Severe floods caused by monsoon rains have killed more than 30 people and displaced tens of thousands in Malaysia and southern Thailand, with both countries preparing shelters and evacuation plans in anticipation of more heavy rain.

The devastation extends beyond Malaysia, with neighbouring Thailand also grappling with the aftermath of heavy rainfall. Flooding in southern Thailand has claimed 25 lives and affected over 300,000 households, with thousands of people still staying in shelters.

Severe floods caused by monsoon rains killed more than 30 people and displaced tens of thousands in Malaysia and southern Thailand, officials said Tuesday, with both countries preparing shelters and evacuation plans in anticipation of more heavy rain.

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.

Severe flooding caused by days of torrential rain has forced over 122,000 people to evacuate their homes across Malaysia, with disaster officials confirming three fatalities. Authorities warn that the numbers could rise as heavy rain and storm warnings persist.

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 National Disaster Command Center online portal said Friday that 84,597 people, from more than 25,000 families, across seven states were evacuated to 488 temporary shelters.
