Heavy rain in Malaysia, Flooding in Kuala Lumpur and SE Asia Weather Updates 02 May 2012

The ITCZ has brought heavy showers across the South East Asia specifically Malaysia and Singapore. Kuala Lumpur, the capital city of Malaysia is reported being hit by flash flood just few hours ago. Several town in Kuala Lumpur is under water causing traffic havoc across the city. The heavy downpour, reported to have started during the afternoon, lasted for approximately 4 and a half hour causing immediate rise of river level and flash flood in low lying area. Isohyet below showing the amount of rainfall for the Peninsula Malaysia for the past 18 hour starting from 0000AM (MAL/PHIL) / 1600Z.

Information obtained from the Malaysia Drainage and Irrigation Department indicates further that Kuala Lumpur region has received heavy rainfall specifically in Kg. Cheras Baru – Kuala Lumpur (135mm), Ladang Edinburgh – Kuala Lumpur (100mm), Taman Sri Muda – Petaling (121mm). The low lying area of Klang, which is regarded as the black spot for flooding, accumulated rainfall amounted between 70 – 100mm. The Kuala Lumpur Smart Tunnel, which was build meant to be utilized for both traffic and flood diversion, is reported to have closed down for public in order to divert overflow water to the other end of town.

Over in the North, in the states of Perak and Kedah, similar heavy rainfall weather is reported but no flooding is reported at press. Meanwhile over the eastern Peninsula Malaysia, hot weather continue to linger around the region with most of the area experiencing fair weather.

Back to the South East Asia, I have posted the SE Asia 3 days forecast in a newly developed page. That particular page serves specifically for the 3 days update. Please do have a look here at South East Asia 3-days Outlook. If you have any suggestions or comments I can further improvise the information provided, please leave your comment or suggestion in the comment box below.

Next, over the Philippine, a developing low is coming up and currently known as Invest 98w. We are still monitoring the system and if you are interested in following this system or to contribute your information on the ground to the team, please do so in our discussion forum here at Western Pacific Weather Forum

Finally I will leave everyone with some flood photos that I have manage to get from the internet. Also, an amateur video on the flooding.

Stay safe and have a good day.

Heavy rain over Hong Kong, developing Invest 97W and WestPac Wx SE Asia Weather Update 29 Apr 2012

Good day everyone and today yet another South East Asia updates from me at here. Two attention point to look on today’s weather here in the western pacific. The first we would be looking at the heavy thunderstorm over Hong Kong due to an area of low pressure with heavy rain amounted to more than 150mm has been reported there by fellow friends James Reynolds a.k.a TyphoonFury. Next, Invest 97W has now been officially recognized as a Tropical Depression by JMA. But before moving further, the following is the Weather Maps produced by the Thailand Meteorological Department earlier today.

At least six to seven area of low pressure can be observed from the above weather maps and this definitely means alot of rainfall occurring all over the place in the region. Also, we do have a stationary front located in Mainland China just north of Taiwan and surely it has dropped ample amount of rainfall over Taiwan and it is currently moving east ward over to Japan.

A look at the Isohyet Chart for the past 24 hour from Hong Kong Observatory, we can see that a very heavy amount of precipitation has been dump over Hong Kong with several area receiving rainfall between 150mm to 200mm namely Tuen Mun and Tsuen Wan, cities like Yuen Long, Sha Tin and Sai Kung also received amount of rainfall over 100mm for the past 24 hour and unofficial report saying that flash flood has occurred in some low lying area in Hong Kong. At press, weather is reported to be fair with most of the area are receiving precipitation below 10mm for the past hour.

Meanwhile over the Philippine, Invest 97w as per mentioned in my previous post, if able to sustain the high pressure windshear for the next 48 to 36 hour it would be regaining its strength and early today, it is reported that the system is reorganizing and is moving fast towards Mindanao. Satellite imagery shows an impressive convective banding over the system with winds near the centre of the system was about 10 – 20 knots. Detailed information has been posted by Adonis earlier today HERE. More information will be uploaded from time to time if the system is going to develop into a Tropical Cyclone.

Back to the South East Asia, below are the official weather forecast for the next 3 days released by the Malaysia Meteorological Department for the Peninsula Malaysia and also the Borneo states. Generally, most of the states will experienced isolated thunderstorms and isolated rain in the afternoon with estimated temperature of 24 Celsius to 32 Celsius.

Over in Singapore, the Singapore Weather Agency forecast that for the coming 3 days, please do expect some late morning and afternoon thundery showers with a low of 25 Celsius and a high of 32 Celsius.

Finally over in Brunei, the Brunei Weather Agency forecast Thunder showers and Showers occurring over the state for the next three days with temperature ranging from 25 Celsius to 32 Celsius.

Before I wrap up my updates, I would like to make a note to all my viewer that my post was being copied over to the following website without my consensus. I am not going to argue with the owner of the site as previously few of the authors here experienced the same thing and if you, the viewer have surf the site, you would be surprised that most of the post here is being published over there mostly without the authors consensus.
Above is the link to one of my post that is “moved” to the site there. Nevertheless, my intention is just to remind all our viewers that the every piece of the news posted here is the original work of our author namely Robert Speta, rpweather (Pat), Weatherguy Adonis, and me Francis Chuah. So do remember that whenever you similar post elsewhere, please be notified that the post was originally written here. Thank you.

