KOTA KINABALU - Even with hundreds of families already displaced by floods in various parts of the country, the Meteorological Department has warned of more nasty weather.
Its Sabah director Abdul Malek Tusin said the state was most likely to be hit by the tail end of Typhoon Melor, which is now in central Philippines.
The typhoon is expected to bring strong winds between 64kph and 80kph and heavy rains to Sabah's interiors, west coast areas and Kudat on Thursday and Friday. Waves of up to 3.5m at the Sulu and South China Sea are also expected.
Abdul Malek said the affected areas should brace for flash floods while all sea activities should be halted until the weather improved.
In Kuala Lumpur, the department's deputy director-general Alui Bahari said heavy monsoon rains accompanied by thunderstorms were expected in Terengganu, Pahang, Johor and west Sarawak.
The department has issued a yellow alert, signalling imminent downpours in these areas within one to three days.
He called on the people to prepare for bad weather.
Alui said that they were constantly monitoring the situation and if it were to get worse, the department would issue an orange or red alert.
Orange signifies rain that lasts for more than a day, with an average rainfall of 0.5mm to 4mm per hour.
Red is the highest warning and signifies heavy rain lasting for a day or more, with an average of 20mm of rainfall per hour.
Alui said heavy rains were expected from a cold surge forming over the South China Sea due to north-east winds.
In Malacca, among those reeling from heavy downpours were 150 families in Alor Gajah.
Sunday's heavy rain left several areas in waist-high flood after Sungai Pengkalan burst its banks.
The flood-hit areas include Kampung Gadek, Kampung Pengkalan, Taman Seri Bayu and Kampung Panchor.
In Bukit Mertajam, a freak thunderstorm wreaked havoc on at least 17 village houses in Permatang Janggus, Permatang Pauh.
The roofs were blown away in the 5.20pm storm on Sunday while some ceilings and walls were torn apart, causing residents to suffer damage to their homes amounting to tens of thousands of ringgit.
Homemaker Hazmiza Abu Hassan, whose family was among those affected, said she was taking a nap with her three children when her husband shouted for them to get up upon seeing the twister-like winds moving towards their wooden double-storey house.
"Everything happened so fast and before we knew it, all of us were running out of our house because we feared for our safety," said the 36-year-old mother of four.
In Ipoh, at least 19 families were displaced following a flash flood that hit their village in Parit, Perak Tengah.
A Perak Fire and Rescue Department spokesman said that about 85 people were currently taking shelter at the Nurul Jannah Surau in Parit 6, Layang-Layang Kiri.
"The floodwater was about 0.6m high. Villagers moved to the temporary shelter on Saturday at about 3am," he said.
Meanwhile, a state National Disaster Council secretariat spokesman said four families with 22 people, were relocated to SK Changkat Jong following a flood at Kampung Lorong Mesra in Changkat Jong, Teluk Intan at 6pm yesterday.
