The death toll from severe floods and landslides in Indonesia has risen to 442, with 402 people still missing and at least 646 others injured, the national disaster agency reported on Sunday.At least two cities on Indonesia’s hardest-hit Sumatra island remained unreachable on Sunday, prompting authorities to deploy two warships from Jakarta to deliver aid. Rescue teams are working to reach isolated areas where thousands of people are stranded without essential supplies. “There are two cities that require full attention due to being isolated, namely Central Tapanuli and Sibolga,” national disaster agency head Suharyanto said in a statement, as cited by AFP. He added that the ships were expected to arrive in Sibolga on Monday.In Sungai Nyalo village, approximately 100 kilometres from West Sumatra’s capital Padang, floodwaters had largely receded by Sunday, leaving homes, vehicles, and crops covered in thick grey mud.Officials reported on Saturday that people in some areas, growing desperate for relief, have been looting supply lines, as cited by Reuters. In Thailand, where floods have claimed at least 162 lives in one of the country’s worst disasters in a decade, authorities are continuing relief efforts and clearing the damage. The government has announced compensation of up to two million baht ($62,000) for households that lost family members.However, public criticism of the flood response is mounting, and two local officials have been suspended over alleged lapses in their handling of the crisis.Hat Yai, the largest city in Songkhla, recorded 335 mm (13 inches) of rain last Friday, marking its highest single-day rainfall in 300 years amid several days of heavy downpours.In neighbouring Malaysia, about 18,700 people are still staying in evacuation centres, according to the national disaster management agency. Meteorological authorities lifted tropical storm and continuous rain warnings on Saturday and forecast clear skies for much of the country.The annual monsoon season, which usually occurs between June and September, often brings heavy rainfall that can trigger landslides and flash floods.This year, a tropical storm has worsened the situation, contributing to some of the deadliest floods in recent years in both Indonesia and Thailand. Experts say climate change is altering storm patterns, increasing the intensity and duration of the monsoon season, and resulting in heavier rains, stronger wind gusts, and more frequent flash floods.
