water and debris downstream on 26 August, killing at least 1,367 people.
“You asked if it could happen again? Absolutely; the problem in this region is that there’s 63,700 glaciers at the last count,” she told a Press Conference in Geneva. “Even if you’re looking with remote sensing with satellites at these glaciers, you might see some faults, you might see some slight shifting, that does not mean necessarily catastrophic collapse. So, in order to plan for this, it’s very, very difficult. But the international community is looking very hard at ways in which we can bring people together to solve some of these monitoring issues.”
Data indicates that glaciers shrank between 2023 and 2025 with cumulative losses of 1,400 gigatonnes of water – or about one third of annual fresh water needs.
Every major glacier region on Earth lost ice for the fourth consecutive year.
“All 19 glacier regions around the globe lost ice; in Central Asia, Iceland, the Russian Arctic and western Canada and the United States, it was among the three worst years on record,” said Wayne Jenkinson, WMO’s Director of Hydrology and Cryosphere.
Some regions with smaller glaciers such as Central Europe, the Caucasus, the western Canada and the United States may already have reached “peak water”, Mr. Jenkinson warned.
“After this point, the glacier gives less meltwater each year simply because there is less ice left to melt. That matters for every community downstream that relies on water during hot, dry summers,” he explained.
Narelle van der Wel, WMO’s Head of Cryosphere Monitoring, Predictions and Services, stressed that while some further glacier loss is unavoidable, the eventual scale of the decline is not predetermined.
“Some glacier loss is inevitable, but total loss of glaciers is not yet inevitable,” she said, pointing to emissions reductions as central to limiting future losses.
Preparing for moving baselines
The report does not attribute every observed change to climate change alone. WMO says pressure on water resources and natural variability also contribute.
Mr. Jenkinson said governments need to prepare for “moving baselines” as historical patterns become less reliable.
“The situation 30 years ago is not where we are today,” he said. Countries, he added, need to prepare “for those changes that have really already arrived”.
