We will be closing this live page soon, but before we do, here’s a look at the day’s major developments:

• More than 1,140 people have been killed in floods across Indonesia, Sri Lanka, Thailand and Malaysia.
• A deluge of showers has been reported in India’s southern state of Tamil Nadu as Deep Depression Ditwah, downgraded from cyclone,  moves northwards. Some flight cancellations have been reported between Chennai and Port Blair.
• Electricity supplies are being restored in the Indonesian province of West Sumatra, but power remains disrupted in North Sumatra and Aceh.
• Tens of thousands of children are out of school in Indonesia and Thailand due to the floods and landslides.
• Experts say devastating flooding in Asia can be attributed, in part, to prolonged La Nina cycles, which are making rain-heavy storms and monsoons stronger.
• Sri Lanka’s president has declared a state of emergency to deal with the disaster.

In Sri Lanka, the monsoon season typically lasts from about June to September.

However, this year it has been exacerbated by two separate cyclonic storm systems: Ditwah and Senyar. Ditwah first formed as a deep depression over the Bay of Bengal. It made landfall on Friday in Sri Lanka, triggering mass floods and landslides, before shifting back over the bay.

The storm is expected to weaken as it moves north, deluging India’s southern coast with heavy rains.

In Indonesia and Thailand, Senyar formed in the Strait of Malacca, a stretch of water connecting the Indian Ocean and the South China Sea.

Senyar brought enormous rainfall, high-speed winds and waves to Indonesia’s island of Sumatra and at least eight southern Thai provinces. The storm also brushed neighbouring Malaysia, killing two people.

The director-general of Sri Lanka’s disaster management centre says the country is facing a “humanitarian crisis of historic proportions” as more than 1.1 million people are displaced by floods and landslides.

All 25 districts have been affected, Sampath Kotuwegoda told Al Jazeera, as the country continues to deploy rescue missions to search for the missing and help survivors.

“We have to resettle people, we have to rebuild the nation again and this is going to be a huge task,” Kotuwegoda said.

Neighbouring countries including India, Pakistan, Bangladesh and Japan have sent emergency management teams, Kotuwegoda added, but more international support is needed to respond to the needs.

In Indonesia’s Palembayan, row after row of houses have collapsed, with crushed vehicles dotted along mud-laden streets and piles of motorcycles tangled up in heaps after being carried away by landslides and fast-flowing floodwaters.

Rescue teams were seen carrying away a body across a swathe of rural land now covered in debris, uprooted trees and household furniture.

“These used to be the houses of my parents, my brother; also, my rice-milling place. Now all are gone,” said Muhammad Rais, who lives in Palembayan and lost two family members.

“We have nothing left.”

As the death toll on Indonesia’s island of Sumatra climbs to 604, Minister of Home Affairs Tito Karnavian says the government was not ready to manage the fallout.

The comments came during a coordination meeting in the capital Jakarta.

“The disaster is quite extensive in Aceh, North Sumatra and West Sumatra,” Indonesian outlet Tempo reported Tito as saying.

“Similar to what happened in North Sumatra, it happened very quickly, and maybe we were not prepared for it.”

At the same meeting, head of the Indonesian Meteorology, Climatology, and Geophysics Agency Teuku Faisal Fathani said he had warned local governments of tropical Cyclone Senyar eight days before it made landfall, repeating the warning again four and two days before it hit.

Throughout the catastrophic flooding that rocked Sumatra over the weekend, residents noted a common phenomenon – huge piles of logs that crowded on shorelines, rumbled through floodwaters, and piled up where homes once stood.

Although at first the Environment Ministry dismissed accusations that the logs may have originated from illegal logging activities, officials have since pledged to investigate, Antara news agency reported.

“The circulating information said it was the result of illegal logging, some said it was rotten wood,” Home Affairs Minister Tito Karnavian told reporters.

“However, I cannot answer something I haven’t seen myself, nor have I obtained official data, and I need to investigate with law enforcement officials.”

The Forestry Ministry separately said it would investigate the logs’ provenance.

From 2001 to 2024, Indonesia lost 320,000sq km (123,553sq miles) of tree cover, according to watchdog Global Forest Watch, equivalent to about 20 percent of its total tree cover area in 2000.

Tens of thousands of children are out of school in Indonesia and Thailand due to the floods and landslides, Save the Children has said.

According to an assessment carried out by the organisation, about 76,000 children are out of school in southern Thailand.

In Indonesia, at least 1,000 schools have been damaged and closed in Aceh and Sumatra, with others being used as emergency shelters.

The International Federation of Red Cross and Red Crescent Societies has called for better early warning systems and an “urgent need for stronger legal and policy frameworks to protect people in disasters” in the wake of deadly floods and mudslides in Asia.

“Families have lost homes and incomes, and thousands are sheltering in evacuation centers. Health risks from waterborne diseases and sanitation challenges are rising, while flooded roads and damaged bridges are cutting off access to essential services,” it said in a press release.

Alexander Matheou, IFRC director for the Asia Pacific region, said there is a need for “better early warning systems, shelter for people to go to in times of flooding, more nature-based solutions … social protection systems in disaster”.

“These floods are a stark reminder that climate-driven disasters are becoming the new normal, and investment in resilience and preparedness is critical,” the statement added.

Services are slowly returning to Thailand’s hardest-hit southern province of Songkhla, where at least 131 people have been killed.

About 80 percent of the province’s tap water has returned for use, the Thai Enquirer reported, citing the provincial water authority. Full water service is expected by Wednesday.

Three mobile water treatment units are pumping out about 180,000 litres (48,000 gallons) daily, while the first batch of about 26,000 residents is expected to receive 9,000 baht ($282) each in assistance payments starting today.

As Sri Lanka, Indonesia, Thailand and parts of Malaysia reel from deadly floods and mudslides, Pakistan is another country in Asia that has faced catastrophic flooding this year.

Since June, flooding across Pakistan has displaced more than four million people, killed at least 1,000, damaged more than 230,000 houses and washed away almost 23,000 livestock.

Climate change is seen as one of several factors contributing to the deluge. Pakistan ranks among the top 10 most climate-vulnerable nations, but it contributes less than 1 percent of global emissions.
