( CNN ) Even by Malaysian standards , this flooding is epic . Neighborhoods turned into islands surrounded by a sea of murky brown water . Streets doubling as rivers . Cars swept away and toppled over . The flooding has forced more than 132,000 people to evacuate , Malaysia 's official Bernama news agency said . Strong currents and interrupted power supply are adding to the chaos , Prime Minister Datuk Seri Najib Tun Razak told reporters . `` Clean water supply too can not be delivered , and flood victims at the temporary relief centers had to endure darkness without electric supply , '' he said , according to Bernama . The flooding ravaging Malaysia started more than a week ago . While the region is accustomed to monsoons , the `` northeast monsoon '' that has gripped Malaysia , Indonesia and southern Thailand is particularly harsh . Here 's how it works , CNN meteorologist Derek Van Dam said Saturday : . Strong high pressure develops over Eastern Europe and China and strengthens northeasterly winds from the South China Sea , bringing heavier rainfall over Malaysia , Indonesia and southern Thailand . And it 's going to get worse . Another 100 millimeters ( 4 inches ) of rain could fall over the next two days near the Malaysia-Thailand border , he said . `` That leaves open all kinds of possibilities -- more flooding , and the possibility of landslides and mudslides , '' Van Dam said . Across the Bay of Bengal , Sri Lanka has been hit hard , too . Kandy , in the center of the island nation , received more than twice the average monthly rainfall in just the past eight days , Van Dam said . CNN 's Radina Gigova contributed to this report .