That’s all from me right now. The next similar update will be on the 2nd of May. But do stay tune from time to time updates on the severe weather happening now in the Western Pacific Basin. Stay safe and have a good day.

WestPac Wx SE Asia Weather Update 26 Apr 2012

The weather in the South East Asia has been wet for several days as 2 low pressure was lingering around the region. Currently the two are of low pressure is further north in Northern Thailand and Vietnam bringing a heavy amount of heavy rain in the region but still, the South East Asia region has been affected partially by the system. Over on the Philippines, Invest 97w that kicks off with a strong potential as the first Tropical Cyclone for the PI is currently being tear off by the Ridge of High in the North East Philippines sea which has resulted the system to lost its organization and formation. Model forecast such as NoGaps and GFS has it nothing more than a low pressure as of now but if the system manage to survives for the next 24 to 48 hour, there is a possibility of regaining strength and end up as a tropical system.

Overall in Malaysia, weather will remains wet for the coming three days and earlier this week we did received news that flash flood occurs over the Borneo Island in Sabah, specifically the area of Lahad Datu. I have yet to receive consensus from a photo owner located in that area therefore I am not able to post the flood photo here for everyone. Following is the forecast of three days weather from the Malaysia Meteorological Department (MMD). I know is a bit lengthy but I will try my best to make a shorter version in my next updates.

Over in Singapore, the Singapore Weather Agency forecast that late morning and afternoon thunder showers for the next 3 days with temperature of 24 – 32 Degree Celsius.

And finally over Brunei, the Brunei Weather Agency also forecast similar wet weather over the states with Thunder showers and Showers occurring over the state for the next three days with temperature ranging from 25 Celsius to 32 Celsius.

That’s all from me right now, will have another similar updates on the 29th April (Sunday) if possible.
Stay safe and have a good day.

WestPac Wx SE Asia Weather Updates 18 April 2012

Another great day for some updates in the weather across the South East Asia region. As we can see from the above image, much of the area in the South East Asia is currently having heavy precipitation due to the sea breeze effects especially the Peninsula Malaysia and the Borneo Island. But the main focus for this update will be the heavy rainfall occurring over the Northern Thailand and also the low area that is currently bombarding Hong Kong (See rob’s video update earlier for more information).

The image on the side is the Isohyet map of rainfall accumulation for Thailand on the 17 April 2012. It is a cumulative rainfall for the duration of 24 hour. We can see here that for the past 24 hour the Northern Thailand has received much amount of precipitation. Information obtained from WMO shows that several area in Thailand received rainfall between 30mm to 60mm over the past 24 hour. Leoi Agromet received rainfall of 63.4mm, Ranong 51.1mm and Phuket airport recorded an amount of rainfall of 61.5mm. Additional information from Thailand Meteorology Department indicates that other area in the state also receive plenty amount of rainfall i.e Wichian Buri (35.5mm), Sakon Nakhon Agromet (38.2mm) and Trang Airport (32.8mm). Good news is with this amount of heavy rainfall, it has yet to cause any threats of flooding. The threat of mass flooding similar to last year is no where to be seen as this particular moment.

Meanwhile over in Hong Kong, heavy rainfall still affecting the area include some territory of the Republic of China. Xinyi recorded an amount of rainfall of 60.4mm while ShangChuanDao (71.9mm) and YangJiang (80.3mm). The above mentioned rainfall amount was obtained from the WMO. The heavy precipitation occurring over this region is due to a low that is currently affecting the coastal region of Hong Kong and China. Both NoGaps and GFS model forecast that this rough weather will remain in the region until the end of the week. Fair weather should began to get back to the region beginning early of next week.

Further to the South, in the Peninsula Malaysia, the amount of rainfall received has shown decreases compare to several days ago. The northern region states, which was bombarded with heavy amount of rainfall just few days ago (refer to my post on the 16 April), has been receiving just a little amount of scattered rainfall. However, things are different in the East Coast and Southern Peninsula Malaysia. The Isohyet map dated 17 April 2012 (yesterday) indicates that several area (coloured zone) has received rainfall amounted up to 100mm for the past 24 hour. And over in the Borneo Island, weather has been clear for the past 24 hour except with some scattered thunder shower in several area resulting rainfall amounted between 10mm to 30mm for the past 24 hour. As far as concern, both NoGaps and GFS model are forecasting fair weather over the Peninsula Malaysia, Singapore and the Borneo Island for the coming few days but do expect isolated and scattered rain in the region.

This is in line with both Singaore and Brunei weather agency forecast that scattered rain shower is expected for the coming 3 days expecially in the late morning and early afternoon.

And finally, over the PI, hot weather has been surrounding the state with a high temperature of 39 Celcius being recorded in certain parts of PI. Over the Northern Luzon, it has been a very hot weather. Meanwhile over the South, heavy rains is being reported in some area with most area are cloudy but temperature remains high. For further in depth weather analysis in the PI, please do stay tuned in the site for Pat’s Philippines 3-Day Forecast tomorrow.

That’s all for me today. If you have any comments or suggestion please feel free to post on the comment box below. Stay safe and have a good day everyone.
