One of the worst-affected areas is Aceh province on Sumatra island.

The death toll is currently 96 with 75 people still missing, according to the National Disaster Management Agency.

Evacuation camps are widespread across 20 districts and cities, including 96 locations in Lhokseumawe City. Supplies in shops are running low, while some residents reported children drinking collected rainwater.

Arini Amalia, a resident from Pidie Jaya Regency, told BBC Indonesia how she escaped her home with her elderly grandmother, before trying to return to collect some of her belongings. However, it was too late.

"That was only a matter of minutes," she said.

When the floodwaters finally started receding, the true damage became clear with "only a meter of mud left inside the house".

"According to my grandmother, this is the worst, the worst in her life," Amalia said.

"That's why I'm a little traumatised, because it's like a tsunami."

As we mentioned earlier, South East Asia is facing some of the worst floods the region has seen, which have affected millions.

More than 440 have died in Indonesia as a result of the floods, caused by a rare cyclone. Cyclone Senyar has also brought heavy flooding and landslides to Thailand and Malaysia, where the death tolls stand at 170 and three respectively.

Another three people have died as Tropical Storm Koto approached Vietnam. Days of heavy rain in Vietnam earlier last month have already killed at least 90 people.

Typhoon Kalmaegi, which hit the Philippines in early November, killed nearly 300 people.

In South Asia, Cyclone Ditwah swept through Sri Lanka, causing floods and landslides across the country that has killed more than 330 people. Anura Kumara Dissanayake, the country's president, called it the "most challenging natural disaster" Sri Lanka has seen.

The sheer amount of devastation has been caused by an exceptionally large, long-lasting cluster of thunderstorms, according to Erma Yulihastin, a climate expert at Indonesia's National Research and Innovation Agency.

The average monthly rainfall for affected areas is around 150 mm, she said, but some areas saw more than this in one day.

"If it's above 100 mm in one day, that's extreme, especially if it reaches 200 mm," Yulihastin said.

On 23 November, rainfall on the west coast of Sumatra reached 160 mm a day, while on 24 November it reached 226 mm a day, she said.

Indonesia has been reeling from an exceptionally rare tropical storm, Cyclone Senyar.

It has caused catastrophic landslides, with homes swept away and thousands of buildings submerged.

People are missing in Aceh, North Sumatra and West Sumatra, the National Disaster Management Agency said.

Aid has been sent into affected areas by air and by sea, but some villages have yet to receive anything, and there are reports of people stealing food and water to survive.

Aid has been slow to reach the hardest-hit city of Sibolga and Central Tapanuli district in North Sumatra.

Police spokesperson Ferry Walintukan said they received reports of people breaking into shops in North Sumatra on Saturday evening, and that regional police had been deployed to restore order.

“The looting happened before logistical aid arrived,” Walintukan told the AFP news agency.

“(Residents) didn’t know that aid would come and were worried they would starve.”

Rescuers in Indonesia are continuing their search for at least 400 people who have been reported missing, many believed to be buried under landslides, after cyclonic rains caused disastrous flooding nearly a week ago.

The death toll on the island of Sumatra has risen to more than 440, the government says.

It comes as torrential rain and storms have devastated parts of Thailand, Malaysia, the Philippines and Sri Lanka, affecting millions of people and leaving more than 900 dead across the region this month.
