Malaysia and Thailand are facing a second wave of heavy rain and potential flooding this week, authorities said on Monday, even as some displaced residents were able to return home and the worst floods in decades began receding in some areas.

Intense rain and flooding have killed several people and displaced over 100,000 across regions of northern Malaysia and southern Thailand. Officials warn this year could bring the worst flooding in a decade to the region.

The Malaysian Department of Social Welfare reported late Monday that over 95,000 people across eight states were forced to evacuate to over 400 temporary relief centers. Kelantan continued to record the highest number of evacuees at 58,146, followed by Terengganu, 27,544, Kedah, 7,426, and Pahang, 1,847.
