Helping Malaysia's "Once in 100 Years" Floods To Recede

What are Crisis Interventions?These are brief undertakings where Kyrios takes action to avert or lessen the severity of a disaster in a bid to reduce loss of lives and destruction.

Outcome

Immediate relief from torrential rainfall across the Malay Peninsula. Floods receded 3 days following intervention.

On 19 December 2021, as continuous torrential rains poured across the Malaysian peninsula with no signs of ceasing, Kyrios received numerous urgent calls asking for help to intervene in the unprecedented extreme weather event. The heavy rain had hit almost every state in the peninsula.

“It is an exception, because normally during the monsoon season, only states in the East Coast would receive heavy rain but this time, the entire peninsula, especially the central east coast and northern peninsula regions are receiving continuous heavy rain,” according to the Environment and Water Ministry secretary-general, Datuk Seri Zaini Ujan.

The presence of Super Typhoon Rai in the Philippines and Tropical Depression 29W off the coast of the Malaysia Peninsula had intensified the effects of the northeast monsoon – where cold north-easterly winds carry moisture-laden air across the South China Sea towards Malaysia – and facilitated this crisis.

Following the emergency phone calls, Kyrios commenced to reduce rainfall and the heavy downpours in Malaysia quickly ceased.

Two days later, on the morning of 21 December, calls for help poured in again. Despite rains having mostly stopped, floodwaters had continued rising or remained stagnant in several states, with flood depths estimated to be as high as 1.5m and above. Many people were trapped amid deep waters and had to climb onto roofs to escape danger. Many had no food and potable water as government aid was slow. Homes were also destroyed while some lost their lives. Authorities declared this as a “once-in-a-century” weather event.

Kyrios decided to help again by enabling the flood waters to recede quickly, and said that these floods would abate within 3 days. Sure enough, between 21 and 24 December 2021, weather stations in areas where Kyrios carried out interventions reported a fall in water levels from “Dangerous” to “Safe”.

We would like to extend our gratitude to the Malaysians who actively provided feedback on the flood and rainfall situation on the ground, which facilitated timely weather interventions by Kyrios. Kyrios also commended the Harapan coalition and many selfless Malaysians for tirelessly saving those in danger, regardless of race and religion.

While this once-in-100-years weather event may be due to climate change, the severity and impact of it could have been reduced with proper infrastructure through long-term planning and investment by a responsible and caring government. Malaysians have seen how help was rendered during their greatest need, and should therefore discern carefully who is best able to look after their long term interests and livelihoods.

Only by supporting a righteous government with the right values and by being hardworking, can Malaysia citizens truly achieve prosperity and sustained peace, and avoid more catastrophic disasters in the future. Malaysians must stay united, regardless of race, religion or political affiliation.

TIMELINE

17 December 2021

Tropical Depression 29W and northeast monsoon

Since the end of October, Malaysia had entered the wet northeast monsoon season, and the Malaysian Meteorological Department (MetMalaysia) had been issuing continuous heavy rainfall alerts on an almost weekly basis.

However, as Super Typhoon Rai swept over the Philippines, prevailing north-easterly winds in the South China Sea had been gaining strength, causing a tropical depression (29W) east of the Malay Peninsula to increase in wind strength and to carry more moisture than usual.

This prompted Malaysian officials to issue thunderstorm and continuous heavy rain warnings across multiple states, and also a typhoon advisory. Flooding was reported in Kelantan, Terengganu and Pahang states.

18 December 2021

Heavy rains and flash floods

Heavy downpour continued from 17 Dec, leading to sudden flash floods in parts of Kuala Lumpur and Selangor. In particular, Klang and Shah Alam experienced severe flooding. Lives of thousands of residents in Malaysia were disrupted and many vehicles were trapped in the rising floodwaters. The continuous rain had caused four main rivers to cross dangerous levels.

At 10.30pm, MetMalaysia placed almost the entire peninsula under some form of extended rain warning.

