Malaysia, southern Thailand and parts of the Philippines have been battered by heavy rain and flash floods in recent days, killing dozens, officials said on Tuesday.
Malaysia's worst flooding in a decade forced nearly a quarter of a million people from their homes, officials said.
North-eastern Malaysia and southern Thailand are hit by flooding during the annual northeast monsoon but this year the rain has been particularly heavy.
10,000 evacuated
Five southern Thai provinces - Narathiwat, Yala, Pattani, Phatthalung and Songkhla - were still flooded. Nearly 10,000 people have been evacuated.
A tropical storm has dumped heavy rains and brought flash floods and mudslides to the central and southern Philippines, parts of which were battered by two recent strong typhoons, killing 16 people.
Five people died when a mudslide buried a house in Tanauan town in Leyte.
