The Department of Irrigation and Drainage (DID) has warned of more floods in the comings days as the monsoon season, which lasts from October to March, carries on. Authorities urged residents to evacuate if possible.
The intense rainfall in Kelantan hit a record of 627mm on Sunday, the highest since 1967, said the DID.
The Malaysian Fire and Rescue Department said that it has mobilised 18,053 members including the Volunteer Fire Brigade and Auxiliary Fire Officers throughout the country to help with flood rescue operations.
It is also activating helicopters and drones for severely affected areas.
Experts have said rapid urbanisation and conversion of forests into settlements and industrial agriculture have made even inland areas, including capital city Kuala Lumpur, increasingly vulnerable to extreme floods as rainstorms intensify due to climate change.
