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.

At least 13 people died and tens of thousands evacuated in one of the worst floods in decades to batter southern Thailand and northern Malaysia.

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.
