All set for north-east monsoon


PUCHONG: All eyes are on the skies as Malaysia braces for the north-east monsoon.

Heavy, continuous rains are on the horizon, with Sabah forecast to experience above-average rainfall due to the La Nina weather phenomenon.

Authorities, meanwhile, are all geared up to tackle this head-on, with more than 100,000 personnel and nearly 40,000 assets ready nationwide 

 



“Among the forecast areas are the east coast and north of Sabah,” he said during a media engagement event organised by the National Disaster Management Agency (Nadma) on preparations for the north-east monsoon here yesterday.

He said Sabah is expected to experience episodes of above- average rainfall between Dec-ember and February.

“Our teams will be monitoring the situation daily,” he said.

Ambun said Kelantan, Tereng­ganu, Pahang, Johor and Sarawak are also forecast to experience heavy, continuous downpours between November and Dec-ember.

The situation is expected to persist in Pahang, Johor, Sabah, and Sarawak in January next year.

Sabah and Sarawak are also forecast to experience heavy, continuous rainfall next February.

“The said areas are expected to receive regular rainfall except for Sabah. Below average rainfall has, meanwhile, been forecast in west Sarawak in March next year,” he said.

Ambun said warnings on extreme weather episodes will be issued at least a week prior to the incidents.

Warnings on continuous rain, strong winds, and rough seas will also be issued at least three days prior to the episodes.

“Updated forecasts will be issued daily,” he said.

Nadma director-general Datuk Abdul Halim Hamzah said more than 100,000 personnel will be on standby for the coming north-east monsoon season.

This comprises personnel from the Armed Forces (4,770), police (20,600), Fire and Rescue Depart­ment (15,640), Civil Defence Force (15,390), and Rela (47,100).

Close to 40,000 assets have also been readied in preparation for the year-end monsoon.

This includes 2,555 boats, 1,843 four-wheel drives, 1,172 trucks, 25 helicopters, and 34,092 lifejackets.

He added that 3,683 flood hotspots have been identified nationwide based on Irrigation and Drainage Department findings.

“Regardless, the government is prepared for the coming north-east monsoon season,” he told reporters after the briefing yesterday.

Abdul Halim said coordination among agencies has been improved compared with the north-east monsoon last year.

“The distribution of the Bantuan Wang Ihsan aid has also been improved, with more efficient payouts,” he said.

He added that residents play an equally vital role in flood operations.

“Take note of the early signs, such as rising waters, among others. Please evacuate once you notice this,” he said.

On a related matter, Fire and Rescue Department director-general Datuk Seri Nor Hisham Mohammad said 29 specialised rapid response teams are on standby nationwide to strengthen flood rescues.

He said these teams will focus solely on floods to minimise disruption to daily station operations.

“Our stations have boats and other flood rescue assets, but officers must also stand by for fires and other emergencies. The rapid response teams, however, will be ready to respond to flood emergencies directly,” he said.

He added that each team comprises about 18 personnel and that several operating bases nation­­­wide have been established to store flood rescue assets.

“If there is a forecast, the team can obtain the assets there directly,” he added.

More heavy rain and flooding expected in Oct, says MetMalaysia

PETALING JAYA: The heavy rains and deadly Sabah floods and landslides have already claimed 13 lives.

But meteorologists warn that this could only mark the start of a more dangerous monsoon season.

There is likely to be worse weather ahead as Malaysia transitions from the southwest to the northeast monsoon.

“Thunderstorms and heavy rains are on the horizon in October. 

“From mid-November, the northeast monsoon will bring continuous rainfall, affecting the east coast of the peninsula, Sabah and Sarawak,” Malaysian Meteorological Department (MetMalaysia) director-general Dr Mohd Hisham Mohd Anip says.

He noted that these weather patterns will particularly affect the western and inland regions of the peninsula, as well as western and central Sarawak and western Sabah, with the most intense activity occurring in the afternoons and early evenings.

Hisham warned that low-lying and riverbank areas could see flash floods.

“Climate change is causing more frequent and extreme weather events, including heavier rainfall and severe thunderstorms accompanied by hailstorms and tornadoes.

“It’s essential to understand our climate patterns and plan travel to avoid high-risk areas during adverse weather,” he said.

Climatologists anticipate wetter and more extreme weather in the coming months due to climate change and the La Nina phenomenon.

Dr Fredolin Tangang of the Academy of Sciences Malaysia highlighted a report from the US Climate Prediction Centre, which predicts a more than 70% chance of Pacific Ocean cooling between October and December.

“This will lead to high atmospheric moisture during the northeast monsoon starting mid-November, increasing the likelihood of extreme weather,” he said.

Tangang noted that global warming exacerbates these conditions by increasing the atmosphere’s moisture capacity, causing more and heavier rain.

He warned that the La Nina effect, combined with global warming, is likely to persist, heightening the risk of extreme rainfall, floods and landslides in Malaysia, particularly in Sabah and Sarawak.

“Proper maintenance of drainage systems is crucial to manage the increased rainfall,” he added

Meteorologist Prof Datuk Dr Azizan Abu Samah also predicted heavier rainfall due to La Nina.

“Although currently in an ENSO-neutral state, forecasts indicate a weak La Nina this winter, suggesting above-average rain during the northeast monsoon,” he said.

The inter-monsoon transition is expected around October to November as the southwest monsoon weakens.

Azizan said the recent heavy rainfall in Sabah was due to a westerly southwest wind and the Madden-Julian Oscillation (MJO) interacting with a cyclonic low pressure north of the Philippines.

“The wet phase of the MJO should end by this weekend, providing relief to Sabah and Sarawak,” he said.

The National Disaster Management Agency (Nadma) reported the end of the southwest monsoon, which began on May 10, has caused some areas to see daily rainfall of over 80mm.

Eastern Sabah is likely to see more thunderstorms and heavy rain, at least until Sept 22.

Squall lines capable of producing severe weather are also expected in western Peninsular Malaysia, western Sabah, and northern Sarawak during early mornings, with thunderstorms likely in other regions during afternoons and evenings.

Nadma director-general Datuk Abdul Halim Hamzah said that the agency was fully prepared, especially after the minor earthquake in Segamat, Johor, and the heavy rains in Sabah.
