Authorities have set up more than 200 relief shelters for people displaced by the floods, the national disaster management agency said.
Floods in Malaysia are common during the annual monsoon season between October and March, but the downpour this week left many Johor residents scrambling to find shelter.
Flooding resulting from days of torrential rain has forced almost 40,000 people to flee their homes in Malaysia’s southern Johor state, bordering Singapore, and at least four people have died during the past week, officials said.