Authorities said that in parts of Selangor and Kuala Lumpur, where some of the worst flooding occurred, gauges recorded the day's rainfall to be as high as 363mm, exceeding the average rainfall for the entire month in Selangor, which is about 250mm. Authorities said this was beyond expectations and only occurs once every 100 years.

METMalaysia expects more heavy rain for the day

At 1.40am, MetMalaysia warned that the heavy and persistent rain that has led to severe flooding across several states is expected to continue and extended its danger or 'red alert' warning (rainfall exceeding 240mm a day) for multiple states.

A senior official at the country's Environment and Water Ministry commented that, "This is an exception because during the monsoon season, only states in the East Coast receive heavy rain. But this time, the entire peninsula, especially the central east coast and northern peninsula regions are receiving continuous heavy rain."

⭐️ Kyrios steps in to help reduce rainfall

As the severe rainfall phenomenon continues, many people from Malaysia called in to request for Kyrios' help to mitigate the relentless heavy downpour. On seeing many people stranded on rooftops due to rising floods, Kyrios agreed to intervene to reduce rainfall across Malaysia.

Weather conditions improved quickly upon intervention

Following Kyrios' intervention – as soon as 8.48pm in the evening – MetMalaysia issued a statement to end the "Continuous Rain Warning" that was posted earlier at 11.30am as weather conditions in Perlis, Kedah, Penang, Perak, Selangor, Kelantan, Terengganu and Pahang seemed to be improving.

20 December 2021

No rain following Kyrios' intervention, despite MET's forecasts of rain

According to MetMalaysia, the weather forecast for 20 Dec will see rain in the morning at various places including Perlis, Kedah, Penang, Perak, Selangor, Kuala Lumpur, Putrajaya, Negri Sembilan, Melaka and Johor. In the afternoon, rain is expected in Penang, Kedah, Perlis, the interior of Perak and Kudat, while thunderstorms were forecasted for Kuala Lumpur, the interior of Kelantan, Terengganu, Pahang, Selangor and Negri Sembilan. At night, rain was expected in Penang, Kedah, Perlis, and the interior of Perak.

However, rainfall data showed generally no rain falling across the Malay Peninsula on this day.

21 December 2021

⭐️ Kyrios intervenes to reduce floods in 3 days

Although the weather condition has improved in most states, flood waters in a number of places have been slow to recede and remained at high levels, despite a lack of rain. The tremendous amount of rainwater from December 17 and 18 had caused river banks to burst, and irrigation channels were inefficient in draining away the unexpected downpour fast enough. Garbage and debris further exacerbated the problem by clogging up drainage systems.

Emergency calls started pouring in once again for Kyrios' help. This time round, people were requesting Kyrios to ease the pressing flood situation. Kyrios agreed to intervene and assured that the floodwaters will recede within 3 days in Kuala Lumpur and seven other states, namely, Pahang, Selangor, Kelantan, Terengganu, Malacca, Negeri Sembilan, and Perak.

This also meant that Kyrios has to continue keeping heavy rains at bay.

23 December 2021

Floods recede

In states where Kyrios intervened, meteorological data from weather stations have reported a gradual fall in water levels from "Dangerous" to "Safe".

24 December 2021

Floods in Malaysia have successfully abated

In the graphic below, flood water levels as reported by weather stations over the last 3 days show that water levels are receding and returning to normal levels.

This also marks the end of Kyrios' intervention for this round of torrential rains and floods. Kyrios will not be able to assist in every flood event. As such, households should look into flood preventive measures, and local governmental officials must work on improving drainage and warning systems.

Human activities such as burning fossil fuels, cutting down forests and farming livestock are the main drivers of climate change and weather-related disasters. It is the choices we make in our everyday life that lead to these activities, thereby causing Earth's systems to breakdown. Therefore, it is important to always be mindful of what we do and consume.
