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.

Malaysian Prime Minister Anwar Ibrahim said five days of heavier-than-expected rain that battered the country’s east coast last week was equal to the rainfall over the past six months.

Anwar told Parliament on Tuesday that it would cost an estimated 1 billion ringgit ($224 million) to repair infrastructure damaged by the floods.
